Instances of this class are passed to the UploadStringCompletedEventHandler.

The following code example demonstrates asynchronously uploading a string.


    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);
    }



The following method is called when the upload completes.


private static void UploadStringCallback2 (Object sender, UploadStringCompletedEventArgs e)
{
        string reply = (string)e.Result;
        Console.WriteLine (reply);
}
