C#之深度复制和浅度复制

深度复制就是引用类型的复制

浅度复制是值类型的复制

例如:

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

using System;
using System.Collections.Generic;
using System.Text;

namespace Test
{
    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);
        }
    }
}
