I thought that might be the case. It's NOT much cleaner, it simply follows the C# philosophy of making the programmer explicitly state their intentions, of assuming the programmer is an idiot.
However, at least it can be done in a similar manner. Thanks for the tip.

streamReader.ReadLine() will return a null if the stream is at end. So, change the if to:
FileInfo fileInfo = new FileInfo(files[i]);
StreamReader streamReader = fileInfo.OpenText();
string line;
do
{
line = streamReader.ReadLine();
<font color="red">if ((line != null) && (line.IndexOf(searchText) != -1))</font>
{
listBox1.Items.Add(line);
}
}
while(line != null);

Thank you!
But now when I try to make the strings upper I get this exception:
"Object reference not set to an instance of an object" 
I sound to me that the upperLine and upperSearchText are not constructed or something like that1!?!??!?? 
Here is the code:
FileInfo fileInfo = new FileInfo(files[i]);
StreamReader streamReader = fileInfo.OpenText();
// Hela raden
string line;
do
{
// Läs nu in rad för rad
line = streamReader.ReadLine();
string upperLine = line.ToUpper();
string upperSearchText = searchText.ToUpper();
// Testa och se om "searchText" finns innuti raden
if (line != null)
{
int ret = upperLine.IndexOf(upperSearchText);
if(ret != -1)
{
listBox1.Items.Add(line);
}
}
}
while(line != null);

You still are trying to access line after ReadLine() and before cheking it for null.

I'm not sure if this will answer your question, because I am not completely sure how deep your design issue is. There is an article written here that sounds similar to this where the user can compile the code they generate. Here is the link in a new window. C# Compiler

normally when minimize an application,the app will disappear from the windows desktop and will place an item at the taskbar!
then how can i avoid it to place an item at the taskbar?
just have a notification icon,when i double-click the notification icon,the application will resume!
thanks!

Add a notify icon to your main form, then on minimize set the ShowInTaskbar property of the main form to false.
In the context menu for the NotifyIcon have an option to set the WindowState of the main form to Restore, and set the ShowInTaskbar property to true again.

thanks.
but what is the meaning of "on minimize"?
does it have on-minimize event?
you said "set the windowstate of the main form to Restore",
does it mean that "this.WindowState=FormWindowState.Normal"?
thanks!

You can e.g play a sound when minimize the app or maximaze..

Sorry, been working too close to Win32 lately. There isn't an on minimize event, but you can create one fairly easily by overriding WndProc.
protected override void WndProc(ref Message m)
{
switch(m.Msg)
{
case 0x0112:
if( m.WParam.ToInt32() == 0xF020 )
{
}
base.WndProc(ref m);
break;
default:
base.WndProc(ref m);
}
}

Oops, yes I did mean that

when i asked the question,i have not think of any methods that you proposed!
to my surprise,it has so many solutions.
maybe i should work hard!
thanks one more time!

Check the NotifyIcon class in .NET, works nice.
Hope this helps.

Another way to check for Minimize is to override the OnResize and check your window state:
protected override void OnResize(System.EventArgs e)
{
if(WindowState==FormWindowState.Minimized)
{
ShowInTaskbar = false;
}
}
Be sure to save off you window placement and size first though. Then all you need to do is override the notification icon Click event and enable your window again.

Geez, any one have a brick wall handy? My head needs to run into it a few times, maybe it'll think of the obvious solution next time
Thanks for the reminder

hello,
when the below line runs it creates the dll in the application's bin\Debug directory. i'm trying to write it to a directory of my choice instead. i posted this last week. did anyone come across how i might do this. i'll post more code if you need it but the example that's basically the same thing i'm doing is at.
http://www.codeproject.com/csharp/cscompiler.asp
compilerResults = codeCompiler.CompileAssemblyFromSource(compilerParamaters, sourceWSProxy);
i've played around with some of the Parameter properties and couldn't get it to work. so maybe i'm just not doing it right. CompilerResults has a PathToAssembly property but that's after the fact.
any help is appreciated. By the way Tom, if you read this good book on C#. we've got 2 copies of it in our office.
thanks

i've tried a couple of things but still doesn't work. or maybe i'm doing something wrong.
i can get it to write to some directory but then the file(dll) that i'm creating loses its COM component qualities. so its no longer considered a dll, although it still has the extension. at least that's the error i get when i go to Add Reference to the newly created dll. i'm attempting to pass the path in as part of the OutputAssembly CompilerParameter.
compilerParamaters.OutputAssembly = File.CreateText(@"C:\WUTemp\" + fileNameAssembly).ToString();
the other thing i've tried is to create it InMemory and then try to write to some directory. this produces the same result. the file is created with the dll extension but its missing the components.
any thoughts??
thanks
Orion

Shouldn't that be, compilerParamaters.OutputAssembly = @"C:\WUTemp\" + fileNameAssembly?
