WebClient.OnOpenReadCompleted Method
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Raises the OpenReadCompleted event.
Assembly: System.Net (in System.Net.dll)
Parameters
- e
- Type: System.Net.OpenReadCompletedEventArgs
A OpenReadCompletedEventArgs object containing event data.
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.
The OnOpenReadCompleted 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 InheritorsWhen overriding OnOpenReadCompleted in a derived class, be sure to call the base class’s OnOpenReadCompleted method so that registered delegates receive the event.
