Property Value

A Byte array that contains the downloaded data.

You should check the Error and Cancelled properties before using the data that is returned by this property. If the Error property's value is an Exception object or the Cancelled property's value is true, the asynchronous operation did not complete correctly and the Result property's value will not be valid.

The following code example displays the value of this property.

private static void DownloadDataCallback (Object sender, DownloadDataCompletedEventArgs e)
{
    System.Threading.AutoResetEvent waiter = (System.Threading.AutoResetEvent)e.UserState;

    try
    {
        // If the request was not canceled and did not throw
        // an exception, display the resource.
        if (!e.Cancelled && e.Error == null)
        {
            byte[] data = (byte[])e.Result;
            string textData = System.Text.Encoding.UTF8.GetString (data);

            Console.WriteLine (textData);
        }
    }
    finally
    {
        // Let the main application thread resume.
        waiter.Set ();
    }
}
