Hanoi Towers - C#

Here I'll show you the issue of Towers of Hanoi code .. Using a recursive way:

namespace HanoiTowers

{

    class Program

    {

        static void Main(string[] args)

        {

            int n;

            do{

                Console.WriteLine("Enter number: ");

                n = Int32.Parse(Console.ReadLine());

            }while(n<=0);

            Hanoi(n, 'A', 'B', 'C');

            Console.ReadLine();

        }

        static void Hanoi(int n, char A, char B, char C)

        {

            if (n == 1)

                Console.WriteLine("{0} --> {1}", A, C);

            else

            {

                Hanoi(n - 1, A, C, B);

                Console.WriteLine("{0} --> {1}", A, C);

                Hanoi(n - 1, B, A, C);

            }

        }

    }

}
