答
您应该处理菜单项的DropDownOpening事件，然后从列表中删除不需要的项.像这样:
You should handle the DropDownOpening event of the menu item, and remove the unwanted item from the list. Something like this:
MenuStrip ms = new MenuStrip();
ToolStripMenuItem windowMenu = new ToolStripMenuItem("Window");
ms.MdiWindowListItem = windowMenu;
windowMenu.DropDownOpening += (sender, e) =>
{
if (windowMenu.DropDownItems.Count > 0)
windowMenu.DropDownItems.RemoveAt(0);
};
ms.Items.Add(windowMenu);
ms.Dock = DockStyle.Top;
this.MainMenuStrip = ms;
this.Controls.Add(ms);
