一个C#中浅复制(shallow copy)/深复制(deep copy)的例子

        [Serializable]        public class User : ICloneable        {            public string name;            public string desc;            public string remark;            public User()            { }            protected User(User u)            {                name = u.name;                desc = u.desc;                remark = u.remark;            }            object ICloneable.Clone()            {                return base.MemberwiseClone();            }            public User Clone()            {                return base.MemberwiseClone() as User;                //return new User(this);            }            public User Clone(bool IsDeepCopy)            {                using (MemoryStream ms = new MemoryStream(1000))                {                    BinaryFormatter bf = new BinaryFormatter(null, new StreamingContext(StreamingContextStates.Clone));                    bf.Serialize(ms, this);                    ms.Seek(0, SeekOrigin.Begin);                    User u = bf.Deserialize(ms) as User;                    ms.Close();                    return u;                }            }            }        public class Guest : User        {            public string IPAddress;            public Guest()            { }            public Guest(User u)                : base(u)            {}            public Guest(Guest g)                : base(g)            {                IPAddress = g.IPAddress;            }        }
