ASP.NET----深浅拷贝问题

浅拷贝是指将对象内的数据完全一致的复制，深拷贝不是这样，它可以将内部的数据按照需要用特殊的方法拷贝，比如说对象内部有一个动态数组，浅拷贝只拷贝指针，而深拷贝可以重新申请空间并将数据复制过来。

看代码：

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

namespace NET.NST.Third.DeepCopy
{
    public class Program
    {
        static void Main(string[] args)
        {
            DeepCopy dc = new DeepCopy();
            dc._i = 10;
            dc._a = new A();
            DeepCopy deepclone = (DeepCopy)dc.Clone();
            DeepCopy shadowclone = (DeepCopy)dc.MemberwiseClone();

            //深拷贝的拷贝对象将拥有自己的引用类型成员对象，
            //所以这里的赋值不会影响原始对象
            deepclone._a._s = "我是深拷贝的A";                                      
            Console.WriteLine(dc);
            Console.WriteLine(deepclone);
            Console.WriteLine("\r\n");

            //浅拷贝的拷贝对象共享原始对象的引用类型成员对象，
            //这里的赋值将影响原始对象
            shadowclone._a._s = "我是浅拷贝的A";                            
            Console.WriteLine(dc);
            Console.WriteLine(shadowclone);
            Console.Read();
        }
    }

    public class DeepCopy : ICloneable
    {
        public int _i = 0;
        public A _a = new A();

        public object Clone()
        {
            //实现深拷贝
            DeepCopy newdc = new DeepCopy();
            newdc._a = new A();
            newdc._a._s = _a._s;
            newdc._i = _i;
            return newdc;
        }

        //实现浅拷贝
        public new object MemberwiseClone()
        {
            return base.MemberwiseClone();
        }
        public override string ToString()
        {
            return "I的值为：" + _i.ToString() + "，A 为：" + _a._s;
        }
    }
    public class A
    {
        public String _s = "我是原始A";
    }
}
