c#扫雷游戏

一、C#实现扫雷

1、在form中

BombClass bombClass = new BombClass();

        /*布雷按钮事件*/
        private void initBombBtn_Click(object sender, EventArgs e)
        {
            bombClass.InitBombData();
            bombClass.winHandle = bombPanel.Handle;
            bombPanel.Width = bombClass.Width;
            bombPanel.Height = bombClass.Height;

            bombClass.BombDraw();    //使用方法一画雷盘

            //bombClass.DispBomb();  //使用方法二画雷盘
        }

        /*雷盘的鼠标点击事件：方法一 */
        private void bombPanel_MouseClick(object sender, MouseEventArgs e)
        {
            //获取鼠标点击时的位置
            int row = e.Y / (bombClass.CellSize + 1);
            int column = e.X / (bombClass.CellSize + 1);

            //如果已经点击过了
            if (bombClass.BombDataFlag[row, column] == 1)
                return;

            //可以显示标志
            bombClass.BombDataFlag[row, column] = 1;

            //如果踩到的方格是数字
            if (bombClass.BombData[row, column] > 0)
            {
                ;
            }
            else if (bombClass.BombData[row, column] == BombClass.BombInt)
            {
                bombClass.ShowAllBomb();
                MessageBox.Show("踩到地雷了！");
                return;
            }
            else if (bombClass.BombData[row, column] == 0)
            {
                //bombClass.NullDepthFindFirst(row, column);//深度优先搜索
                bombClass.NullWidthFindFirst(row, column);    //广度优先搜索
            }
            if (bombClass.CheckFinishFirst())
            {
                MessageBox.Show("成功！");
                bombClass.ShowAllBomb();
            }
            else
                bombClass.BombDraw();
            
        }
        

/*扫雷panel重绘事件*/
        private void bombPanel_Paint(object sender, PaintEventArgs e)
        {
            if (bombClass.BombStartFlag)
            {
                if (bombClass.winHandle == null)
                    bombClass.winHandle = bombPanel.Handle;
                bombClass.BombDraw();
            }
            
        }

2、扫雷类
