C#实现AI五子棋游戏的示例代码
作者：Csharp小记
这篇文章主要为大家详细介绍了C#如何智能AI五子棋游戏中的人工下棋操作以及对应的机器操作，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
文章描述
关于简单的介绍，这篇就不赘述了，主要还是来写一下实际的人工下棋操作以及对应的机器操作的算法处理。
还是先大致说一下算法实现方式，我们之前写的五子棋大部分可能主要是基于机器算法做一个拦截操作，即判断横向、竖向、斜向、反斜向的棋子的数量去直接进行拦截。但是这一篇中主要是使用了一个分配权重的算法，根据权重来匹配我是要去拦截你，还是保持自己的胜利。这个权重可以根据自己的需求适当调整（我也是瞎写的）。
万变不离其宗，无论什么算法，肯定到最后都是根据五子棋的玩法，去解析横竖斜的胜率来进行权衡。
开发环境
.NET Framework版本：4.5
开发工具
Visual Studio 2013

}实现效果
代码解析：自己看代码吧，看懂了就拿来优化下，看不懂就直接下载下来玩玩（除了一个思路引导外，好像也没什么用）
