使用C#写一个贪吃蛇游戏

好的，以下是使用 C# 编写的简单贪吃蛇游戏的代码：

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

namespace SnakeGame
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.SetWindowSize(40, 30); // 设置窗口大小
            Console.CursorVisible = false; // 隐藏光标

            // 初始化地图
            int width = Console.WindowWidth - 1;
            int height = Console.WindowHeight - 1;
            int[,] map = new int[width, height];
            for (int i = 0; i < width; i++)
            {
                map[i, 0] = -1;
                map[i, height - 1] = -1;
            }
            for (int i = 0; i < height; i++)
            {
                map[0, i] = -1;
                map[width - 1, i] = -1;
            }

            // 初始化蛇
            List<int[]> snake = new List<int[]>();

            map[snake[1][0], snake[1][1]] = 2;

            int[] food = GenerateFood(map);

            // 初始化方向
            int direction = 2; // 1：上，2：右，3：下，4：左

            // 游戏循环
            while (true)

}

这是一个简单的贪吃蛇游戏，可以通过上下左右箭头键控制蛇的移动方向，如果蛇撞到墙或者自己，则游戏结束。
