"select new" 返回值问题
hi all,

我有一个linq 语句：

C# code

        public ? GetSurveyAnswers(int SurveyId)        {            var result = from t1 in ctx.QuestionAnswers                         join t2 in ctx.SurveyQuestions                         on t1.PollId equals t2.Id                         where                            t2.Id == SurveyId                         select new                         {                             Question = t2.Question,                             Answer = t1.Answer,                             Votes = t1.Votes,                         };            return result;        }
