C#实现十五子游戏教程

最近由于工作需要，做一个C#的简单程序。学习了一些基础东西先记下来。

主要有：

1.生成初始框架

2.打乱顺序

3.游戏部分，点击按钮后与空白部分交换的只是Text和Visible部分

const int N = 4; //行列数Button[,] buttons = new Button[N, N];private void Form1_Load(object sender, EventArgs e){  //产生所有按钮  GenerateAllButtons();}private void button1_Click(object sender, EventArgs e){  //打乱顺序  Shuffle();}//生成按钮void GenerateAllButtons(){  int x0 = 100, y0 = 10, w = 45, d = 50;   for( int row = 0; row < N; row++ )    for ( int col = 0; col < N; col++ )    {      int num = row * N + col;  //数字编号      Button btn = new Button();      btn.Text = (num + 1).ToString();      btn.Top = y0 + row * d;      btn.Left = x0 + col * d;      btn.Width = w;      btn.Height = w;      btn.Visible = true;      btn.Tag = row * N + col;  //button位置      //注册button点击事件      btn.Click += new EventHandler(btn_Click);      buttons[row, col] = btn;      this.Controls.Add(btn);    }  buttons[N - 1, N - 1].Visible = false;}void Shuffle(){  Random rnd = new Random();  for (int i = 0; i < 100; i++ )  {    int a = rnd.Next(N);    int b = rnd.Next(N);    int c = rnd.Next(N);    int d = rnd.Next(N);    Swap(buttons[a, b], buttons[c, d]);  }}// 进行游戏private void btn_Click(object sender, EventArgs e){  Button btn = sender as Button;  Button blank = FindHiddenButton();  // 判断是否相邻  if ( IsNeighbor(btn, blank) )  {    Swap(btn, blank);    blank.Focus();  }  // 判断是否完成  if ( ResultIsOk() )  {    MessageBox.Show("OK!");  }}// 查找空白按钮Button FindHiddenButton(){  for (int row = 0; row < N; row++)    for (int col = 0; col < N; col++)    {      if (!buttons[row,col].Visible)      {        return buttons[row, col];      }    }  return null;}// 判断是否相邻bool IsNeighbor(Button btnA, Button btnB){  int a = (int)btnA.Tag;  int b = (int)btnB.Tag;  int r1 = a / N, c1 = a % N;  int r2 = b / N, c2 = b % N;  if ( (r1 == r2 && (c1 == c2 + 1 || c1 == c2 - 1))    || (c1 == c2 && (r1 == r2 + 1 || r1 == r2 - 1)) )    return true;  return false;}//检查是否完成bool ResultIsOk(){  for (int r = 0; r < N; r++)    for (int c = 0; c < N; c++)    {      if (buttons[r, c].Text != (r * N + c + 1).ToString())      {        return false;      }    }  return true;}//交换两个按钮void Swap(Button btna, Button btnb){  string t = btna.Text;  btna.Text = btnb.Text;  btnb.Text = t;  bool v = btna.Visible;  btna.Visible = btnb.Visible;  btnb.Visible = v;}
