C# 实现中国象棋【棋盘，棋子】

本文是利用C# 实现中国象棋的棋盘绘制，以及初始化布局，并不实现中国象棋的对弈逻辑。仅供学习参考使用。

思路：

绘制中国象棋棋盘，竖线九条，横线十条。再中间绘制‘楚河’，‘汉界’ 。
绘制棋子，然后将棋子布局在棋盘上即可。

涉及知识点：

用户控件：用于实现棋盘的绘制，重写 OnPaint(PaintEventArgs e) 方法。
Matrix：封装表示几何变换的 3x3 仿射矩阵。本例中主要用于旋转绘制反方的‘汉界’。
GraphicsPath：表示一系列相互连接的直线和曲线。本例中主要用于绘制圆形棋子。

效果图如下：

核心代码

棋盘核心代码如下：

  2         {
  3             base.OnPaint(e);
