The GetEnumerator method of the AudienceSiteCollection class returns an enumerator that can iterate through the AudienceSiteCollection.
System.Collections.IEnumerator An enumerator that can be used to iterate through the collection.
The enumerator returned by GetEnumerator does not have exclusive access to the collection; therefore, enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads could 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.
