範例

以下程式碼範例建立一個陣列，並將兩個Menu.MenuItemCollection物件的物件複製MenuItem到該陣列中。 接著，範例將物件陣列MenuItem複製到一個命名ContextMenu的控制集合contextMenu1中。 此範例要求有兩個 MenuItem 物件包含名為 menuItem1 和 menuItem2的子選單項目。

private:
   void CopyMyMenus()
   {
      // Create empty array to store MenuItem objects.
      array<MenuItem^>^ myItems = gcnew array<MenuItem^>(
         menuItem1->MenuItems->Count + menuItem2->MenuItems->Count );
      
      // Copy elements of the first MenuItem collection to array.
      menuItem1->MenuItems->CopyTo( myItems, 0 );
      // Copy elements of the second MenuItem collection, after the first set.
      menuItem2->MenuItems->CopyTo( myItems, myItems->Length );
      
      // Add the array to the menu item collection of the ContextMenu.
      contextMenu1->MenuItems->AddRange( myItems );
   }

private void CopyMyMenus()
{
   // Create empty array to store MenuItem objects.
   MenuItem[] myItems = 
      new MenuItem[menuItem1.MenuItems.Count + menuItem2.MenuItems.Count];
   
   // Copy elements of the first MenuItem collection to array.
   menuItem1.MenuItems.CopyTo(myItems, 0);
   // Copy elements of the second MenuItem collection, after the first set.
   menuItem2.MenuItems.CopyTo(myItems, myItems.Length);

   // Add the array to the menu item collection of the ContextMenu.
   contextMenu1.MenuItems.AddRange(myItems);
}

Private Sub CopyMyMenus()
    ' Create empty array to store MenuItem objects.
    Dim myItems(menuItem1.MenuItems.Count + menuItem2.MenuItems.Count) As MenuItem
       
    ' Copy elements of the first MenuItem collection to array.
    menuItem1.MenuItems.CopyTo(myItems, 0)
    ' Copy elements of the second MenuItem collection, after the first set.
    menuItem2.MenuItems.CopyTo(myItems, myItems.Length)
       
    ' Add the array to the menu item collection of the ContextMenu.
    contextMenu1.MenuItems.AddRange(myItems)
End Sub

備註

你可以用方法快速將先前建立MenuItem的物件群組加入集合，而不是用這個MenuItem方法手動把每個Add物件加入集合。 如果集合已經包含 MenuItem 物件，呼叫此方法會將新物件 MenuItem 加入集合的末尾。
