WebClient.OnWriteStreamClosed Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Raises the WriteStreamClosed event.

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


Protected Overridable Sub OnWriteStreamClosed ( _
    e As WriteStreamClosedEventArgs _
protected virtual void OnWriteStreamClosed(
    WriteStreamClosedEventArgs e



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

Raising an event invokes the event handler through a delegate.

The OnWriteStreamClosed 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.

The WriteStreamClosed event is raised each time an asynchronous operation to write a stream is completed. These operations are started by calling one of the OpenWriteAsync methods.

Notes to Inheritors

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