FtpWebRequest request = (FtpWebRequest)WebRequest.Create(test.Resoures.ftp_web_request);

// Set the FTP method to execute.

request.Method = WebRequestMethods.Ftp.UploadFile;

// Set the network credentials.

request.Credentials = new NetworkCredential(

test.Properties.Resorces_CREDENTIALS_PASSWORD);

// Copy the contents of the file to the request stream.

sourceStream = new StreamReader(stream);

byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
