     static void Main(string[] args)

       CookieContainer cookies = new CookieContainer(); 

       // First send a login request to get the necessary cookies.

       // Second send a request to the Google Voice home page to get a string key needed when placing a callback. 
       HttpWebRequest keyRequest = (HttpWebRequest)WebRequest.Create(GOOGLE_VOICE_HOME_URL);

       StreamReader reader = new StreamReader(keyResponse.GetResponseStream());

       Match rnrMatch = Regex.Match(keyResponseHTML, @"name=""_rnr_se"".*?value=""(?<rnrvalue>.*?)""");

       { 
        Console.WriteLine("Call request failed."); 
       } 
       else

       } 
      } 
      catch (Exception excp) 
      { 
       Console.WriteLine("Exception Main. " + excp.Message); 
      } 
      finally 
      { 
       Console.WriteLine("finished, press any key to exit..."); 
       Console.ReadLine(); 
      } 
     } 
    } 
} 

我已经使用上述代码打电话使用谷歌voicall服务的Googl语音通话，但我收到一个错误。错误是 _rnr_se键没有被发现

pelase告诉这里是什么这个 m_gizmoNumber和_rnr_se关键

登录请求之前加入这一行：

m_cookies.Add(new Uri(PRE_LOGIN_URL), galxResponse.Cookies);
