Remarks
The MenuItemCollection.SyncRoot property provides a synchronized version of the System.Web.UI.WebControls.MenuItemCollection object that can be used with synchronizing (threading) code.
The MenuItemCollection.IsSynchronized property of this class always returns false, which indicates that the System.Web.UI.WebControls.MenuItemCollection class is not synchronized (not thread safe).
Synchronizing code must perform operations on the MenuItemCollection.SyncRoot object of the System.Web.UI.WebControls.MenuItemCollection collection, not directly on the System.Web.UI.WebControls.MenuItemCollection object itself. This ensures proper operation of collections that are derived from other objects. Specifically, it maintains proper synchronization with other threads that might be simultaneously modifying the System.Web.UI.WebControls.MenuItemCollection object.
The object returned in this implementation is the ArrayList object used to store the System.Web.UI.WebControls.MenuItem objects in the collection.
Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads could still modify the collection, causing the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.
For more information on the MenuItemCollection.SyncRoot property, see the ICollection.SyncRoot property of the ICollection interface.
