# 贪吃蛇游戏 (Snake Game)一个用C#编写的控制台版贪吃蛇游戏。## 功能特点- 完整的贪吃蛇游戏逻辑
- 使用方向键控制蛇的移动
- 实时分数显示
- 碰撞检测（墙壁和自身）
- 食物随机生成
- 游戏结束统计## 游戏控制- **方向键**: 控制蛇的移动方向
- **ESC键**: 退出游戏## 如何运行### 方法1: 使用 .NET CLI1. 确保您已安装 .NET 6.0 或更高版本
2. 在项目目录中打开命令行
3. 运行以下命令：```bash
# 编译项目
dotnet build# 运行游戏
dotnet run

### 方法2: 使用 Visual Studio1. 打开 `SnakeGame.csproj` 文件
2. 按 F5 运行游戏## 游戏规则1. 使用方向键控制蛇的移动
2. 吃到食物（★）可以增加分数和蛇的长度
3. 避免撞到墙壁或蛇的身体
4. 游戏会一直进行直到撞墙或撞到自己## 系统要求- .NET 6.0 或更高版本
- Windows/Linux/macOS 操作系统
- 支持控制台应用程序的终端## 游戏截图游戏界面包含：
- 边界墙（█）
- 蛇身（■）
- 食物（★）
- 实时分数显示
- 蛇的长度显示享受游戏吧！
