If you're using .NET 4.0 (VS 2010) or later try this: string str = String.Join( SalesPlan.Riders); otherwise try: string str = String.Join( SalesPlan.Riders.Select(r => r.ToString()).ToArray());

Hello Friend It's quite simple instead of declaring a string variable inside foreach loop try to declare it outside foreach loop. So that the value will not be replaced because as an when your loop moves a new string str variable is created as per your code. Try following string str=; Foreach(var riderId in SalesPlan.Riders) { str+= riderId+; } Hope that solves your problem. With Regards Vishal Gilbile
