Collection<'T>.ClearItems Method ()
Removes all elements from the Collection<'T>.
Assembly: mscorlib (in mscorlib.dll)
Notes to Inheritors:
Derived classes can override this method to change the behavior of the Clear method.
The following code example shows how to derive a collection class from a constructed type of the Collection<'T> generic class, and how to override the protected InsertItem, RemoveItem, ClearItems, and SetItem methods to provide custom behavior for the Add, Insert, Remove, and Clear methods, and for setting the Item property.
The custom behavior provided by this example is a Changed notification event that is raised at the end of each of the protected methods. The Dinosaurs class inherits Collection<string> (Collection(Of String) in Visual Basic) and defines the Changed event, which uses a DinosaursChangedEventArgs class for the event information, and an enumeration to identify the kind of change.
The code example calls several properties and methods of Collection<'T> to demonstrate the custom event.
