WebClient.OnDownloadFileCompleted Method (AsyncCompletedEventArgs)
.NET Framework (current version)
Raises the DownloadFileCompleted event.
Assembly: System (in System.dll)
abstract OnDownloadFileCompleted : e:AsyncCompletedEventArgs -> unit override OnDownloadFileCompleted : e:AsyncCompletedEventArgs -> unit
Parameters
- e
-
Type:
System.ComponentModel.AsyncCompletedEventArgs
An AsyncCompletedEventArgs object containing event data.
Classes that inherit from this class can override this method to perform additional tasks when the DownloadFileCompleted event occurs.
Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.
The OnDownloadFileCompleted 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 OnDownloadFileCompleted in a derived class, be sure to call the base class’s OnDownloadFileCompleted method so that registered delegates receive the event.
