                request.Method = WebRequestMethods.Ftp.UploadFile;

                // This example assumes the FTP site uses anonymous logon.
                request.Credentials = new NetworkCredential("u6341930", "TPmp45D2");

                // Copy the contents of the file to the request stream.
                StreamReader sourceStream = new StreamReader(fileName.ToString());
                byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
                sourceStream.Close();
                request.ContentLength = fileContents.Length;

                Stream requestStream = request.GetRequestStream();
                requestStream.Write(fileContents, 0, fileContents.Length);
                requestStream.Close();

                FtpWebResponse response = (FtpWebResponse)request.GetResponse();

                Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);

                response.Close();


            }
        }
    }
}
