Remarks
A collection wrapper that provides ListChanging and ListChanged events. You can also implement custom behavior by overriding its methods.
This class is designed to support both sets and other collection types. If the underlying collection implements ISet<T>, the Add method avoids firing change notification events if the requested item is already in the set. Regardless of whether the collection is a set, the Remove method also avoids firing any notifications when the requested item is not in the collection.
- Template Parameters
-
T Type of each list item TColl Type of the underlying collection
- Type Constraints
-
TColl : ICollection<T>
