winform 五子棋

半年前写过一个winform小游戏五子棋，比较粗糙，页面如下：

代码结构如下：

ok. 入口程序Program.cs代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;namespace WindowsFormsApp1
{// 游戏状态public enum State{PUT_WTITE, PUT_BLACK, FINISH,}public static class Program{//const int state = 0; // 0 : 未开始  1： 已开始  2：结束public static State state = State.FINISH;public static Form1 form = null;// 字典，表示棋盘状态，所有的棋子：public static Dictionary<string, int> dic = new Dictionary<string, int>(); // key: 棋子横坐标_纵坐标  value: 1:白棋, 2:黑棋/// <summary>/// 应用程序的主入口点。/// </summary>[STAThread]static void Main(){Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);Application.Run(form = new Form1());// Console.WriteLine("state: " + state);}}
}

常量Constant.cs代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace WindowsFormsApp1
{class Constant{public const int size = 11; // 棋盘大小 11 X 11public const int range = 15; // 棋盘中每个棋子的点击范围，鼠标在这个范围就可以把棋子放在这个地方。public const int QI_RADIUS = 10; // 棋盘中的棋子半径public const int paddingEdge = 30; // 棋盘间距public const int writeQi = 1;public const int blackQi = 2;public const int MAX_WEIGHT = 9; // 计算分数的各种场景的权重中， 直接能赢是最大权重。即10的9次方的分数。}
}

页面是拖控件生成的，左边部分绘制棋盘和棋子，右边显示一些信息，以及有一些控制按钮，如下：

ok. 这个类代码量庞大，不赘述，资源已上传。主要是页面的绘制，以及游戏逻辑。其中还加入了AI， 支持人机对战。AI遍历整个棋盘，给每个位置落子计算分数值，用以判断在哪个位置落子最佳。我现在已经下不过AI了。缺点：刷新绘制棋盘时会闪烁，页面也比较粗糙，没有音效。
