WebClient.OnOpenWriteCompleted Method

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Raises the OpenWriteCompleted event.

Namespace: System.Net
Assembly: System.Net (in System.Net.dll)


Protected Overridable Sub OnOpenWriteCompleted ( _
    e As OpenWriteCompletedEventArgs _
protected virtual void OnOpenWriteCompleted(
    OpenWriteCompletedEventArgs e



Classes that inherit from this class can override this method to perform additional tasks when the OpenWriteCompleted event occurs.

Raising an event invokes the event handler through a delegate.

The OnOpenWriteCompleted 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 OnOpenWriteCompleted in a derived class, be sure to call the base class’s OnOpenWriteCompleted method so that registered delegates receive the event.
