窗体上应该显示什么文字？

窗体上显示的是 Hello from InstantiateHelloWorld! 吗？为什么？

 

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

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

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

          grfx.DrawString("Hello from InstantiateHelloWorld!", 
                          form.Font, Brushes.Black, 0, 100);
     }
}

很简单的程序，但是有助于理解Paint事件和OnPaint方法，非常有必要把这个问题弄明白。
