C#版扫雷游戏
知识点：
- 枚举类型的使用
- 当某个方法暂时不想去实现的时候，最好在方法体中写上：throw new NotImplementedException()
- 如何将图片资源引入到项目的属性中去
- 设置控件的大小：pane.Size = new Size(paneWidth,paneHeight);
- 设置控件的位置：pane.Location = new Point(paneLeft,paneTop);
- 事件的动态绑定：pane.MouseDown += pane_MouseDown;
- 如何定义事件并引发事
public delegate void MineSweepedSuccessEventHandler(object sender,EventArgs e);
public event MineSweepedSuccessEventHandler MineSweepedSucces;
Form1（主窗体）代码：
