Menu.MenuItemCollection.AddRange(MenuItem[]) 方法

定义

将以前创建的一组 MenuItem 对象添加到集合。

public:
 virtual void AddRange(cli::array <System::Windows::Forms::MenuItem ^> ^ items);
public virtual void AddRange (System.Windows.Forms.MenuItem[] items);
abstract member AddRange : System.Windows.Forms.MenuItem[] -> unit
override this.AddRange : System.Windows.Forms.MenuItem[] -> unit
Public Overridable Sub AddRange (items As MenuItem())

参数

items
MenuItem[]

表示要添加到集合的菜单项的一组 MenuItem 对象。

示例

下面的代码示例创建一个数组,并将对象从两MenuItem个对象复制到Menu.MenuItemCollection数组中。 然后,该示例将对象的数组MenuItem复制到命名contextMenu1ContextMenu控件集合中。 此示例要求有两MenuItem个对象包含命名和menuItem2命名menuItem1的子菜单项。

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

注解

可以使用方法快速将一组以前创建MenuItem的对象添加到集合中,而不是使用Add该方法手动将每个MenuItem对象添加到集合中。 如果集合已包含 MenuItem 对象,则调用此方法会将新 MenuItem 对象添加到集合末尾。
