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; }
