Initializes a new instance of the Menu.MenuItemCollection class.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
This class requires that you associate the collection with a class that derives from Menu, such as the MainMenu, ContextMenu, or MenuItem class. Since you must specify a menu that is associated with this collection, you cannot create multiple menu item collections and associate them with a menu as needed. In order to switch the menu items associated with a menu, you must clear the collection of items and add the menu items to display to the collection.
