Hi Team,

My Question:

How to create existing variable using two string in c# or vb.net?

Example:

My Existing variables are =>

string d1, d2, d3, d4, d5;

d1 = "test1";
d2 = "";
d3 = "test2";
d4 = "test3";
d5 = "";

for (int i = 0; i < 5; i++) 
 {
  if ((d+i) == string.Empty)   // it mean d1, d2, d3, d4, d5.
   {
    (d+i) = "00";
   }
 }

Please give me the solution for my issue.

Not clear. What does it mean, "create a variable"?

The "solution to your issue"? What issue? What you are trying to do does not make any sense. Use an array or List of strings.

As mentioned, use a structure that already supports what you want.

You can't easily do it like that - you can do it under some circumstances, but it gets very, very complicated and isn't something I'd recommend a novice trying (or even looking at how to do it).

Instead, why not use an array?

C#

string[] myStrings = new string[] {"test1", "", "test2", "test3", "");
for (int i = 0; i < myStrings.Length; i++)
   {
   if (myStrings[i] == strings.Empty) 
      {
      myStrings[i] = "00";
      }
   }

Only I'd do this:

C#

string[] myStrings = new string[] {"test1", "", "test2", "test3", "");
for (int i = 0; i < myStrings.Length; i++)
   {
   if (string.IsNullOrWhiteSpace(myStrings[i])) 
      {
      myStrings[i] = "00";
      }
   }

Solution 2

create a list or array then;

C#

List<string> list = new List<string>(){d1, d2, d3, d4, d5};
for(int i =0; i<list.count;i++)
 {
  if (string.IsNullOrEmpty(list[i]))  
   {
    list[i] = "00";
   }
 }
