Gets an object that can be used to synchronize access to the MenuItemCollection object.
Assembly: System.Web (in System.Web.dll)
The property provides a synchronized version of the MenuItemCollection object that can be used with synchronizing (threading) code.
Synchronizing code must perform operations on the object of the MenuItemCollection collection, not directly on the 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 MenuItemCollection object.
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.
