WebClient.UploadFileCompleted Event

Occurs when an asynchronous file-upload operation completes.

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

public event UploadFileCompletedEventHandler UploadFileCompleted

This event is raised each time an asynchronous file upload operation completes. Asynchronous file uploads are started by calling the UploadFileAsync methods.

The UploadFileCompletedEventHandler is the delegate for this event. The UploadFileCompletedEventArgs 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: UploadFileInBackground2("http://www.contoso.com/fileUpload.aspx", "data.txt")
    public static void UploadFileInBackground2 (string address, string fileName)
    {
        WebClient client = new WebClient ();
        Uri uri = new Uri(address);

        client.UploadFileCompleted += new UploadFileCompletedEventHandler (UploadFileCallback2);

	 // Specify a progress notification handler.
	 client.UploadProgressChanged += new UploadProgressChangedEventHandler(UploadProgressCallback);
        client.UploadFileAsync (uri, "POST", fileName);
        Console.WriteLine ("File upload started.");
    }
