从派生类复制一个基类的内容 [英] Copying the contents of a base class from a derived class

问题描述

我现在有一个派生类的基类。我怎样才能让基类派生类的等于我有一个基类？将浅拷贝工作。

  Base类
 {
私人字符串名称？; 
公共字符串名称{;组; } 
私人字符串的地址; 
公共字符串地址{搞定;组; } 
} 
 
类派生：基本
 {
私人串场; 
公共字符串域{搞定;组; } 
} 
 
命名ConsoleApplication1 
 {
类节目
 {
静态无效的主要（字串[] args）
 { 
基地b =新基地（）; 
 b.Address =Iliff; 
 b.Name =somename; 
 
派生D =新派生的（）; 
 //我怎样才能让基类的ð等于b？ 
 
} 
} 
} 
  

解决方案

如果我理解正确的话，这将工作：

 类派生：基本
 {
 //所有的代码，你有以上，再加上这样的：
 
公共派生（基本toCopy）
 {
 this.name = toCopy.name; 
 this.address = toCopy.address; 
} 
} 
 
派生D =新派生的（B）; 
  

I currently have a derived class and a base class. How can I make the base class of the derived class equal to a base class that I have? Will a shallow copy work?

class Base
{
    private string name; 
    public string Name { get; set; }
    private string address; 
    public string Address { get; set; }
}

class Derived:Base
{
    private string field; 
    public String field { get; set; }
}

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Base b = new Base();
            b.Address = "Iliff";
            b.Name = "somename"; 

            Derived d = new Derived();
            //How can I make the base class of d equal to b ?

        }
    }
}

解决方案

If I understand you correctly, this will work:

class Derived : Base
{
    // all the code you had above, plus this:

    public Derived(Base toCopy)
    {
        this.name = toCopy.name;
        this.address = toCopy.address;
    }
}

Derived d = new Derived(b);
