C#按另一个列表排序列表 [英] C# Sorting list by another list

问题描述

我现在有2个列表:

list<string> names;
list<int> numbers;

，我需要根据数字中的值对我的名字进行排序. 我一直在搜索，并且大多数使用x.ID之类的东西，但是我真的不知道该值是多少.所以那行不通.

and I need to sort my names based on the values in numbers. I've been searching, and most use something like x.ID, but i don't really know what that value is. So that didn't work.

有人知道吗?该在ID部分帮助我吗?

Does anyone know, what to do, or can help me out in the ID part?

推荐答案

所以我假设两个列表中的元素都是通过索引关联的.

So i assume that the elements in both lists are related through the index.

names.Select((n, index) => new { Name = n, Index = index })
     .OrderBy(x => numbers.ElementAtOrDefault(x.Index))
     .Select(x => x.Name)
     .ToList();

但是，如果两个列表都相关，我将使用诸如Dictionary<int,string>的另一种收集类型.

But i would use another collection type like Dictionary<int,string> instead if both lists are related insomuch.
