Remarks
When a MenuItem is removed from the menu item collection, all subsequent menu items are moved up one position in the collection. You can use this version of the Remove
to remove a specific MenuItem from the collection using a reference to the MenuItem to be removed. If you do not have a reference to the MenuItem that you want to remove, you can use the other version of this method that accepts, as a parameter, an index corresponding to the MenuItem to be removed.
