C#List< string>按拆分排序 [英] C# List<string> OrderBy Split

问题描述

我试图按拆分后的值对列表进行排序.

I'm trying to just Order a list by the value after a split.

例如，我的数据如下所示.

For example my data looks like this.

Z|2  
A|1

我希望我的列表按拆分后的值排序

I want my list to be order by the value after the split

所以我会得到

A|1  
Z|2  

这是我正在使用的，但出现错误:

This is what i'm using but I get the error:

{输入字符串的格式不正确."}

All = All.OrderBy(s => int.Parse(s.Split('|')[1])).ToList();

任何帮助都会很棒！谢谢！

Any help would be awesome! Thanks!

推荐答案

这将起作用:

All = All.OrderBy(s => int.Parse(s.Split('|').Last())).ToList();

更好的方法是拥有结构化类型的列表，而不是哑字符串的列表.例如，您可能具有Tuple<string, int>的列表，并仅按第二个成员对其进行排序.您还可以将元组放入有序容器中，并自动完成排序.

What would work even better though would be to have a list of a structured type instead of a list of dumb strings. For example, you could have a list of Tuple<string, int> and simply sort it by the second member. You could also put the tuple into an ordered container and have sorting done automatically.
