本文介绍了如何在LINQ to Objects中使用Max()之后选择多个值?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有以下LINQ查询:
I have the following LINQ query:
var query =
(from p in obj1
group p by p.objID into g
let totalSum = g.Sum(p => p.ObjPrice)
select new { MyObjectID = g.Key, totalSum })
.Max(g => g.totalSum);
我要选择这两个对象ID,并与最高价格的目标价。我该怎么做?
I want to select both the object id and price of the object with the maximum price. How can I do that?
推荐答案
按降序条款,并呼吁使用命令 FirstOrDefault()
。
Use an order by descending clause and call FirstOrDefault()
.
(from p in obj1
group p by p.objID into g
let totalSum = g.Sum(p => p.ObjPrice)
orderby totalSum descending
select new { MyObjectID = g.Key, totalSum }).FirstOrDefault();
