帮我用c#写一个五子棋的游戏代码

好的，以下是五子棋游戏的 C# 代码实现，供您参考：

using System;

namespace GomokuGame
{
    class Program
    {
        static int[,] Board = new int[15, 15]; // 棋盘
        static bool IsBlack = true; // 判断当前是黑棋还是白棋

        static void Main(string[] args)
        {
            Console.WriteLine("欢迎来到五子棋游戏！");
            Console.WriteLine("黑棋先手，白棋后手。");
            PrintBoard();

            while (true)
            {
                Console.Write(IsBlack ? "黑棋" : "白棋");
                Console.Write("请落子（例如：3,4）：");

                try
                {
                    string input = Console.ReadLine();
                    string[] positions = input.Split(',');

                    int x = int.Parse(positions[0]) - 1;
                    int y = int.Parse(positions[1]) - 1;

                    if (x < 0 || x > 14 || y < 0 || y > 14)
                    {
                        Console.WriteLine("输入的坐标不合法，请重新输入！");
                        continue;
                    }

                    if (Board[x, y] != 0)
                    {
                        Console.WriteLine("该位置已经有棋子了，请重新输入！");
                        continue;
                    }

                    Board[x, y] = IsBlack ? 1 : 2; // 黑棋为1，白棋为2
                    PrintBoard();

                    if (IsWin(x, y))
                    {
                        Console.WriteLine(IsBlack ? "黑棋胜利！" : "白棋胜利！");
                        break;
                    }

                    IsBlack = !IsBlack; // 切换下棋方
                }
                catch
                {

                }
            }

这段代码实现了五子棋游戏的基本功能，包括打印棋盘、落子、判断胜负等。您可以在此基础上进行扩展，实现更多的功能。
