解决方案二：
看的头晕啊！说说思路吧
解决方案三：
if(l[x,y].b){l[x,y].b=false;}else{boolt=l[x,y].go(x,y);if(!t){label1.Text="错误";}l[x,y].b=true;}就这一段出错，说未将引用应用到实例。思路，棋子基类派生车，马。。。定义对象数组，【9,10】棋盘大小staticqizi[,]l=newqizi[9,10];然后画图，摆棋，把棋子的值赋给对象数组在picturebox里的点击事件里得想，x，y即棋子对象未选中，就选择，选中的就走if(l[x,y].b){l[x,y].b=false;}else{boolt=l[x,y].go(x,y);}
