河内的塔楼:将钉子从钉子移动到钉子

扩大我之前的帖子,我仍然在写河内塔.在解释了如何在钉子上画出环之后,我有一个很好的解决方案,我仍然有一个问题,我现在已经摆弄了很长一段时间.

这是我的PegClass:

namespace Towers_Of_Hanoi
{
    class PegClass
    {
        private int pegheight; 
        private int y = 3;
        int[] rings = new int[0];
        public PegClass()
        { 
            //this is the default constructor 
        }
        public PegClass(int height)
        { 
            pegheight = height; 
        }

        // other user defined functions 
        public void AddRing(int size)
        { 
            Array.Resize (ref rings, rings.Length + 2);
            rings[rings.Length - 1] = size;
        }

        public void DrawPeg(int x, int numberOfRings = 0)
        { 
            for (int i = pegheight; i >= 1; i--) 
            {
                string halfRing = new string (' ', i);
                if (numberOfRings > 0) 
                { 
                    if (i <= numberOfRings)
                        halfRing = new string ('-', numberOfRings - i + 1);

                }
                Console.SetCursorPosition(x - halfRing.Length * 2 + i + (halfRing.Contains("-") ? (-i + halfRing.Length) : 0), y);
                Console.WriteLine(halfRing + "|" + halfRing);
                y++;
            }
            if (x < 7) {
                x = 7;
            }
            Console.SetCursorPosition (x - 7, y); //print the base of the peg
            Console.WriteLine("----------------");
        }
    }
}

这是我的主要方法.

namespace Tower_of_hanoi
{
    class Program
    {
        static void Main(string[] args)
        {
            PegClass myPeg = new PegClass(8);
            PegClass myPeg2 = new PegClass(8);
            PegClass myPeg3 = new PegClass(8);
            DrawBoard(myPeg, myPeg2, myPeg3);
            Console.WriteLine ("\t\t\nWelcome to kTowers!");

            while (true) 
            {
                string input = "\nWhat peg do you want to move to commander?";
                Console.WriteLine (input);
                if (input == "2")
                {
                    myPeg.DrawPeg (2);
                }
                Console.ReadLine ();          
            }
        }

        public static void DrawBoard(PegClass peg1,PegClass peg2,PegClass peg3)
        {
            Console.Clear();
            peg1.DrawPeg(20,1);
            peg2.DrawPeg(40,2);
            peg3.DrawPeg(60,4);
        }
    }
}

这是当前的输出:

                |                   |                   |        
                |                   |                   |       
                |                   |                   |      
                |                   |                   |     
                |                   |                  -|-
                |                   |                 --|--
                |                  -|-               ---|---
               -|-                --|--             ----|----
         ----------------    ----------------    ----------------

我的问题仍然是,当被要求提示时,如何将' - '字符从peg移动到peg.我已经尝试了几个小时调整它仍然无法搞清楚.

提前谢谢你,你在外面
