Create dynamic variable name

Question

Can we create dynamic variable in C#?

I know my below code is threw error and very poor coding. But this code have small logic like create dynamic variable

var name=0; for(i=0;i<10;i++)// 10 means grid length {     name+i=i; }  var xx1=name1; var xx2=name2; var xx3=name3; 

Is it possible in c#? Create dynamic variable in c#? and change the variable name in c#? and concatenate the variable name in c#(like we can concatenate any control id or name)...

Why I need the dynamic variable name (scenario):

var variablename="" var variablename0=No; var variablename1=Yes; var variablename2=No; 

. . .

I have a gridview with multiple rows. And I need assign server side variable to every row. So I need set of variables in server side. the only I can set Text=<%# variablename+rowCount%> for every template field.

This rowCount means every grid row index.

If the grid has 2 rows, Then rowCount values are 0,1,2

Now I need to change the variablename to variablename0,variablename1,variablename2 dynamically for separate row.

Answer 1

C# is strongly typed so you can't create variables dynamically. You could use an array but a better C# way would be to use a Dictionary as follows. More on C# dictionaries here.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;  namespace QuickTest {     class Program     {         static void Main(string[] args)         {             Dictionary<string, int> names = new Dictionary<string,int>();               for (int i = 0; i < 10; i++)             {                 names.Add(String.Format("name{0}", i.ToString()), i);             }              var xx1 = names["name1"];             var xx2 = names["name2"];             var xx3 = names["name3"];         }     } } 

Answer 2

No. That is not possible. You should use an array instead:

name[i] = i; 

In this case, your name+i is name[i].
