我如何对班级中的项目进行排序？ [英] How do I sort items in my class?

问题描述

我班上有学生（我当然是c＃班），每个学生都有自己的考试分数值。

我创建了List并添加了学生+积分那里。我把我的名单写成了最好的学生。

但现在，我想对我的学生进行排序：

1.降序可靠点

- 马克 - 50分

- 大卫 - 40 p

- 罗纳德 - 10 p（仅举例）

2. alphabeticaly



这些线条会是什么样子？



我尝试了什么：



我尝试过类似：var result = students.OrderByDescending（??? => ???）。ToList（）;

或类似：Student.Max（）; - 这看起来不错，但C＃不明白，我想用什么作为我的订单模式..当然：（

解决方案

试试：

  var  result = students.OrderByDescending（s = >  s.Mark）; 

并且：

  var  result = students.OrderByDescending（s = >  s.Name）; 

< blockquote>试试这个

  var  result = students.OrderByDescending（k = >  k.points）.ThenBy（k = >  k.Name）。ToList（） ; 

参考然后通过 [ ^ ]

I´ve got students in my class(I mean c# class of course), each student has got his own point value from exam.
I created List and added Students + points there. I made my List to write best Student.
But now, I want to sort my students:
1. Descending dependable on points
- Mark - 50 points
- David - 40 p
- Ronald - 10 p (just example)
2. alphabeticaly

how would these lines look like?

What I have tried:

I´ve tried something like: var result = students.OrderByDescending(??? => ???).ToList();
or like: Student.Max(); -- this looks great but C# doesn´t understand, what do I want to use as my order pattern.. of course :(

解决方案

Try:

var result = students.OrderByDescending(s => s.Mark);

And:

var result = students.OrderByDescending(s => s.Name);

try this

var result = students.OrderByDescending(k => k.points).ThenBy(k => k.Name).ToList();

refer ThenBy[^]
