简单的paint事件处理程序

using System;
 using System.Drawing;
using System.Windows.Forms;

class PaintEvent
{
     public static void Main()
     {
          Form form   = new Form();
          form.Text   = "Paint Event";
          form.Paint += new PaintEventHandler(MyPaintHandler);

          Application.Run(form);
     }
     static void MyPaintHandler(object objSender, PaintEventArgs pea)
     {
          Graphics grfx = pea.Graphics;

          grfx.Clear(Color.Chocolate);
     }
}

注意：覆盖了OnMove方法和OnResize方法。
