调试C# - 堆栈溢出异常？

Question

下面是我的战舰游戏代码.我一直收到以下错误:

由于StackOverflowException,进程终止..

它一直指向

char[,] Grid = new char[10, 10];

怎么解决这个问题？

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

namespace BattleShip_Jamshid_Berdimuratov
{
class BattleshipBoard
{
    Player p = new Player();
    public void Randomize()
    {
        p.SetGrid(1, 2);
        p.SetGrid(2, 2);
        p.SetGrid(3, 2);
    }

    public void DisplayBoard(char[,] Board)
    {
        int Row;
        int Column;

        Console.WriteLine(" ¦ 0 1 2 3 4 5 6 7 8 9");
        Console.WriteLine("--+--------------------");
        for (Row = 0; Row <= 9; Row++)
        {
            Console.Write((Row).ToString() + " ¦ ");
            for (Column = 0; Column <= 9; Column++)
            {
                Console.Write(Board[Column, Row] + " ");
            }
            Console.WriteLine();
        }

        Console.WriteLine("\n");
    }
}

        try

        Player p = new Player();
        b.Randomize();
        while (p.getHitCount() < 12)
        {
            b.DisplayBoard(p.GetGrid());
            p.AskCoordinates();
        }
        Console.WriteLine("Congratulations, " + name + "! You Win!");
        Console.WriteLine("Thanks for playing BerdShip. Press enter to quit.");
    }
}

}

您的BattleshipBoard对象在构造期间创建一个Player对象,并且您的Player对象在构造期间创建BattleshipBoard.这会来回迭代,直到你溢出堆栈.

致电:

BattleshipBoard b = new BattleshipBoard();

将永远不会返回并导致溢出.
