Type Parameters


The type of object contained as items in the thread-safe, read-only collection.

The SynchronizedReadOnlyCollection<T> stores data in an IList<T> container and provides an object that can be set and used to synchronize access to the collection so that it is thread safe. The IList<T> container can be recovered using the Items property. The synchronized object can be recovered using the SyncRoot property. It can only be set using one of the constructors that take the syncRoot parameter.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
