C# Tictatcoe游戏出现故障，无法将字符串添加到右侧网格，有时代码会自动播放

我做了一个Tictatcoe游戏，用一个函数来简化代码，我的函数playx和playo似乎工作不太正常，然后我尝试编辑我的代码，但它也工作不正常，我只是无法在正确的网格中编写代码，有时它会在两个网格中编写第二个代码

using System;

namespace tictactoe
{
    class MainClass
    {
        static string[,] game = new string[3, 3];

        public static void Main(string[] args)
        {

            Console.WriteLine("Welcome to tictactoe,please play enter to play ");

            Console.Clear();
            int n = 0;

            while (n < 9)
            {
                print();
                playx();

如果你看你的照片，你会发现你在第二行游戏[1,0]的地方重复游戏[0,0]。你在第二行重复游戏[2,2]，也在游戏[1,2]的地方

您的函数应该如下所示：

static void print()
{
    Console.WriteLine(game[0, 0] + "|" + game[0, 1] + "|" + game[0, 2]);

    Console.WriteLine(game[1, 0] + "|" + game[1, 1] + "|" + game[1, 2]);

    Console.WriteLine(game[2, 0] + "|" + game[2, 1] + "|" + game[2, 2]);

}

---

您认为看到的错误是因为打印值不正确。这就是为什么你说有时它会在两个网格中写入，而当你在游戏[0,0]和游戏[2,2]中放置一个值时，有时会在这两个网格中写入。

使用调试器并逐步完成代码。这告诉你什么？
