编写一个完整的、可运行的俄罗斯方块(Tetris)游戏在 C# 中,推荐使用 **Windows Forms**(轻量、适合教学/原型)或 **MonoGame / Unity**(专业游戏开发)。考虑到你未指定框架,且要求“项目级实现”,我们将采用 **C# + Windows Forms**(.NET 6/7/8),因为它无需额外引擎、可视化直观、易于调试,同时能完整体现俄罗斯方块的核心逻辑(网格管理、方块旋转、碰撞检测、消行、计分、下落控制等)。
✅ 本实现包含以下核心功能:
- 10×20 标准游戏网格(含隐藏顶行防瞬死)
- 7 种经典 Tetromino(I, O, T, S, Z, J, L),带中心旋转(SRS 简化版)
- 键盘控制:←→↓(移动)、↑(旋转)、空格(硬降)、P(暂停)
- 重力下落(可调速)+ 软降加速
- 碰撞检测(与边界/已落定方块)
- 行消除(单行/双行/三行/四行)+ 消行动画(闪烁)
- 分数系统(基础分 × 等级)、等级提升(每 10 行升 1 级,加快下落)
- 游戏状态管理(开始/暂停/结束/重启)
- 简洁 UI:分数、等级、下一方块预览、游戏区

### ✅ 完整可运行代码(单文件 WinForms 项目)
> 💡 使用方式:新建 .NET 6+ Windows Forms App(`dotnet new winforms -n TetrisGame`),替换 `Program.cs` 和 `Form1.cs`;此处为 **单文件精简版 `Form1.cs`**(主窗体),所有逻辑内聚。

### 🔍 代码解释说明:
1. **架构设计**
- 单窗体 `MainForm` 承载全部逻辑,无外部依赖,适合快速运行。
- `Tetromino` 类封装方块形状、旋转、坐标,使用 `shapes[type][rotation][i]` 存储相对坐标,支持任意旋转。
- `board[x, y]` 是整型二维数组,存储颜色ID(1–7),避免对象引用开销。
2. **核心算法**
- **碰撞检测 `IsCollision()`**:检查是否越界(x<0/x≥10/y≥22)或与已落定方块重叠(仅检查 `y ≥ HiddenRows` 区域)。
- **旋转处理**:每次 `Rotate()` 后立即检测碰撞,失败则 `RotateBack()` —— 实现简易 SRS(Super Rotation System)兼容性。
- **消行逻辑**:从底向上扫描,发现满行则将其上方所有行整体下移(覆盖),顶行清零。
3. **游戏循环与性能**
- `Timer` 驱动主下落(非 `while(true)` 阻塞),间隔随等级动态调整(`Math.Max(50, ...)` 防止过快)。
- 所有绘制通过 `OnPaint` 触发,双缓冲已由 WinForms 默认启用(若需更平滑可手动开启 `DoubleBuffered = true`)。
4. **用户体验细节**
- 空格键「硬降」直落到底并立即结算;
- `P` 键暂停/继续;
- 下一方块预览独立绘制在右侧面板;
- 当前方块以半透明高亮显示,区别于已固定方块。
5. **扩展性提示**
- 如需音效:添加 `System.Media.SoundPlayer` 播放 `.wav`;
- 如需存档:序列化 `score`, `level`, `board` 到 JSON 文件;
- 如需网络对战:引入 SignalR 或 WebSocket,将 `board` 和 `piece` 同步为服务端权威状态。
