var ListInOrder = (from f in finaldatelist
               group f by new { f.RoomID, f.RateGroupID } into g
               select g);


成g和select g部分的lambda表达式是什么?

这就是我现在得到的:

 var ListInOrder = finaldatelist.GroupBy(x => x.RoomID, x => x.RateGroupID).Select();

最佳答案

finaldatelist.GroupBy(x => new { x.RoomID, x.RateGroupID });
