这有什么难得        private void button10_Click(object sender, EventArgs e)
        {
            Graphics g = this.panel1.CreateGraphics();
            Pen pen = new Pen(Color.White, 5);
            for (int i = 0; i < 10; i++)
            {
                if (i % 2 == 0)
                {
                    pen.Color = Color.White;
                    g.DrawLine(pen, new Point(5 * i, 0), new Point(5 * i, panel1.Height));
                }
                else
                {
                    pen.Color = Color.Black;
                    g.DrawLine(pen, new Point(5 * i, 0), new Point(5 * i, panel1.Height));
                }
            }
