Twitter API 1.1 OAuth狀態用戶時間

我試圖將twitter狀態讀入我的Windows應用程序，該應用程序剛開始工作，但在將升級版OAuth升級到1.1後停止工作。這令我很沮喪，因爲我試圖讓它工作一個星期，但我一直無法解決它。現在，我收到錯誤「找不到遠程服務器：410 Gone」。作爲參考，這裏是我的代碼：Twitter API 1.1 OAuth狀態用戶時間

private void Form1_Load(object sender, EventArgs e) 
    { 

     var oauth_consumer_key = "<Consumer Key>"; 
     var oauth_consumer_secret = "<Consumer Secret>"; 
     var oauth_token = "<Access Token>"; 
     var oauth_token_secret = "<Access Token Secret>"; 


     try 
     { 
      //oauth implementation details 
      var oauth_version = "1.0"; 
      var oauth_signature_method = "HMAC-SHA1"; 

      //unique request details 
      var oauth_nonce = Convert.ToBase64String(new ASCIIEncoding().GetBytes(DateTime.Now.Ticks.ToString())); 
      var timeSpan = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc); 
      var oauth_timestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString(); 

      //messsage api details 
      //var status = "Updating status via REST API if this works"; 
      var resource_url = "https://api.twitter.com/1.1/statuses/user_timeline.json"; 

      var screen_name = "cornerstorepos"; 
      var count = "2"; 

      //create oauth signature 
      var baseFormat = "count={7}&oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" + 
          "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&screen_name={6}"; 
      var baseString = string.Format(baseFormat,             
              oauth_consumer_key, 
              oauth_nonce, 
              oauth_signature_method, 
              oauth_timestamp, 
              oauth_token, 
              oauth_version, 
              screen_name, 
              count 
              ); 

      baseString = string.Concat("GET&", Uri.EscapeDataString(resource_url),"&", Uri.EscapeDataString(baseString)); 

      var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_secret),"&",Uri.EscapeDataString(oauth_token_secret)); 

      string oauth_signature; 
      using(HMACSHA1 hasher = new HMACSHA1(ASCIIEncoding.ASCII.GetBytes(compositeKey))) 
      { 
       oauth_signature = Convert.ToBase64String(hasher.ComputeHash(ASCIIEncoding.ASCII.GetBytes(baseString))); 
      } 

      //create request header 
      var headerFormat = "OAuth oauth_consumer_key=\"{0}\", oauth_nonce=\"{1}\", oauth_signature=\"{2}\", oauth_signature_method=\"{3}\"," + 
           " oauth_timestamp=\"{4}\", oauth_token=\"{5}\", oauth_version=\"{6}\""; 


      var authHeader = string.Format(headerFormat, 
              Uri.EscapeDataString(oauth_consumer_key), 
              Uri.EscapeDataString(oauth_nonce), 
              Uri.EscapeDataString(oauth_signature), 
              Uri.EscapeDataString(oauth_signature_method), 
              Uri.EscapeDataString(oauth_timestamp), 
              Uri.EscapeDataString(oauth_token), 
              Uri.EscapeDataString(oauth_version)); 

      //make request 
      ServicePointManager.Expect100Continue = false; 

      //var postBody1 = "screen_name=" + Uri.EscapeDataString(screen_name); 
      //var postBody2 = "count=" + Uri.EscapeDataString(count); 

      //resource_url += "?" + postBody1 + "&" + postBody2; 

      HttpWebRequest request = (HttpWebRequest)WebRequest.Create(resource_url); 
      request.Headers.Add("Authorization",authHeader); 
      request.Method = "GET"; 
      request.ContentType = "application/x-www-form-urlencoded"; 

      WebResponse response = request.GetResponse(); 


      string responseData = new StreamReader(response.GetResponseStream()).ReadToEnd(); 

      XDocument document = XDocument.Parse(responseData, LoadOptions.None); 
      var query = from ex in document.Root.Descendants("status") 
         select new UserStatus 
         { 
          Status = HttpUtility.HtmlDecode(ex.Element("text").Value), 
         }; 
      users = (from u in query.Take(10) where u.Status != "" select u).ToList(); 

      timer.Start(); 
     } 
     catch 
     { 
      return; 
     } 
    }

這將是巨大的幫助，如果任何人能幫助我解決這個錯誤。
