But I don't know what I have to indicate in my for loop.
I don't know why my code doesn't work. It doesn't make the average, and it seems my code is correct. So I don't know how I can put other things

What I do, follows your idea ?

Where can I put loop ?

In my code, I do what I want ?

I calculate the average Moy_bar_ for each group of 20 data which comes from Baycentre_ ?

What I do it runs. There are no error message.

But I don't average correctly...

I update my question.

Is it the good way ?

But I have an error (in comment of my update question)

Thank you, your solution runs !

My variable wasn't null.
I've just replaced :
while (line != null) {
by :
while ( (line=reader_trajectoires.ReadLine()) != null) {
And I removed the firt line after while : "line = reader_trajectoires.ReadLine ();"



Thank you :)

Frame is defined at the very bottom of the code, before void start "int frame;". Its initial value is 0, I declared "frame=0;" at the bottom of void start.

nv_data[i] corresponds to names of markers, and nv_data[i].positions corresponds to data corresponding to the positions of markers. These data come from a text file. nv_data[0].positions.Length = nv_data[i].positions.Length = 41.

Ensemble corresponds to GameObjects what I created in my project. Ensemble[0] corresponds to nv_data[0] etc. If I do it, it's to see the movement of each part through my GameObject Ensemble. Ensemble.Length = 13

In the part concerning forces (cpt_f, data_f), I try in the loop to take the average of each 10 lines, in group of 3 data

Here an example of a line :

0,00\t-7,81\t-19,48\t81,90

I want to take data without \t

0,00 -7,81 -19,48 81,90 (without " ")

data_f[cpt_f][0] = 0,00 : the time
data_f[cpt_f][1] = -7,81 : the first datum
data_f[cpt_f][2] = -19,48 : the second datum
data_f[cpt_f][3] = 81,90 : the thrid datum

I want the first, the second and the third datum
I take these data by group of 10 lines
I calculate the average

So I can see with debugger, that I have the first line in line_f
But after I have cpt_f = 0
And I have an error with the line :
split_data_F = line_f.Split (new string[] {"\t"}, StringSplitOptions.RemoveEmptyEntries);

The error message is :
NullReferenceException: Object reference not set to an instance of an object
Donnees.Start () (at Assets/Donnees.cs:170)

It's why I think there is a problem with my loop. This doesn't run, and I don't see why it doesn't run.

Is it more clear ?*

Thank you for your help

cpt contains data.Length about trajetories which come from the text file : "Suj01_PC_DP_M86.txt" (it's the number of lines which are saved in data[]) : data[cpt]

cpt_f contains data.Length about forces which come from the text file : "Suj01_PC_DP_M86_forces.txt".
And it's for cpt_f that I have 0.
Then, I looked lines_f with debugger, and it has the first line that I want to save in data_F[cpt_F] but it seems that the loop doesn't run.

Yes there is an error here, I corrected it :
if ((counter % 9) != 1)
continue;

Now the first part run,
cpt = 41 and not = 0

But now it's cpt_F where there is a problem, cpt_F = 0

int counter = 0;
while (line != null) {
counter++;
line = reader_trajectoires.ReadLine ();

if ((counter % 9) == 1)
continue;

string lines_data;
lines_data = line;

[cpt] = lines_data.Split (new string[] {"\t"}, StringSplitOptions.RemoveEmptyEntries);

cpt ++;

}

I saw with the debugger that in this part, cpt = 0 (ever)
So data[cpt] = null thoughout
But the string lines_data (and also line) has :
"0.04\t0\t0\t0\t-0.407847\t0.824162\t-0.047091\t-0.518739\t0.872472\t0.023845\t-0.615601\t0.928889\t0.143595\t-0.6…"
So we read the line n°3

Thus, we read line but it seems we don't save , and the other problem is that we don't read good line, because we have to read 1 line / 10 ; here we read line[2], so there is a mistake.

Do you see where comes the problem ?

So what is the problem ?

I've ever used this code for another text file with another form. And it runs... But as soon as I use it differently, for another text file, I have problems

Thank you for your help, I've just tried your solution, and I have again the same problem..

I understand what you mean and I try to see what you said.
But in fact, I think the problem with line_f, it's that :
while (line_f != null) {
To my mind, the loop doesn't run at all because the first datum is : 0,00 (it's the time)

How can I write that I want to read all the line of my text file, but when there is 0, I want to continue anyway

Yes there are some data which = 0
But in the loop I have indicated that the reader runs until the end of the text file : while (line != null)
So how can I indicate I take data until the end of the text file but also I take all data even if = 0 ?

All data of nv_data[j-1].positions[i].x and nv_data[j-1].positions[i].z won't be saved in x[i] and y[i] ?

Thank you but can you help me more please ?
I'm going to update my question

So it's correct this solution.
But at the end I had never the good result in my text file. Therefore, I supposed that the problem came from the line : float delta_x = (((nv_data [59].positions [frame] - nv_data [59].positions [frame - 1]).z) * 0.001f);
even though I put frame-20 instead of frame-1 .

In short, you gave me the good solution for this line. Thank you !

Actually the problem wasn't about the line that I indicated. So I told you that this line is correct :

float delta_x = (((nv_data [59].positions [frame] - nv_data [59].positions [frame - 1]).z) * 0.001f);

I had tested it with Debug.Log etc ... And I had the good result at this location.

But in the following. It was about the Time.deltaTime . Because before this code, my old code runs with a different frequency. In short I found the solution.

Actually I have the good code. I just tested.
But I don't have the correct values at the end... when I compare to the older code...

But thank you !

No I didn't know how can I use breakpoint.
Actually I know to use it but I don't know how I can analyse the result.

I think it's not useful to tell you what exact values I much have because they are float, so there are a lot numbers. I know that I have not the correct values because I did this code in a different script. And I compared the both, and there was no connection.

I tried but it doesn't run...
I had wrong result again

Do you see my code ?

Thanks very much again in advance :)

Thank you to want to help me.

So I have just send you the full code with some explanations.

Tell me please if you receive this message and if you want some add explanations, tell me.

I don't understand your different points about reasons of the problem.
Can you explain them, please ?

I tried debugger but it seems that it doesn't bring me more details about my problem.

Frankly, I don't now how I can continue.

I indicate somethings in comments in my code which is in the update question

I modify some things and in particular the frequency that I used for the animation. And now the animation runs but the recording is not correct. I have only one line, corresponding to the fact that the second Debug.Log(frame); shows me only 20 in result.

Look my update question.

The animation doesn't run because I think the code doesn't take 1 line / 20 but all lines so the frequency doesn't good and we can't see anything.
With Debug.Log(frame);
I have either 0 or 0 1 2 3 4 5 6 ... 1 by 1 instead of 1 frame / 20.
I don't understand...

It's right indeed.
I need all lines from the file in void Start.
Then in void FixedUpdate I need to skip some lines : I need 1 line / 20.

But I don't know how I can do it...

I'm sorry to don't explain well

I have to use all of lines in void start.
I have to use 1 line / 20 (so 1 frame / 20) in void FixedUpdate.

But what I did in my code which appears in my question, it doesn't run. So I am searching a solution... But all things what I try , are wrong.

So have you got any ideas to do that ?

Sorry for my previous question "How can I make a different processig in the same code ?" I thought at this moment, that we can to do what I want in void start because I tried already in void FixedUpdate and I didn't arrive to do what I want.

It's what I did, no ?

Why to use a bool here ?
In all of lines of void FixedUpdate I want to use only 1 frame / 20.

I don't understand what I have to do exactly...

Can you explain please ?

I tried already that.

The void start is called only once time, when the code is launched (only at the beginning) so even though I indicate Skip_lines = true in void FixedUpdate, it will change nothing because we don't read again void start.

Do you see what I mean ?

But it doesn't run, I tried these two things.

Actually I don't have to skip lines in void start because I need of all lines in void start for "moindres carrés".
But it's in the second part (in void FixedUpdate) that I need to take only 1 line / 20. So it's here that I have to add somethings.

Indeed, void start is called once time, at the beginning when I launch the code. Thus, if I want something different in void FixedUpdate related to the code presents in void start; I have to add somethings in void FixedUpdate.

I don't know if I am clear :s

In short, I have to indicate I want to take only 1 frame / 20 .

I tried somethings but it doesn't run...

I am going to update my question to show what I did last.

Could you see my update question ?

It's more elaborate I think :)

Finally it doesn't run as I did that... !
It's like Skip_lines = true every time as soon as this part of the code :
if (Skip_lines = true && (counter % 19) != 1)
continue;

I put "Debug.Log (Skip_lines);" when I am at the end of void start and the response is "True" however I never indicate "Skip_lines = true". I indicated the opposite at the beginning of void start.

I think it can't run because I need to save all lines of datas for the first part, but for the second I use only 1 line / 20. But all lines are saved : and in this second part I indicate that I read all datas which saved in my array.

So I think I have to indicate that I take only 1 line / 20 in the second part and not before.

Is it right ?
I tried to do that before, but I didn't arrive.

Can you help me ?

Thank you for your help ! :)

I found my solution !

Thank you anyway :)

And after the solution made by @Sinisa Hajnal I add to my code a boolean named "Skip_lines" and now my animation is played too slowly.

You can see my update question with this changing.

I'm going to try.

Actually :
- For void start : I want to take all lines of datas from the text file (for my part names //Processing to calculate the acceleration with "Moindres carrés"
- For void FixedUpdate : I need 1 line of data / 20 to play the animation and to store the datas

Do you see what I mean ?

Thank you to want to help me.

I improved my question with my new code.

Do you see where is it my problem ?

Thank you again.

Thank you .

I need so :
if (shouldSkipLines && (counter % 19) != 1)
continue;

But how I indicate in "traitement pour calculer l'accélération" that I want all lines and in "FixedUpdate" that I want only 1 line / 20 ?

I found a solution !

But thank you again :)

I indicate "continue" after "else".

Have you got any other ideas, please ?

Thank you. But it doesn't run.. The code is correct, but when I play the animation, I have the same error message than before : "transform.localPosition assign attempt for 'Left_Elbow' is not valid. Input localPosition is { NaN, NaN, NaN }.
UnityEngine.Transform:set_localPosition(Vector3)"

I have to skip, because otherwise the animation is stopped car it can't to read this data

I have posted a solution.
It runs.

Your solution was very good but there is a problem and I don't arrive to fix it.

Thank you again !

Thanks for your new solution.

But there is a problem :
in : state.speed = speed;
speed in "state.speed" speed is in red...

Ok thank you :)

Thank you very much !
It runs.

But the animation restarts... I assume I make a mistake when I use "animation.Stop".
How can I make a pause ? ( a break in the animation whithout restarting).

Thank you again

Thank you very much ! :D

If I use the debugger at the breakpoint "body[k].transform.position = nv_data[k].positions[i];"

Some items of body[] doesn't exist !
For examples : body[0] exists and from body [1] to body [4] don't exist ! etc ...
Why ? I took the name of GameObject from directly to unity...

And for the string nv_data ... It's disturbing ...
All of value positions are 0 !
But when I used debug.log to see my value positions into the string nv_data (below the lines which allow me to have nv_data.positions) they have so 0 ... But with debug.log we can see positions values of nv_data...

But, for these variables, for their initialization , I did it :
private static Data_struct [] nv_data;
private static GameObject [] body;
"static" allows me to have them in all instances...
So in the debugger, they appear in "static members"
But if I remove "static" nothing changes. There are here again.
So "static" doesn't have any utility here.
I remove it so ?

I'm trying to find the problem, I have added some lines :

void Update () {

for (int i = 0; i < cpt; ++i) {
for (int k = 0; k < body.Length; ++k)
{
if(body == null)
Debug.Log("body is null!");

if(body[k] == null)
Debug.Log("body["+k+"] is null!");

if(body[k].transform == null)
Debug.Log("body["+k+"].transform is null!");

if(nv_data == null)
Debug.Log("nv_data is null!");

if(nv_data[k] == null)
Debug.Log("nv_data["+k+"] is null!");

body[k].transform.position = nv_data[k].positions[i];
Debug.Log(body[1].transform.position);

}
}
}

The errors are :

"body [1] is null !" so my problem is about body[k]
"nv_data is null !" so my problem is about nv_data (it appears when I stop the animation)
"Object reference not set to an instance of an Object" for the line : if(body[k].transform == null)

In generally, we learn swimming with someone who knows how we can do it, no ? During the beginning of the apprenticeship.

And in my case I have to work alone about a purpose which unknown to me.
So, I'm trying to do it and when I was blocked, I asked for help. I thought that was how the forums worked.

Brief, thank you again

Ok, thanks for your all help.

I never thought that this could be bad to ask for help as I did, so thank you again, and my apologies.

So :
My class is : class Data_struct {
My instance is : private Data_struct [] nv_data ;

That's right ?
If it's the case, I have to write :

class Data_struct {

private string nv_data;
public void SetString(string nv_data) { nv_data = nv_data; }
public string GetString() { return nv_data; }
}

Can I call with the same name ?


And I have to call it here ?

void update ()

{

// To associate names_markers to avatar_joints :

GetString(nv_data);

for (int k = 0 ; k < body.Length ; ++k)

body[k].transform.position = nv_data[k].positions[k];



}

Thank you very much

It's exactly this point that I think I'm lost.
When I use a constructor to create an object, I'm creating an instance. But concretely, what is it ?
My instance in my code is
StreamReader reader = new StreamReader ("Suj01_PI_DP_C00_1.txt");
using (reader) {
...
}
?

Thank you again.
I understand what you mean while I'm not english and I begin to understand the structure of c#.
I continue to read websites about this programming while you help me. Some things appear for me more understood than before. So thank you

Thank you;I think I have found a solution thanks to you (of course) !
Actually, I put "private Data_struct [] nv_data ;" after class Data_struct {} so out any function. And I had already removed that in "void start {}".
I didn't have any error now !

But, is that the data entered into nv_Data from " void start {}" are still valid once outside of this function ? Or Nv_data is empty?

I think it's empty. So is there a solution to avoid the destroying, when it's out of the function where it has been completed, of items and datas in nv_Data ?

Thank you again

I put "private Data_struct [] nv_data;" in class Data_struct {}
I have understood that I have to declare this variable not like a local variable. Otherwise, this variable would exist only into the function where it is declared.

When I have said "this doesn't run" means that your solution doesn't a solution for my problem. It's ever the same : nv_data doesn't exist at the current context.

I see what you mean. If I ask specific questions, you want to help me ?

If it's the case : my question would be :
How can I make an animation with a variable which has been declared before, out of my function ("void update ()" in my case) ?

Thank you for the solution and your explanation.
But this doesn't run ...

I had never had any course of the programming. I am in training, and it's not really my role to use the programming but I need it to continue the project.

To be honest I really struggle to understang the programming...

Don't worry about me ;)

I think I need your : using (StreamReader reader = new StreamReader ("Suj01_PI_DP_C00_1.txt"))
{
...
}
But how can I use that in my code ?
I have to erase each "line = reader.Readline ()" ?

Here my new question http://www.codeproject.com/Answers/883314/Csharp-Some-errors-in-void-update#answer2

Sorry, but I'm not english and I don't understand what you want to mean.
Can you explain in a different way please ?

Sorry, again.

In my code it has () already. But when I have copied my code, I have erased "void update ()" sans faire exprès (sorry I'm french and I don't know how we can say this expression).

Actually, my problem is nv_data doesn't exist out "using (reader)". And I don't know how I can fix this problem.

I've just updated my question.

Have you seen my code ?

Thank you for your solution.

But I have discovered it's not that the problem actually.

And I assume that we don't need {} if we have only 1 line which depends of this loop. Is it not exact ?

I have just seen my error...
I have integrated "void update" in "using (reader)" and it's not possible.

I'm going to update my question ...

It's wrote : The name 'k' does not exist in the current context

And that ?

List<myawesomeclass> listOfAwesome = new List<myawesomeclass>();

for(int i = 0; i < names.Length; i++)

{
var myClassVar = new MyAwesomeClass();
myClassVar.name = names[i];
myClassVar.axisX = axes[(i*3)];
myClassVar.axisY = axes[(i*3)+1];
myClassVar.axisZ = axes[(i*3)+2];
myClassVar.dataA = datas[(i*3)];
myClassVar.dataB = datas[(i*3)+1];
myClassVar.dataC = datas[(i*3)+2];
listOfAwesome.Add(myClassVar);

}

It's not possible to use this base for making the code ?

Thank you for what you have made.

But, do you think this code is on track ?

// To define one table and its schema
DataTable dt = new DataTable();
dt.column.Add("Name",typeof(string));
dt.column.Add("Axes",typeof(string));
dt.column.Add("Datas",typeof(string));

// To integrate rows
DataRow dr = dt.NewRow();

for (int i=0; i < names.Length; ++i)
dr["Name"]= names[i];

for (int i=0; i < axes.Length; i=i+3)
dr["Axes"]= axes[i];

for (int i=0; i < datas.Length; i=i+3)
dr["Datas"]= datas[i];

dt.Rows.Add(dr);

It's what I try to do...
And if it's possible, I want to do something with my code because I understand this method.

Thank you a much again

Is it correct to do that ?

class Associating
{
static int main(string[] args)
{
// To define one table and its schema

System.Data.DataTable tdata = new System.Data.DataTable();
tdata.Columns.Add("Name", typeof(string));
tdata.Columns.Add("Axes", typeof(string));
tdata.Columns.Add("Datas", typeof(string));

System.Data.DataRow row = tdata.NewRow();
row["Name"]=
row["Axes"]=
row["Datas"]=
}
}

Thank you for your reply.
I'm a beginner in C#, so I have commented that like I thought it was good to learn for myself. Then, I'm not english, so I try to understand what you mean but it's difficult some times.

Can you give me a simple example, please, to how create a class with a Name, three Axes and three Datas ?

P-s : I'm a (young) girl, so at the beginning Sinisa Hajnal, I don't understand that you spoke about me at your reply.
P-p-s : What is "My 5" ? I don't see it anywhere except in your replys

Do you see my current code ?

I want to gather datas which come from different strings.

For example :

The first data of names is : Suj01:RIAS
The first 3 datas of axes are : X, Y and Z
The first 3 datas of datas are : -242.807816,1106.551270 and 1097.119385

(The same schema for the rest)

I want to gather that :
Suj01:RIAS
X : -242.807816
Y : 1106.551270
Z : 1097.119385
etc ...

The string names has only 1 line with 63 datas
The string axes has only 1 line with (63*3) datas (ever X, Y and Z repeat 3 times each)
The string datas has several lines with (63*3) datas at each line (per line : there is so 63 groups of 3 datas, and each data corresponds to a data from axes, and each group corresponds to a name)

Do you understand what I explain ?

My code runs. I showed only my current program.

And my question is how can I gather these datas ?

ok thank you.

http://www.codeproject.com/Questions/882507/Csharp-Associate-datas-to-other-datas

It takes 1 line / 2 , 2 times and it takes 1 line / 3 etc ...

Your lines about the loop to get only 1 line / 4; doesn't run . So I tried to modify them :
int counter = 0;
while (line != null) {
counter++;
line = reader.ReadLine();
if ((counter %4) == 1)
continue;

It runs but it takes 1 line / 2 or 1 line / 3
I tried to understand why or to modify... But I don't succeed

Anyway, I want to understand.
Thank you very much, again.

About your program, I erased some lines.I think I need this line :
string[] values_position_X_Y_Z = Matrice_Suj01_PI_DP_C00_1.Split(',',3);
It means that we get datas (separated by a coma) and by group of 3 values ?

Thank you very much.
I can verify that "names" show different names.
Now I'm going to verify the other parameters.

Can you continue to help me when I have any problems ?

You are very kind ! You have succeed to give me a good program where I can understand every line. And I knew to bring some add lines to reach my purpose.

Thank you very much !

It corresponds at what I want ?

I have already do this as soon as I saw this problem...
I indicated that like "string[] line" at the beginning

Thank you very much !

I have ever this problem... Line appears in red

I don't know how I can indicate the counter.
Like this ?
int counter %4==0;
line = reader.Readline();
counter %4==1;
while ...

If line is a string, can I use line=reader.Readline ? I think it's correct only if line is an int, no ?
And I can't use string[] axes = line_11.Split(new char[] {'Filed #',','}); because "Split" appears in red.

Oui c'est exact.
La ligne de titre et la ligne de texte "X,Y,Z" sont uniques pour chaque ligne de données. Et c'est bien ces lignes de données dont je veux récupérer 1 ligne sur 4. Donc c'est bien ceci que je dois utiliser (pour prendre 1 ligne sur 4) :
int ligne = Convert.ToInt32(sval[0]);
if (ligne == 1 || ((ligne - 1) % 4) != 0) continue;
?

Merci beaucoup !

First, Thank you a much for your program ! It's very great to help me .

How can I do to indicate that I want to read only 1 line / 4 from the beginning of datas lines ?

Then, there are some mistakes in your program.

For example, we can't use "Split" when the int is a [](array, matrix):
string[] axes = line_11.Split(new char[] {'Filed #',','});
Here "Split" appears in red.

Futhermore, you used the int "line" several times. So, in the program it appears wrong, "line" is red.

I need to don't save the number of the lines.
line = reader.ReadLine(); // here the loop starts getting data
while (line != null) {
// here you're beginning with the lines you need ot enter into the matrix
// (1,-242.807816,1106.551270,1097.119385,14.437944,1075.778687,)
1, -> It's the number of line, and for every line that I save, I have to don't get this number and the ","

Your program allows me to organize every data in group ? For each group of 3 datas, it corresponds to a name "Suj01:RIAS", ... and every data corresponds to a position value ? The first to X, the second to Y and the third to Z ? That in a loop ? Until we have saved every 1 line / 4

Sorry, but I don't have softwares at home for programming. And I have to go... So, I could see your response and your program only Monday.

Thank you a much again.
I hope you understand what I explained in french and in english.
You are very kind !

Say you Monday !

Good weekend

Donc je sauvegarde :
- les noms "Suj01:RIAS" etc : tous les noms qui apparaissent
- 1 ligne / 4 concernant les lignes des données (qui débutent à partir de l'indicateur "1,")

C'est à partir de la ligne "1," que je veux sauvegarder chaque donnée. Sans sauvegarder "1," : la numérotation de la ligne. Pareil pour les suivantes. Cependant, je sauvegarderai uniquement 1 ligne sur 4, par rapport à ces dernières lignes. Mais en tout il doit y avoir 6000 lignes environ. Et par ligne il y a donc : 3*63 données (je crois). Le 3 correspond aux axes X Y Z. Et 63 au nombre de noms différent.

So the old code if it saves : 1,5,9 etc ... it's good for this detail ! If it concerns only datas lines.

I hope that you see what I want to mean

No it's not what I want to mean.

Every datas line begins with :

1,
2,
3,
4,
.
.
.
6580,

These numbers indicate only the number of the datas line. They are not datas about the positions values. It's not usefull. So I want to don't save these things. But I want to save from just after the first ",".
Then, I begin to save 1 line / 4 only from the first datas line.

The lines before the line about "names" , I don't want to save them.
The line about "names" I want to save it full.
The line about "X" "Y" "Z" so we don't need to save, because you used another thing.
The lines about datas : I have to save only 1 line / 4 to begin with the first line which indicates by "1,"

// Add a variable here
int fpsLap = 0;

// The loop
while (true)
{

// values
if ((values = reader.ReadLine()) == null) break;

// only pass 1st time or when rest of integer division = 0
fpsLap++;
if (fpsLap != 1 && ((fpsLap-1) % 4) != 0) continue;

I integrate these lines in the program ? To save 1 line / 4, it's from the beginning of datas lines (positions values). Is it what you had written ? And I need to don't extract "1," ; "2," ; "3,"; ... value concerning the number of datas line.

About the first lines, I don't need to save these informations. I need from the line where there are names "Suj01:RIAS" ... to the end. But before it's not important and I don't need it.

Thank you a much again, and I had to add "system.data", thank you a much for that too.

Your are extraordinary ! Thank you a much ! It's very great that you help me like this.

I'm going to see this solution in more details after my comment.

But, first I see these problems :
- When I copy your program, these sentences appear in red : (everything between '')
System.Data.'DataTable' tdata = new System.Data.'DataTable'();
tdata.'Columns.Add'("Name", typeof(string));
tdata.'Columns.Add'("X", typeof(double));
tdata.'Columns.Add'("Y", typeof(double));
tdata.'Columns.Add'("Z", typeof(double));
System.Data.'DataRow' row = tdata.'NewRow'();
tdata.'Rows.Add'(row);
And the other 'DataRow'

- And I want to take datas in commands line, but after the line number "1," "2," ... How can I write that for the program ?
- Furthermore, I want to take only 1 line / 4 (because the frequency of the file was 100 Fps, but me in Unity I used 25 Fps). I know how I indicate 25 Fps in the program, but how can I write that detail in the program ?

Thank you a much again !!!

Oh yes ! I understand.
It's the same schema .

But in () I don't understand the meaning. Can you explain that please ? I want to understand . I want to delete in my head the programming blur

I don't know if I understand.

Why text 'Suj01:RIAS' are always in the second position of the array ?
This line contains every name of positions, and these positions corresponds to specific values, at the same order they appear

I explained my last paragraph :

At the end, I want, for example for "Suj01:RIAS", concerning the first data line :

__________________Suj01:RIAS_____________________
____X_________________Y________________Z_________
-242.807816______1106.551270_____1097.119385_____

I want data informations for every label "Suj01:RIAS", "Suj01:LIAS", "Suj01:LIPS", ... according to positions values according to the axes "X" "Y" "Z".

I explain exactly what I have to do for my project :
Actually, I have different text files. The lines which interested me are :

Where I want only names like "Suj01:RIAS" "Suj01:LIAS" ...

Where I want positions axes. Every group "X,Y,Z" corresponds to a name like "Suj01:RIAS" ...

I don't copy all datas because there are lots of lines ... And I don't want to take in the array the number of lines, indicates at the begin of every datas line. "1," "2," "3," ... And every data is a position axe. The first : X, the second : Y and the third : Z. For every group (of three datas). And e group corresponds to a name like "Suj01:RIAS" ...

So I have to list. For example :

Suj01:RIAS
X__________Y_____________ Z

-242.807816_1106.551270__1097.119385

Suj01:LIAS
X___________ Y ...

14.437944____1075.778687 ...

...

For every line / 4

And, I know my program is not completed. But I'm blocked, and I really don't know how I can change it to arrive at what I want. And I don't know where it's wrong about what I want. It's for this reason that I explained every command line in comments. But I don't how I can get ahead. I don't know what command line is good, what I have to modify to achieve.

I'm not english so I don't know if I understand exactly what you want to mean.

For making this program, I read different websites to try to understang how I can do this program.

So, here it's what I tried to do. But considering I had never used the programming, so it's very mystic for me even today. I think I don't arrive to understand the concept of C#. So, StreamReader I just understand that it allows me to read my text file.

No, there are several data lines in every text file : approximately 6000. This varies from one file to another.

I think I don't understand your last question.
I am trying to extract values of every data line. (1 line / 4)

If you can to give me a solution at my project, it would be very great !
I'm very lost. I tried to make this programme but I don't know how I can correct myself... I don't see where I did mistakes...

So, if you can to give me a solution, I will be really happy !

Thank you a much in advance.

The problem is I understand what you mean but I don't know how I can use it in this context...

for (int i = 12; i < matrice.Length; i=i+4)
string[] ListLines = new string[+=matrice[i]];
ListLines[i] = reader.ReadLine();

Is that ?

How can I use "loop" ?

Is there another solution ? To tell that I have to repeat this line eleven times
