自己看吧！
来自《C# Windows 程序设计》的源码

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

class HelpMenu: Form
{
Bitmap bmHelp;

public static void Main()
{
Application.Run(new HelpMenu());
}
public HelpMenu()
{
Text = "Help Menu";

bmHelp = new Bitmap(GetType(), "HelpMenu.Bighelp.bmp");

Menu = new MainMenu();
Menu.MenuItems.Add("&Help");

MenuItem mi = new MenuItem("&Help");
mi.OwnerDraw = true;
mi.Click += new EventHandler(MenuHelpOnClick);
mi.DrawItem += new DrawItemEventHandler(MenuHelpOnDrawItem);
mi.MeasureItem +=
new MeasureItemEventHandler(MenuHelpOnMeasureItem);

Menu.MenuItems[0].MenuItems.Add(mi);
}
void MenuHelpOnMeasureItem(object obj, MeasureItemEventArgs miea)
{
miea.ItemWidth = bmHelp.Width;
miea.ItemHeight = bmHelp.Height;
}
void MenuHelpOnDrawItem(object obj, DrawItemEventArgs diea)
{
Rectangle rect = diea.Bounds;
rect.X += diea.Bounds.Width - bmHelp.Width;
rect.Width = bmHelp.Width;

diea.DrawBackground();
diea.Graphics.DrawImage(bmHelp, rect);
}
void MenuHelpOnClick(object obj, EventArgs ea)
{
MessageBox.Show("Help not yet implemented.", Text);
}
}
