大哥！！！GraphicsPath path=new GraphicsPath(new Point[]{
              new Point(45,45),
              new Point(145,55),
              new Point(200,150),
              new Point(45,45)},
              new byte[]{
                  (byte)PathPointType.Start,
                  (byte)PathPointType.Bezier,
                  (byte)PathPointType.Bezier,
                  (byte)PathPointType.Bezier,
                  (byte)PathPointType.Line}); 一个4条
一个5条好伐~~~
