.net -筆記 簡單的操作符重載

這個操作符重載很有意思

class Program
{
static void Main(string[] args)
{
Person person1 = new Person() { Name = "LiLei", Age = 12 };
Person person2 = new Person("HanMeimei", 11);
Person person3 = person1 + person2;
Person person4 = person1 == person2;
Person person5 = 10;
Console.WriteLine($"Name's merge is {person3.Name}\nAge's sum is {person3.Age}");
Console.ReadKey();
}
}

public class Person
{
public Person() { }
public Person(string name, int age)
{
this.Name = name; this.Age = age;
}
public string Name { get; set; }
public int Age { get; set; }
public static Person operator +(Person p1, Person p2)
{
