“这个"的作用是什么?构造函数中的关键字? [英] What is the function of the "this" keyword in a constructor?

问题描述

我刚才在看 MSDN 的示例代码，偶然发现:

I was looking at sample code from MSDN just now and came accross:

namespace IListSourceCS
{
    public class Employee : BusinessObjectBase
    {
        private string      _id;
        private string      _name;
        private Decimal     parkingId;

        public Employee() : this(string.Empty, 0) {} // <<--- WHAT IS THIS???
        public Employee(string name) : this(name, 0) {}

推荐答案

它使用该签名调用该类中的另一个构造函数.它是根据其他构造函数实现构造函数的一种方式.base 也可用于调用基类构造函数.您必须有一个与此匹配的签名构造函数才能使其工作.

It calls the other constructor in that class with that signature. Its a way of implementing the constructor in terms of other constructors. base can also be used to call the base class constructor. You have to have a constructor of the signature that matches this for it to work.
