Raises the OpenReadCompleted event.
Assembly: System (in System.dll)
Classes that inherit from this class can override this method to perform additional tasks when the OpenReadCompleted event occurs.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The 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 in a derived class, be sure to call the base class’s method so that registered delegates receive the event.
The following code example shows an implementation of this method that can be customized by a class derived from WebClient.
