可以，你查查”运算符重载“或”操作符重载“。重写int的，这个我觉得不行吧，int是个结构体，就算行，也最好别这样做，引发代码混乱。

using System;

namespace CZF
{
    class Program
    {
        static void Main(string[] args)
        {
            var p1 = new Person { Name = "马云", Age = 56 };
            var p2 = new Person { Name = "马化腾", Age = 53 };

            Console.WriteLine($"{p1.Name}>{p2.Name}:{p1 > p2}");
        }
    }

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

        public int Age
        {
            get; set;
        }

        public static bool operator <(Person a, Person b)
        {
            return a.Age < b.Age;
        }

        public static bool operator >(Person a, Person b)
        {
            return a.Age > b.Age;
        }
    }
}
