You can do like this where your variable s will hold string value

Try this and let me know

When you split string than you will get array and you should access single value by array element as follows


s="1,2,3,4";

string arr[] = s.split(','); 
for(int i =0; i< arr.Length-1;i++)
{
if(arr[i].ToString() == "2")
{
//put your code here if element value is 2
}

}

hope this helps you

Simply use this code-

s="1,2,3,4";

string arr[] = s.split(',');

foreach (string str in arr)
{
   if(str="your value")
    {
     //code
    }
}

Try this and let me know;.
