Gets a value indicating whether access to the PersonalizationStateInfoCollection collection is synchronized (thread safe).
Assembly: System.Web (in System.Web.dll)
Property ValueType: System.Boolean
true if access to the collection is synchronized; otherwise, false. The value is always false for PersonalizationStateInfoCollection objects created by the Web Parts control set.
Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads can still modify the collection, which causes 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.
