如何在LINQ to Objects中使用Max（）之后选择多个值？ [英] How to select multiple values after using Max() in LINQ to Objects?

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();
