WebClient.UploadDataCompleted Event

Occurs when an asynchronous data-upload operation completes.

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

public event UploadDataCompletedEventHandler UploadDataCompleted

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

The UploadDataCompletedEventHandler is the delegate for this event. The UploadDataCompletedEventArgs 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.

    public static void UploadDataInBackground3 (string address)
    {
        WebClient client = new WebClient ();
        Uri uri = new Uri(address);
        string text = "Time = 12:00am temperature = 50";
        byte[] data = System.Text.Encoding.UTF8.GetBytes (text);

        client.UploadDataCompleted += new UploadDataCompletedEventHandler (UploadDataCallback3);
        client.UploadDataAsync (uri, data);
    }
