用c#写一个贪吃蛇代码

好的，以下是一个简单的 C# 贪吃蛇代码示例，您可以参考一下：

using System;
using System.Collections.Generic;

namespace SnakeGame
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.CursorVisible = false;
            Console.SetWindowSize(50, 25);

            // 初始化贪吃蛇
            Snake snake = new Snake(20, 10);

            // 初始化食物
            Food food = new Food();

            while (true)
            {
                // 绘制贪吃蛇和食物
                Console.Clear();
                snake.Draw();
                food.Draw();

                // 移动贪吃蛇和判断是否吃到食物
                if (snake.Move(food))
                {
                    food = new Food();
                }

                // 判断是否游戏结束
                if (snake.IsDead())
                {
                    Console.Clear();
                    Console.WriteLine("Game over!");
                    break;
                }

                // 控制游戏速度
                System.Threading.Thread.Sleep(100);
            }
        }
    }

    // 贪吃蛇类
    class Snake
    {
        private List<Point> body;
        private Direction direction;

        public Snake(int x, int y)
        {
            body = new List<Point>();
            body.Add(new Point(x, y));
            direction = Direction.Right;
        }

        public void Draw()
        {
            Console.ForegroundColor = ConsoleColor.Green;
            foreach (Point point in body)
            {
                Console.SetCursorPosition(point.X, point.Y);
                Console.Write("*");
            }
        }

        public bool Move(Food food)
        {
            // 判断贪吃蛇是否吃到食物
            if (body[0].X == food.X && body[0].Y == food.Y)
            {
                body.Insert(0, new Point(food.X, food.Y));
                return true;
            }

            // 移动贪吃蛇
            for (int i = body.Count - 1; i > 0; i--)
            {
                body[i].X = body[i - 1].X;
                body[i].Y = body[i - 1].Y;
            }

            switch (direction)
            {
                case Direction.Up:
                    body[0].Y--;
                    break;
                case Direction.Down:
                    body[0].Y++;
                    break;
                case Direction.Left:
                    body[0].X--;
                    break;
                case Direction.Right:
                    body[0].X++;
                    break;
            }

            // 判断贪吃蛇是否撞墙或撞到自己
            for (int i = 1; i < body.Count; i++)
            {
                if (body[0].X == body[i].X && body[0].Y == body[i].Y)
                {
                    return false;
                }
            }

            if (body[0].X < 0 || body[0].X >= Console.WindowWidth ||
                body[0].Y < 0 || body[0].Y >= Console.WindowHeight)
            {
                return false;
            }

            return true;
        }

        public bool IsDead()
        {
            return !Move(new Food());
        }

        public void SetDirection(Direction dir)
        {
            if ((int)dir % 2 != (int)direction % 2)
            {
                direction = dir;
            }
        }
    }

    // 食物类
    class Food
    {
        public int X { get; private set; }
        public int Y { get; private set; }

        public Food()
        {
            Random random = new Random();
            X = random.Next(Console.WindowWidth);
            Y = random.Next(Console.WindowHeight);
        }

        public void Draw()
        {
            Console.ForegroundColor = ConsoleColor.Red;
            Console.SetCursorPosition(X, Y);
            Console.Write("@");
        }
    }

    // 坐标点类
    class Point
    {
        public int X { get; set; }
        public int Y { get; set; }

        public Point(int x, int y)
        {
            X = x;
            Y = y;
        }
    }

    // 方向枚举类
    enum Direction
    {
        Up,
        Down,
        Left,
        Right
    }
}

希望这个示例能够帮到您！
