FtpWebRequest Double Login?

I would like to consolidate my code so the 'Login' method is called and the FtpWebRequest would no longer be needed in the 'Upload' method. As is, the FTP server logs show 2 logins. Help!

 
public static FtpWebRequest request = null;

public static bool Login()
        {
            try
            {
                request = (FtpWebRequest) WebRequest.Create(new Uri(_uri));
                request.Credentials = new NetworkCredential(_userName, _password);
                request.Method = WebRequestMethods.Ftp.ListDirectory;
                request.UseBinary = _useBinary;
                request.EnableSsl = _enableSsl;
                request.KeepAlive = _keepAlive;
                request.UsePassive = _usePassive;
                request.Timeout = _timeOut;

                using (var response = (FtpWebResponse) request.GetResponse())
                {
                    statusMessage(response.StatusDescription);
                }
                
                return true;
            }
            catch (Exception)
            {
                return false;
            }
        }

        public static void Upload()
        {
            if (Login())
            {
                try
                {
                    request = (FtpWebRequest) WebRequest.Create(_uri + _fileName);
                    request.Method = WebRequestMethods.Ftp.UploadFile;
                    request.Credentials = new NetworkCredential(_userName, _password);

                    using (var sourceStream = new StreamReader(_filePath + _fileName))
                    {
                        byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd()); 
                        request.ContentLength = fileContents.Length;

                        using (Stream requestStream = request.GetRequestStream())
                        {
                            requestStream.Write(fileContents, 0, fileContents.Length);
                        }
                    }

                    using (var response = (FtpWebResponse) request.GetResponse())
                    {
                        statusMessage(response.StatusDescription);
                    }
                }
                catch (Exception ex)
                {
                    statusMessage(ex.Message);
                }
            }
        }

Why have the Login method at all? You have to send credentials any time you connect to an FTP server. What are you looking to gain?

I want a separate 'response' for login. So if login returns false, I now it was a login failure and not a Upload or Download error.
