[英]NHibernate caching not working for anonymous type
I am trying to get the following query to work: 我正在尝试使以下查询工作:
Session.Linq<FooBar>()
.SetCachable(true)
.SetCacheRegion("foobar")
.Select(x => new Baz(x.Foo, x.Bar))
.ToList();
This works when caching is turned off, but with caching enabled I receive the following exception: 当缓存关闭时,此方法有效,但是启用缓存后,我收到以下异常:
System.InvalidCastException: Unable to cast object of type 'Baz' to type 'System.Object[]'. System.InvalidCastException:无法将类型为“ Baz”的对象转换为类型为“ System.Object []”的对象。
The rest of the stack trace is: 其余堆栈跟踪为:
at NHibernate.Cache.StandardQueryCache.Put(QueryKey key, ICacheAssembler[] returnTypes, IList result, Boolean isNaturalKeyLookup, ISessionImplementor session)
at NHibernate.Loader.Loader.PutResultInQueryCache(ISessionImplementor session, QueryParameters queryParameters, IType[] resultTypes, IQueryCache queryCache, QueryKey key, IList result)
at NHibernate.Loader.Loader.ListUsingQueryCache(ISessionImplementor session, QueryParameters queryParameters, ISet`1 querySpaces, IType[] resultTypes)
at NHibernate.Loader.Loader.List(ISessionImplementor session, QueryParameters queryParameters, ISet`1 querySpaces, IType[] resultTypes)
at NHibernate.Impl.SessionImpl.List(CriteriaImpl criteria, IList results)
Anyone know if this is an NHibernate limitation or am I doing something wrong? 有人知道这是NHibernate的限制还是我做错了什么?
LinqToNHibernate is not a full implementation for querying data. LinqToNHibernate不是用于查询数据的完整实现。
Use CriteriaQuery (about 95% coverage off all that is possible to query), or HQL (100% coverage). 使用CriteriaQuery(覆盖所有可能查询的区域约95%)或HQL(覆盖100%)。
