    class Program
    {
        static void Main(string[] args)

            char[] a = { '1', 'A', '2', 'B', '3', 'C' };
            char[] randomArray = new char[a.Length];
            int randomnumber;

            Random rnd = new Random();
            for (int i = a.Length; i >= 1; i--)
            {
                randomnumber = rnd.Next(1, i + 1) - 1;
                randomArray[i - 1] = a[randomnumber];
                a[randomnumber] = a[i - 1];
            }
            foreach (char s in randomArray)
            {
                Console.Write(s + " , ");
            }
            Console.ReadKey();
