DownloadFileCompleted Event

WebClient.DownloadFileCompleted Event

Occurs when an asynchronous file download operation completes.

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

'Declaration
Public Event DownloadFileCompleted As AsyncCompletedEventHandler

This event is raised each time an asynchronous file download operation completes. Asynchronous file downloads are started by calling the DownloadFileAsync methods.

The AsyncCompletedEventHandler is the delegate for this event. The AsyncCompletedEventArgs class provides the event handler with event data.

For more information about handling events, see Consuming Events.

The following code example demonstrates setting an event handler for this event.


		'  Sample call : DownLoadFileInBackground2 ("http:' www.contoso.com/logs/January.txt")
		Public Shared Sub DownLoadFileInBackground2(ByVal address As String)

			Dim client As WebClient = New WebClient()

			'  Specify that the DownloadFileCallback method gets called
			'  when the download completes.
			AddHandler client.DownloadFileCompleted, AddressOf DownloadFileCallback2
			'  Specify a progress notification handler.
			AddHandler client.DownloadProgressChanged, AddressOf DownloadProgressCallback
                        Dim uri as Uri = New Uri(address)
			client.DownloadFileAsync(uri, "serverdata.txt")
		End Sub
