WebClient.UploadStringCompleted Event

Occurs when an asynchronous string-upload operation completes.

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

public event UploadStringCompletedEventHandler UploadStringCompleted

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

The UploadStringCompletedEventHandler is the delegate for this event. The UploadStringCompletedEventArgs 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 UploadStringInBackground2 (string address)
    {
        WebClient client = new WebClient ();
        Uri uri = new Uri(address);
        string data = "Time = 12:00am temperature = 50";
        client.UploadStringCompleted += new UploadStringCompletedEventHandler (UploadStringCallback2);
        client.UploadStringAsync (uri, data);
    }
