You haven't allocated the (jagged) array you're using. Correct the code like this: String[][] location =null; String sIPAddress=Chennai@tamilnadu@india); int j = 0; rt.Text = string.Empty; location = new string[sIPAddress.Length][]; // Here is allocation of the jagged array for (int i = 0; i { ipvalue = sIPAddress[i].ToString(); locate= getlocate(ipvalue); String[] str = locate.Split('@'); location[i] = new string[str.Length]; // Here is allocation of a row foreach(string place in str) { j = j + 1; location[i][j] = place; } j = 0; } Zoran
