在label中画一条线如何就画不上呢

在label中画一条线怎么就画不上呢
代码如下

C# code

Graphics g = label1.CreateGraphics();            Pen p = new Pen(Color.Red, 1);            p.DashStyle = DashStyle.Solid;            g.DrawLine(p, 0, 0, 5, 5);            g.Dispose();

C# code

        private void label1_Paint(object sender, PaintEventArgs e)        {            e.Graphics.DrawLine(Pens.Red, new Point(0, 5), new Point(10, 5));        }
[解决办法]
在label的paint事件中完成
private void label1_Paint(object sender, PaintEventArgs e)
{
   Pen p = new Pen(Color.Red, 1);
   p.DashStyle = DashStyle.Solid;
   e.Graphics.DrawLine(p, 0, 0, 5, 5);
   e.Dispose();
}
