Examples

The following code example creates an array and copies the Menu.MenuItemCollection objects from two MenuItem objects into the array. The example then copies the array of MenuItem objects into the control collection for a ContextMenu named contextMenu1. This example requires that there are two MenuItem objects that contain submenu items named menuItem1 and menuItem2.

C#
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);
}

Remarks

You can use this method to combine MenuItem objects from multiple collections into a single array. This feature enables you to easily combine two or more sets of menu items for use in a ContextMenu or MainMenu.
