Synchronization of ICollection

Question

When observe the definition of

ICollection extends IEnumerable. It provides size and synchronization members in addition to enumeration.

Does synchronization here represent the synchronization of collection ,when it is shared by multiple threads?.Kindly explain me with simple example how can i practically use "ICollection.IsSynchronized Property".

Thanks.

Answer 1

If IsSynchronized is true, the collection should be thread-safe. However, you still may have to use a lock around multiple list operations (such as finding and index before inserting or whatever) and in this case you can use the SyncRoot property.

Note, however, that both members are only present in the non-generic ICollection interface. The newer (.NET 2) ICollection<T> interface doesn't offer them, and frankly, usually you're going to lock yourself instead of using a synchronized list.
