将IOrderedEnumerable排序为任意顺序

using System;
using System.Collections.Generic;
using System.Linq;

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

public class Program
{
    public static void Main()
    {
        List<Person> people = new List<Person>
        {
            new Person { Name = "Alice", Age = 25 },
            new Person { Name = "Bob", Age = 30 },
            new Person { Name = "Charlie", Age = 20 }
        };

        // 按照年龄升序排序
        IOrderedEnumerable<Person> orderedPeople = people.OrderBy(p => p.Age);

        // 按照姓名降序排序
        IOrderedEnumerable<Person> finalResult = orderedPeople.ThenByDescending(p => p.Name);

        foreach (Person person in finalResult)
        {
            Console.WriteLine($"Name: {person.Name}, Age: {person.Age}");
        }
    }
}
