如何使用LINQ /按多个元素排序

using System;
using System.Linq;

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

public class Program
{
    public static void Main(string[] args)
    {
        // 创建一个包含Person对象的集合
        var people = new[]
        {
            new Person { Name = "Alice", Age = 25 },
            new Person { Name = "Bob", Age = 30 },
            new Person { Name = "Charlie", Age = 20 },
            new Person { Name = "David", Age = 25 }
        };

        // 按照年龄升序排序，如果年龄相同则按照姓名升序排序
        var sortedPeople = people.OrderBy(p => p.Age).ThenBy(p => p.Name);

        // 输出排序结果
        foreach (var person in sortedPeople)
        {
            Console.WriteLine($"Name: {person.Name}, Age: {person.Age}");
        }
    }
}
