use aggregate

var a = "Memeber Admin SupuerAdmin User";
var z = a.Split(' ').Aggregate((x, y) => x + ", " + y);
System.Console.WriteLine(z);

Eval("RoleName").ToString().Split(' ').Aggregate((x, y) => x + ", " + y); shows red line that expression expected.. – Raheel Ahmed Oct 24 '14 at 15:26

@RaheelAhmed if this solution doesn't work for you then `Eval("RoleName")` isn't returning what you think it does. This works based on what you provided. I would set a temporary variable equal to `Eval("RoleName")` and see what exactly is there. – Michael McGriff Oct 24 '14 at 15:52

Use String.Join to transform an array of strings into a single delimited string.

String.Join(", ", Eval("RoleName"));

I'm not sure on the result type of Eval("RoleName"), but if it is a string[], it will work.

Yes it is string[], but String.Join(", ", Eval("RoleName")); not work – Raheel Ahmed Oct 24 '14 at 15:23
