如何在Linq订购小组成果？

我有以下linq查询，这工作正常。 我不知道我是如何订购集团的结果。

from a in Audits join u in Users on a.UserId equals u.UserId group a by a.UserId into g select new { UserId = g.Key, Score = g.Sum(x => x.Score) } 

结果目前按UserId升序排列。 我在分数下降后。

谢谢 ：）

Answer 1

只需添加orderby子句;-)

 from a in Audits join u in Users on a.UserId equals u.UserId group a by a.UserId into g let score = g.Sum(x => x.Score) orderby score descending select new { UserId = g.Key, Score = score }; 

Answer 2

 var results = (from a in Audits join u in Users on a.UserId equals u.UserId group a by a.UserId into g select new { UserId = g.Key, Score = g.Sum(x => x.Score) }) .OrderByDescending(p=>p.Score); 

希望这会解决你的问题，比顶级的更容易;）

干杯
