c# webresponse status

Hello.  New to the Windows world and .NET programming.  Below is a snippet of code (pulled from the internet) that get's a listing of files from an FTP server.  The try/catch code check for the success/failure of the whole operation, but I'd like to get a status from the "WebResponse response = reqFTP.GetResponse();" line of code.  How can I get the status?

Thank you

FtpWebRequest reqFTP;
            try
            {
                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/"));
                reqFTP.UseBinary = true;
                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
                reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;
                WebResponse response = reqFTP.GetResponse();
                
                StreamReader reader = new StreamReader(response.GetResponseStream());
 
                string line = reader.ReadLine();
                while (line != null)
                {
                    result.Append(line);
                    result.Append("\n");
                    line = reader.ReadLine();
                }
                // to remove the trailing '\n'
                result.Remove(result.ToString().LastIndexOf('\n'), 1);
                reader.Close();
                response.Close();
                return result.ToString().Split('\n');
            }
            catch (Exception ex)
            {
                downloadFiles = null;
                Console.WriteLine("Error {0}encountered while getting file list", ex);
                Console.ReadLine();
                return downloadFiles;
                
                
            }
