        request.Download(stream);
        return stream;
    }

    private static void SaveStream(System.IO.MemoryStream stream, string saveTo)
    {
        using (System.IO.FileStream file = new System.IO.FileStream(saveTo, System.IO.FileMode.Create, System.IO.FileAccess.Write))
        {
            stream.WriteTo(file);
        }
