Gets a value indicating whether access to the NameObjectCollectionBase.KeysCollection is synchronized (thread safe).
Assembly: System (in System.dll)
private abstract IsSynchronized : bool with get private override IsSynchronized : bool with get
Property ValueType: System.Boolean
true if access to the NameObjectCollectionBase.KeysCollection is synchronized (thread safe); otherwise, false. The default is false.
Derived classes can provide their own synchronized version of the NameObjectCollectionBase.KeysCollection using the SyncRoot property. The synchronizing code must perform operations on the SyncRoot of the NameObjectCollectionBase.KeysCollection, not directly on the NameObjectCollectionBase.KeysCollection. 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 NameObjectCollectionBase.KeysCollection object.
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.
