简单的c#winform象棋游戏(附带源码)

算法源自网络(网络源码连接:http://www.mycodes.net/161/6659.htm)

整体思路：用二维数组构建棋盘每一个数组元素封装为一个picturebox附带若干属性(例如:棋子归属方、棋子的类型)，用一个抽象基类规定基本的棋子移动规则(例如:不能选中空白picturebox、该红方走棋时不能选中蓝方棋子)，具体的棋子单独从基类棋子类派生重写派生类的方法规定其走棋规则，和相应填充picturebox的图片(例如: 炮不能斜着走不能直线吃子，翻山炮必须吃子且移动路径上只能有一个棋子)

窗体所用控件：lable、timer、picturebox
