C#排序字符串小写和大写字母 [英] C# sorting strings small and capital letters

问题描述

是否存在标准功能，该功能允许我按以下方式对大写字母和小写字母进行排序，否则我应该实现自定义比较器:

Is there a standard functionality which will allow me to sort capital and small letters in the following way or I should implement a custom comparator:

student
students
Student
Students

对于实例:

using System;
using System.Collections.Generic;

namespace Dela.Mono.Examples
{
   public class HelloWorld
   {
      public static void Main(string[] args)
      {
         List<string> list = new List<string>();
         list.Add("student");
         list.Add("students");
         list.Add("Student");
         list.Add("Students");
         list.Sort();

         for (int i=0; i < list.Count; i++)
             Console.WriteLine(list[i]);
      }
   } 
}

它将字符串排序为:

student
Student
students
Students

如果我尝试使用list.Sort(StringComparer.Ordinal)，则排序如下:

If I try to use list.Sort(StringComparer.Ordinal), the sorting goes like:

Student
Students
student
students

推荐答案

您在这些行上是不是有意思

Do you mean something on these lines

List<string> sort = new List<string>() { "student", "Students", "students", 
                                         "Student" };
List<string> custsort=sort.OrderByDescending(st => st[0]).ThenBy(s => s.Length)
                                                         .ToList();

第一个按第一个字符排序，然后按长度排序. 按照我上面提到的模式，它匹配您建议的输出，否则您将执行一些自定义比较器

The first one orders it by the first character and then by the length. It matches the output you suggested by then as per the pattern i mentioned above else you will do some custom comparer
