WebClient.DownloadFileCompleted Event

Occurs when an asynchronous file download operation completes.

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

public event AsyncCompletedEventHandler DownloadFileCompleted

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 static void DownLoadFileInBackground2 (string address)
    {
        WebClient client = new WebClient ();
        Uri uri = new Uri(address);

        // Specify that the DownloadFileCallback method gets called 
        // when the download completes.
        client.DownloadFileCompleted += new AsyncCompletedEventHandler (DownloadFileCallback2);
        // Specify a progress notification handler.
        client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(DownloadProgressCallback);
        client.DownloadFileAsync (uri, "serverdata.txt");
    }
