通过订购多领域列表（C＃）？ [英] Order a List (C#) by many fields?

问题描述

我想很多领域，不只是一个命令在C＃中的对象的列表。例如，假设我有一个称为X有两个属性，A和B类，我有以下对象，按照这个顺序：

I want to order a List of objects in C# by many fields, not just by one. For example, let's suppose I have a class called X with two Attributes, A and B, and I have the following objects, in that order:

object1 => A = A，b =H结果
Object2的=> A =A，b =C结果
object3 => A =b，b =X 结果
object4 => A =b，b =b

object1 => A = "a", B = "h"
object2 => A = "a", B = "c"
object3 => A = "b", B = "x"
object4 => A = "b", B = "b"

和我想首先为了通过属性列表，当它们等于由b元素，因此为了将是：

and I want to order the list by A attribute first, and when they are equals, by B element, so the order would be:

一，C结果，
中的，h的< BR>
b，b结果
b，X

"a" "c"
"a" "h"
"b" "b"
"b" "x"

据我所知，排序依据法秩序通过一个参数

As far as I know, the OrderBy method order by one parameter.

问：我如何通过多个字段订购C＃列表

Question: How can I order a C# List by more than one field?

非常感谢你。

推荐答案

使用 ThenBy

Customer.OrderBy（C => c.LastName）.ThenBy（C => c.FirstName）
