Thread Safety

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

This implementation does not provide a synchronized (thread-safe) wrapper for a NameObjectCollectionBase.KeysCollection, but derived classes can create their own synchronized versions of the NameObjectCollectionBase.KeysCollection using the SyncRoot property.

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.
