Try this Code using System; using System.Linq; public class Program { private static Random random = new Random(); public static void Main() { Console.WriteLine(RandomString(3)+ - +random.Next(100999)); } public static string RandomString( int length) { const string chars = ABCDEFGHIJKLMNOPQRSTUVWXYZ ; return new string (Enumerable.Repeat(chars length) .Select(s => s[random.Next(s.Length)]).ToArray()); } }
