软设之后想着休息几天再继续其他课程的学习，于是花了点时间写了一个俄罗斯方块的小游戏(通过网上大神的版本)。俄罗斯方块的游戏主要有两个类组成。一个是方块类，用于创建不同形状的俄罗斯方块，并且提供在界面画方块的方法。还有一个就是游戏类，提供了键盘响应事件以及游戏的判定。

以下是代码：

  1 方块类
  2  public class Blocks
  3     {
  4         private const int blockWidth = 21;
  5         private const int blockHeight = 21;
  6         private int _width;//方块的宽，表示有多少个单元组成
  7         private int _height;//方块的高
  8         private int _left;//方块左边的位置
  9         private int _top;//右边的位置
 10         public int[,] shape;//用于存储方块，0表示无，1表示有
 11         public int Top
 12         {
 13             get { return _top; }
 14             set { _top = value; }
 15         }
 16 
 17         public int Left
 18         {
 19             get { return _left; }
 20             set { _left = value; }
 21         }
 22         public int Height
 23         {
 24             get { return _height; }
 25             set { _height = value; }
 26         }
 27         public int Width
 28         {
 29             get { return _width; }
 30             set { _width = value; }
 31         }
 32         public Blocks()
 33         {
 34             getBlocks();
 35         }
 36         /// <summary>

 42             int randomId= r.Next(1,9);
 43             //int randomId = 1;
 44             switch (randomId)
