首先需要进行前台界面的修改

1. 将背景修改成类似打地鼠的背景的图片
2. 将之前Button随机颜色的变化的按钮换成Image控件来放图片
3. 增加一个倒计时随机数

代码：

• 换背景：

  <Window.Background>
          <ImageBrush ImageSource="Img/Bg.png" />
      </Window.Background>

• 禁止窗体放大：

  ResizeMode="CanMinimize"

• 前台图片放的位置采用手动拖动到对应的“洞口”

后台逻辑修改

1. 将之前button随机数list的集合换成Image类生成对应的集合
2. 添加一个倒计时器的DispatcherTimer
3. 计时时执行的程序判断的条件更换
4. 添加右键鼠标事件
5. 修改鼠标按下的状态

代码：

• 在外部声明对象

  List<Image> btns = new List<Image>();
  DispatcherTimer showTimer = new DispatcherTimer();
  DispatcherTimer dispatcherTimer = new DispatcherTimer();
  private int countSecond = 60;
  int score = 0;

• 在启动项目添加随机数集合

  public MainWindow() {
              InitializeComponent();
              btns.Add(btn1);
              btns.Add(btn2);
              btns.Add(btn3);
              btns.Add(btn4);
              btns.Add(btn5);
              btns.Add(btn6);
              btns.Add(btn7);
              btns.Add(btn8);
              btns.Add(btn9);
              btns.Add(btn10);
  }

• 随机数计时器

  Random b1 = new Random();
  int imgNum = b1.Next(btns.Count);
  btns[imgNum].Visibility = Visibility.Visible;
  await Task.Delay(1000);
  btns[imgNum].Visibility = Visibility.Collapsed;
  

• 倒计时计时器

    public void disTimer(object sender, EventArgs e) {
              if (countSecond == 0) {
                  showTimer.Stop();
                  dispatcherTimer.Stop();
                  MessageBox.Show("时间到了游戏结束");
              } else {
                  countSecond--;
                  laSecond.Content = string.Format("倒计时：" + countSecond.ToString());
              }
          }

• 右键点击事件

   private void imgGrid_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) {
              this.Cursor = Application.Current.FindResource("HammerCursor") as Cursor;
              Grid grid = sender as Grid;
              if (grid == null) {
                  return;
              }
              grid.Cursor = Application.Current.FindResource("HmmerCursor") as Cursor;
              if (btn7.Visibility==Visibility.Visible) {
                  if (score < 11) {
                      score++;
                      btn7.Visibility = Visibility.Collapsed;
                      txt.Text = string.Format("得分：" + score.ToString());
                      if (score == 10) {
                          MessageBox.Show("游戏成功");
                      }
                  }
              }else {
                  txt.Text = string.Format("得分：" + score.ToString());
              }
          }
