我如何在Linq订购小组结果？ [英] How do I order a Group result, in Linq?

问题描述

我有以下linq查询，它工作正常。我不确定我是如何订购组的结果的。

I have the following linq query, which works fine. I'm not sure how i order the group'd result.

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。

the results are currently ordered by UserId ascending. I'm after Score descending.

谢谢：）

推荐答案

只需添加orderby子句;）

Just add the orderby clause ;-)

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 };
