Remarks

The OnVerifyingAnswer method is called before the user's answer to the password recovery confirmation question is sent to the membership provider to be verified. The default implementation raises the VerifyingAnswer event.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnVerifyingAnswer method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnVerifyingAnswer(LoginCancelEventArgs) in a derived class, be sure to call the base class's OnVerifyingAnswer(LoginCancelEventArgs) method so that registered delegates receive the event.
