SqlCacheDependecy 命令通知不起作用

Question

我一直试图让 sqlcachedependecy 工作，但它似乎没有工作

我在 web.config 和 global.asa 中得到了正确的设置，但是当我运行这个查询并且从网站内部或外部对数据库进行更改时，缓存的对象没有更新，请有人帮助？我知道这不是因为此查询正在查询视图，因为我使用直接 SqlDependecy 对此进行了测试，并且通知工作正常。

  public IQueryable<VictoryList> GetVictoryList()
   {
                string cacheKey = HttpContext.Current.User.Identity.Name + "victoryCacheKey";
                IQueryable<VictoryList> cachednews = (IQueryable<VictoryList>)HttpContext.Current.Cache.Get(cacheKey);

                if (cachednews == null)
                {

                    var results = from v in _datacontext.ViewVictoryLists
                                  orderby _datacontext.GetNewId()
                                  select new VictoryList
                                  {
                                      MemberID = v.MemberID,
                                      Username = v.Aspnetusername,
                                      Location = v.Location,
                                      DaimokuGoal = v.DaimokuGoal,
                                      PreviewImageID = v.PreviewImageID,
                                      TotalDaimoku = v.TotalDaimoku,
                                      TotalDeterminations = v.TotalDeterminations,
                                      DeterminationID = v.DeterminationID,
                                      DeterminationName = v.DeterminationName
                                  };
                    results = results.ToList().AsQueryable();
                    SqlCacheDependencyAdmin.EnableNotifications(_datacontext.Connection.ConnectionString);
                    SqlCacheDependency dependency =
                     new SqlCacheDependency(_datacontext.GetCommand(results) as SqlCommand);



                    HttpContext.Current.Cache.Insert(cacheKey, results, dependency);

                    return results;
                }
                return cachednews;
   }

根据在msdn 中列出的用于创建通知查询的所述限制...

语句不能引用视图。
