绘制多边形（五角星）C#

  //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();

        }
