实现十五子游戏

近几来由于工作急需,做三个C#的简要程序。学习了有的基础东西先记下来。

主要有:

壹.生成初叶框架

二.打乱顺序

叁.游戏局地,点击按键后与空白部分沟通的只是Text和Visible部分

  1 const int N = 4;  //行列数
  2 Button[,] buttons = new Button[N, N];
  3 
  4 private void Form1_Load(object sender, EventArgs e)
  5 {
  6     //产生所有按钮
  7     GenerateAllButtons();
  8 }
  9 
 10 private void button1_Click(object sender, EventArgs e)
 11 {
 12     //打乱顺序
 13     Shuffle();
 14 }
 15 
 16 //生成按钮
 17 void GenerateAllButtons()
 18 {
 19     int x0 = 100, y0 = 10, w = 45, d = 50;
 20      for( int row = 0; row < N; row++ )
 21         for ( int col = 0; col < N; col++ )
 22         {
 23             int num = row * N + col;    //数字编号
 24             Button btn = new Button();
 25             btn.Text = (num + 1).ToString();
 26             btn.Top = y0 + row * d;
 27             btn.Left = x0 + col * d;
 28             btn.Width = w;
 29             btn.Height = w;
 30             btn.Visible = true;
 31             btn.Tag = row * N + col;    //button位置
 32 
 33             //注册button点击事件
 34             btn.Click += new EventHandler(btn_Click);
 35 
 36             buttons[row, col] = btn;
 37             this.Controls.Add(btn);
 38         }

 51         Swap(buttons[a, b], buttons[c, d]);
 52     }
 53 }
 54 // 进行游戏
