//先添加Form1_Paint事件 private void Form1_Paint(object sender, PaintEventArgs e)         {             int x, y;             x = y = 100;//偏移值；             Graphics gr = e.Graphics;             Pen p1 = new Pen(Color.Red, 2);             Point[] pt =  {             new Point(0+x,76+y),             new Point(80+x,76+y),             new Point(106+x,0+y),             new Point(130+x, 76+y),             new Point(210+x, 76+y),             new Point(146+x, 124+y),             new Point(170+x,200+y),             new Point(106+x,152+y),             new Point(40+x,200+y),             new Point(66+x,124+y)};             gr.DrawPolygon(p1, pt);//绘制多边形             gr.Dispose();             p1.Dispose();           }运行结果：
