(C#) Tower Of Hanoi

Hello again, now, for killing time in holiday,i wrote a program again :) , the program is Tower Of Hanoi. Here sort explanation of Tower Of Hanoi, i took it from Wikipedia:
The Tower of Hanoi or Towers of Hanoi (also known as The Towers of Benares) is a mathematical game or puzzle. It consists of three rods, and a number of disks of different sizes which can slide onto any rod. The puzzle starts with the disks neatly stacked in order of size on one rod, the smallest at the top, thus making a conical shape.
The objective of the puzzle is to move the entire stack to another rod, obeying the following rules:

  • Only one disk may be moved at a time.
  • Each move consists of taking the upper disk from one of the pegs and sliding it onto another rod, on top of the other disks that may already be present on that rod.
  • No disk may be placed on top of a smaller disk.
  • Using recurrence relation, the exact number of moves that this solution requires can be calculated by: 2h − 1

here the code written in C#:

using System;
using System.Collections.Generic;
using System.Text;

namespace Hanoi
    class Program
        static void Main(string[] args)
            int x;
            char from='A', to='B', help='C';

                    Console.Write("  input number of disk: ");
                    x = Int32.Parse(Console.ReadLine());
                catch (FormatException e)
                    x = -10;
            }while(x==-10 || x>10);
            Console.WriteLine("n  from = A, to = B, help = Cn");
            hanoi(x, from, to, help);


        static void hanoi(int x, char from, char to, char help)
            if (x > 0)
                hanoi(x - 1, from, help, to);
                move(x, from, to);
                hanoi(x - 1, help, to, from);


        static void move(int x, char from, char to)
            Console.WriteLine("  move disk "+x+" from "+from+" to "+to);

    try to thinking recursive… :)

  3. hi, just wondering if you have the web forms application for towers of hanoi?

  4. xuan says:

    is there any way of solving hanoi without a recursive algorithm ?

  5. Hanna says:

    thank you :-)

    I saw this article on Code Project, with similar code for you hanoi method and a nice UI done in windows forms. http://www.codeproject.com/Articles/393158/Towers-of-Hanoi
