C#基础知识之this关键字介绍

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public Person(string Name, int Age)
    {
        this.Age = Age;
        this.Name = Name;
    }
}

//声明有实现的构造函数
public Person()
{
    this.NAge = 100;
    Console.WriteLine("我是超人！");
}
public Person(int nAge)
{
    Console.WriteLine("超人的年龄{0}", nAge);
}
 //使用this关键字调用了第二个一个参数的构造函数
public Person(int nAge, string strName)
    : this(1)
{
    Console.WriteLine("我是叫{0}的超人，年龄{1}", strName, nAge);
}

Person p = new Person(10,"强子");

超人的年龄1
我是叫强子的超人，年龄10

public class Person
{
    string[] PersonList = new string[10];
    public string this[int param]
    {
        get { return PersonList[param]; }
        set { PersonList[param] = value; }
    }
}

Person person = new Person();
person[0] = "hello";
person[1] = "world";
Console.WriteLine(person[0]);
