C#函数（构造函数）的重载

using System;namespace test{    class Program    {        static void Main(string[] args)        {            Cat cat = new Cat();//不含参数的构造方法            Console.WriteLine("姓名是{0}，年龄是{1}",cat.name,cat.age);            Cat cat1 = new Cat("一只猫");//含1个参数的构造方法            Console.WriteLine("姓名是{0}，年龄是{1}", cat1.name, cat1.age);            Cat cat2 = new Cat("又一只猫",18);//含2个参数的构造方法            Console.WriteLine("姓名是{0}，年龄是{1}", cat2.name, cat2.age);        }        class Cat        {            public string name;            public int age;            public Cat() { }            public Cat(string nameValue)            {                name = nameValue;            }            public Cat(string nameValue, int ageValue)            {                name = nameValue;                age = ageValue;            }        }    }}
