爲什麼office 365登錄緩存顯示空值？

嗨，爲什麼office 365登錄緩存顯示空值？

我正在辦公室365登錄訪問日曆，我已經將服務添加到我的項目，它工作正常沒有任何問題，我已清除我的數據庫，並再次運行我無法獲得的項目日曆事件，它是不可訪問的，因爲緩存顯示空值，我又添加了服務，但它仍然顯示緩存的空值，你可以請任何人幫我解決這個問題，我給我下面的代碼。

 UserTokenCache Cache; 

     // constructor 
     public ADALTokenCache(string user) 
     { 
      // associate the cache to the current user of the web app 
      User = user; 
      this.AfterAccess = AfterAccessNotification; 
      this.BeforeAccess = BeforeAccessNotification; 
      this.BeforeWrite = BeforeWriteNotification; 


      // look up the entry in the DB 
      Cache = db.UserTokenCacheList.FirstOrDefault(c => c.webUserUniqueId == User); 
      // place the entry in memory 
      this.Deserialize((Cache == null) ? null : Cache.cacheBits); 
     } 



     AuthorizationCodeReceived = (context) => 
         { 

          var code = context.Code; 

          ClientCredential credential = new ClientCredential(SettingsHelper.ClientId, SettingsHelper.ClientSecret); 
          String UserObjectId = context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value; 

          AuthenticationContext authContext = new AuthenticationContext(SettingsHelper.Authority, new ADALTokenCache(UserObjectId)); 

          authContext.AcquireTokenByAuthorizationCode(code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential, SettingsHelper.AADGraphResourceId); 

          return Task.FromResult(0); 
         },

感謝，
