如何在Linq中订购组结果？

Question

我有以下linq查询,它工作正常.我不确定我是如何订购该组的结果的.

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) }

结果目前由UserId升序排序.我在分数下降之后.

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,比顶一个更容易;)

干杯
