排序算法-C# [英] Sorting Algorithm - C#

问题描述

我有以下未排序列表:

List<string> myUnsortedList = New List<string>();

myUnsortedList.Add("Alpha");
myUnsortedList.Add("(avg) Alpha");
myUnsortedList.Add("Zeta");
myUnsortedList.Add("Beta");
myUnsortedList.Add("(avg) Beta");
myUnsortedList.Add("(avg) Zeta");

我想按字母降序对列表进行排序，然后在正常值后紧跟(avg)来获取值:

I want to sort the list descending alphabetical order, then have the value with (avg) right after the normal value:

最终结果:Zeta，(平均)Zeta，Beta，(平均)Beta，Alpha，(平均)Alpha

Final Result: Zeta, (avg) Zeta, Beta, (avg) Beta, Alpha, (avg) Alpha

我的应用程序是用C#编写的，我想使用LINQ完成排序

My application is written in C# and I want to use LINQ to accomplish the sorting

推荐答案

假设(avg)"是唯一的特殊前缀，这应该可以满足您的需求

This should work ok for what you need, assuming "(avg)" is the only special prefix

这将排序所有不包括(avg)"的字符串，然后按字符串长度排序，这样，带有(avg)"前缀的字符串将排在不带字符串的后面

This will order all the stings descending not including the "(avg) " then it will order by the strings length this way the string with the "(avg)" prefix will come after the one without

var result = myUnsortedList.OrderByDescending(x => x.Replace("(avg) ", "")).ThenBy(x => x.Length);

最终结果:

• Zeta
• (avg)Zeta
• 测试版
• (avg)Beta
• Alpha
• (avg)Alpha
