C# 智能AI五子棋（一）

文章描述：这个程序也记不清是什么时候写的了，犹记得那时我还很年轻，偶然从网上看到了这样一个类似的标题（AI五子棋的实现），进去后看到那个是javascript写的，自己转成了C#，这次又拿出来稍微整理了下，很多人会认为这个标题带点噱头，嗯，我曾经也这么认为。当时写完之后，还在想，这是什么智能AI，不就是换了个算法么。再后来仔细想想，这或许就是现在所说的、智能AI的一个最底层或者说最简单的实现思路，对，是思路。

这篇文章一共分文两篇，这篇不会写关于算法什么的，主要把UI（棋盘绘制）以及页面的相关事件写一下。.

开发环境：.NET Framework版本：4.5

开发工具： Visual Studio 2013

实现代码：

 //棋盘大小        static Size boardSize = new Size(800, 800);        //单元格大小        static Size cellSize = new Size(40, 40);        //棋子大小        static Size chessSize = new Size(25, 25);
        int xCellCount = boardSize.Height / cellSize.Height;        int yCellCount = boardSize.Width / cellSize.Width;
        Graphics graphics;        GraphicsState graphicsState;        Pen pen = new Pen(Color.Black); //记录下过的棋子        List<ChessModel> chessList = new List<ChessModel>();

   private void Form_Chess_Load(object sender, EventArgs e)        {            Width = boardSize.Width + 100;            Height = boardSize.Height;            panel_board.Width = boardSize.Width;            panel_board.Height = boardSize.Height;
            Location = new Point((Screen.PrimaryScreen.WorkingArea.Width - Width) / 2, (Screen.PrimaryScreen.WorkingArea.Height - Height) / 2);
            graphics = panel_board.CreateGraphics();            InitData();
        }        private void Form_Chess_Resize(object sender, EventArgs e)        {            if (WindowState == FormWindowState.Minimized)            {                graphicsState = graphics.Save();            }        }        /// <summary>        /// 绘制棋盘        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void panel_board_Paint(object sender, PaintEventArgs e)        {            //绘制横线            for (int i = 1; i < xCellCount; i++)            {                Point pt1 = new Point(cellSize.Width, cellSize.Width * i);                Point pt2 = new Point(boardSize.Width - cellSize.Width, cellSize.Width * i);                graphics.DrawLine(pen, pt1, pt2);            }
            //绘制竖线            for (int i = 1; i < yCellCount; i++)            {                Point pt1 = new Point(cellSize.Height * i, cellSize.Height);                Point pt2 = new Point(cellSize.Height * i, boardSize.Height - cellSize.Height);                graphics.DrawLine(pen, pt1, pt2);            }            if (graphicsState != null)            {                chessList.ForEach(s =>                {                    graphics.DrawImage(s.type ? Properties.Resources.黑棋子 : Properties.Resources.白棋子, s.point.X, s.point.Y, chessSize.Width, chessSize.Height);                });            }        }
        private void SetStatus(int x, int y, bool type)        {            if (type)            {                lb_white_status.Text = string.Format("白棋下在了第{0}行第{1}列", y, x);            }            else            {                lb_black_status.Text = string.Format("黑棋下在了第{0}行第{1}列", y, x);            }        }
        private void Reset()        {            graphics = panel_board.CreateGraphics();            chessList.Clear();            InitData();            graphicsState = null;            panel_board.Refresh();            panel_board_Paint(null, null);        }
  private void btn_min_Click(object sender, EventArgs e)        {            WindowState = FormWindowState.Minimized;        }
        private void btn_close_Click(object sender, EventArgs e)        {            Close();        }
        private void btn_reset_Click(object sender, EventArgs e)        {            Reset();        }

实现效果：

代码解析：棋盘是在Paint事件中动态绘制的，可参考变量boardSize以及cellSize,棋子是添加到资源文件中的两个图片。然后就是最小化后对数据进行还原。
