对象深拷贝问题

关于浅拷贝和深拷贝的区别就不细说了(请参看下面代码).

通常会用到 深拷贝

代码 实现 如下:

 class Program
    {
        static void Main(string[] args)
        {
            Person p = new Person { Name = new Name { FirstName = "Hua", LastName = "Rufus" }, Sex = Sex.Man };
            Person ptemp;
            //ptemp = p; 普通赋值测试
            //ptemp = p.Clone();  浅拷贝
            ptemp = p.DeepClone();
            ptemp.Name.FirstName = "xu";
            ptemp.Name.LastName = "ss";
            ptemp.Sex = Sex.Waman;
            Console.WriteLine(p);
            Console.WriteLine(ptemp);
            Console.Read();
        }
    }

    [Serializable]
    partial class Name
    {
        public string FirstName { get; set; }

        public string LastName { get; set; }

        public override string ToString()
        {
            return string.Format(" {0} {1}", LastName, FirstName);
        }

    }

    [Serializable]
    enum Sex
    {
        Man,
        Waman
    }

    [Serializable]
    partial class Person
    {
        public Name Name { get; set; }

        public Sex Sex { get; set; }

        public override string ToString()
        {
            return string.Format("name:{0} sex:{1}", Name, Sex.ToString());
        }

        public Person Clone()
        {
            return this.MemberwiseClone() as Person;
        }

        public Person DeepClone()
        {
            using (MemoryStream ms=new MemoryStream())
            {
                IFormatter formatter = new BinaryFormatter();
                formatter.Serialize(ms, this);
                ms.Seek(0, SeekOrigin.Begin);
                return formatter.Deserialize(ms) as Person;                
            }
        }

       
    }

主要代码:

 using (MemoryStream memory=new MemoryStream())
            {
                IFormatter formatter = new BinaryFormatter();
                formatter.Serialize(memory, this);
                memory.Seek(0, SeekOrigin.Begin);
                return formatter.Deserialize(memory);
            }

 还有一种方法 实现 深拷贝 (反射)http://www.codeproject.com/Articles/3441/Base-class-for-cloning-an-object-in-C

不过 这种方法太绕..而且只实现了 IList IDictionary 这种 内置类型
