WebClient.OnDownloadDataCompleted Method

Raises the DownloadDataCompleted event.

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

abstract OnDownloadDataCompleted : 
        e:DownloadDataCompletedEventArgs -> unit  
override OnDownloadDataCompleted : 
        e:DownloadDataCompletedEventArgs -> unit


Type: System.Net.DownloadDataCompletedEventArgs

A DownloadDataCompletedEventArgs object that contains event data.

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

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event

The OnDownloadDataCompleted 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 OnDownloadDataCompleted in a derived class, be sure to call the base class’s OnDownloadDataCompleted 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.
