        {

            string result = "";

            Str = Str.ToUpper();

            foreach (char value in Str)

            {

                // See if character is in the table.

                if (result.IndexOf(value) == -1)

                {

                result += value;

                }

            }

            return result;

        }

static void Main(string[] args)

        {

            String Name = "Ganga";

            Program obj = new Program();
