我有一个数据表，我想在其中显示数据库中的记录，我想为此运行原始SQL查询，但不能这样做。我尝试使用dd.sqlquery，但未进入列表。该错误总是在我尝试运行查询时出现，它显示“ DbRawSqlquery不包含要列出的定义”
public ActionResult LoadData()
{
using (var Ms = new DHIFeedbackEntities2())
{
var feedbacklist = Ms.Database.SqlQuery<string>("select [FeedbackUserName],[FeedBackUserEmailID],[FeedBackComment],[Designation],[Organization],[ContactNo],[City],[FeedBackDate] from [DHIFeedback].[dbo].[FeedBack]").ToList<FeedBack>();
//var feedbacklist=Ms.FeedBacks.SqlQuery("select [FeedbackUserName],[FeedBackUserEmailID],[FeedBackComment],[Designation],[Organization],[ContactNo],[City],[FeedBackDate] from [DHIFeedback].[dbo].[FeedBack]").ToList<FeedBack>();
//var feedbacklist = Ms.FeedBacks.SqlQuery("select [FeedbackUserName],[FeedBackUserEmailID],[FeedBackComment],[Designation],[Organization],[ContactNo],[City],convert(varchar,[FeedBackDate],103) as [FeedBackDate] from [DHIFeedback].[dbo].[FeedBack]").ToList<FeedBack>();
return Json(new { data = feedbacklist }, JsonRequestBehavior.AllowGet);
}
