C＃LINQ，如何从数组中获取最大年龄 [英] C# LINQ, how to get max age from array

问题描述

我需要使用LINQ从数组中获得最大年龄。

I need to get maximum age from array with LINQ.

User[] users = new User[5];            //age    
            users[0] = new User("Valod", 20, 4, "Electrik");
            users[1] = new User("Petros", 25, 9, "Hashvapah");
            users[2] = new User("Poghos", 21, 2, "Svarchik");
            users[3] = new User("Hakob", 29, 8, "Hashvapah");
            users[4] = new User("Karen", 32, 12, "Programmer");

我尝试了什么：



我试过这样，但是没有用。

What I have tried:

I tried like this, but it's not working.

var older = from t in users
                        group t by t.age into s
                        select new
                        {
                            users = s.Max(x => x.age)
                        };
            foreach(User items in older)
            {
                Console.WriteLine(items.name);
            }

推荐答案

试试这个：

Try this:

var maxAge = users.Max(x=>x.age) 

尝试：

Try:

User oldest = users.OrderByDescending(u => u.age).FirstOrDefault();
