如何在.net,c#中对用户定义的类进行排序

using System.Linq;

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

List<Person> people = new List<Person>
{
    new Person { Name = "Alice", Age = 30 },
    new Person { Name = "Bob", Age = 25 },
    new Person { Name = "Charlie", Age = 35 }
};

// 按年龄升序排序
var sortedByAgeAscending = people.OrderBy(p => p.Age).ToList();

// 按年龄降序排序
var sortedByAgeDescending = people.OrderByDescending(p => p.Age).ToList();

public class Person : IComparable<Person>
{
    public string Name { get; set; }
    public int Age { get; set; }

    public int CompareTo(Person other)
    {
        return this.Age.CompareTo(other.Age);
    }
}

List<Person> people = new List<Person>
{
    new Person { Name = "Alice", Age = 30 },
    new Person { Name = "Bob", Age = 25 },
    new Person { Name = "Charlie", Age = 35 }
};

// 按年龄升序排序
people.Sort();
