构造函数的问题

namespace gouzaohanshu
{
    //构造函数练习：一个是代有参数，另一个是没有传参数；
    public class Person
    {
        public int age;
        public string name;
        //定义方法设置没有参数的
        public Person()
        {
 
        }
        //定义方法有参数的
       public  Person(int age,string name)
        {
           //this是判定这个age是本身的还是传进来的
            this.age = age;
            this.name = name;
        }
    }
    public class TestPerson
    {
        static void Main()
        {
            Person p1 = new Person();
            Person p2 = new Person(3,"xiaoming");
            //注意“”里面的{0}{1}，分别于后面的对应
            Console.WriteLine("Person age:{0},name:{1}",p1.age,p1.name);
            Console.WriteLine("Person age:{0},name:{1}",p2.age,p2.name );
            Console.ReadLine();
        }

    }
