public RoomClean RoomCleanDateTest2(int id)
{
RoomClean rcc = new RoomClean();
var left = (from rc in db.RoomCleans
join rsr in db.RoomStatusRecords
on rc.StatusID equals rsr.StatusID
into all
from rs in all.DefaultIfEmpty()
where rc.CleanID == id
select new
{
RoomID = rc.RoomID,
StatusID = rc.StatusID
}
).FirstOrDefault();
return rcc ;
}====================================
如何返回RoomClean的类型呢？我试过强制转换的方式不可取
