Assembly: mscorlib (in mscorlib.dll)
The default implementation of this method is intended to be overridden by a derived class to perform some action after the collection is cleared.
The default implementation of this method is an O(1) operation.Notes to Implementers: This method allows implementers to define processes that must be performed after deleting all the elements from the underlying System.Collections.Hashtable. By defining this method, implementers can add functionality to inherited methods without having to override all other methods. OnClear is invoked before the standard Clear behavior, whereas OnClearComplete is invoked after the standard Clear behavior.
