C#中深度复制和浅度复制详解

using System;
using System.Collections.Generic;
using System.Text;
namespace Test
{
  public class Content
  {
    public int val;
  }
 
  //此处若是深度复制才继承ICloneable接口
  //public class Cloner : ICloneable
  public class Cloner
  {
    public Content MyContent = new Content();
    public Cloner(int newVal)
    {
      MyContent.val = newVal;
    }
 
    //浅度复制
    //使用System.Object.MemberwiseClone()进行浅度复制,使用getCopy方法.
    public object getCopy()
    {
      return MemberwiseClone();  
    }
 
    //深度复制:
    public object clone()
    {
      Cloner clonedCloner = new Cloner(MyContent.val); //此处是实例化一个对象
      return clonedCloner;
    }
  }
}
 
//主函数

{
  class Program
  {
    static void Main(string[] args)
    {
      Cloner mySource = new Cloner(5);
      Cloner myTarget = (Cloner)mySource.getCopy();//深度为cloner
      Console.WriteLine("MyTarget.Mycontent.Val={}",myTarget.MyContent.val);
      mySource.MyContent.val = 2;
      Console.WriteLine("MyTarget.Mycontent.Val={}", myTarget.MyContent.val);
    }
