Menu.MenuItemCollection.Add Method (MenuItem)

Adds a previously created MenuItem to the end of the current menu.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

'Declaration
Public Overridable Function Add ( _
	item As MenuItem _
) As Integer

Parameters

item
Type: System.Windows.Forms.MenuItem

The MenuItem to add.

Return Value

Type: System.Int32
The zero-based index where the item is stored in the collection.

A MenuItem can only be contained in one menu at a time, and cannot be added more than once to the same menu. To reuse a MenuItem in more than one menu, use the CloneMenu method of the MenuItem class. To remove a MenuItem that you have previously added, use the Remove method.

This version of the Add method allows you to add previously created MenuItem objects to the end of the menu item collection.

The following code example creates an instance of the derived class, MainMenu, and adds a MenuItem to its collection of MenuItem objects. This example requires that the method defined in this example is located within the class for a form and called by a method in that form class.

Private Sub InitializeMyMainMenu()
     ' Create the MainMenu and the MenuItem to add. 
     Dim mainMenu1 As New MainMenu()
     Dim menuItem1 As New MenuItem("&File")

     ' Use the MenuItems property to call the Add method 
     ' to add the MenuItem to the MainMenu menu item collection. 
     mainMenu1.MenuItems.Add(menuItem1)

     ' Assign mainMenu1 to the form. 
     Me.Menu = mainMenu1
 End Sub
