合适使用深度拷贝的一个场景包含简单深度拷贝的示例代码

今天有一个场景需要用到对象的复制,写个深度拷贝的代码,做个记录
在同一个业务中包含多处回调的场景下:有一个对象是处理业务逻辑的回调中使用,但是在其他回调函数中会清理这个对象;
出现了一个问题在处理业务逻辑的回调函数中,还没有使用完,其他回调函数清空了这个对象,所有代码中尽量不要用锁,所以不考虑用锁的情况

考虑到主要业务处理回调逻辑比较独立;所以想到了2种方案,

  1. 线程内部对象
  2. 深度拷贝
    因为业务处理回调函数执行时间很短,又没有等待逻辑,所以不合适使用线程池+线程内部对象的方式处理,所以在处理业务逻辑函数入口使用了对象的深度拷贝,保证了函数内部都使用的深度拷贝的对象;
    深度拷贝的示例代码如下,留作备用:
using System;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

namespace DeepCopyExample
{
    [Serializable]
    public class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
        public Address Address { get; set; }

        public Person(string name, int age, Address address)
        {
            Name = name;
            Age = age;
            Address = address;
        }

        public Person DeepCopy()
        {
            using (MemoryStream stream = new MemoryStream())
            {
                BinaryFormatter formatter = new BinaryFormatter();
                formatter.Serialize(stream, this);
                stream.Position = 0;
                return (Person)formatter.Deserialize(stream);
            }
        }
    }

    [Serializable]
    public class Address
    {
        public string City { get; set; }
        public string Country { get; set; }

        public Address(string city, string country)
        {
            City = city;
            Country = country;
        }
    }

    internal class Program
    {
        static void Main(string[] args)
        {
            Address address = new Address("Beijing", "China");
            Person person1 = new Person("duwenlong ", 31, address);
            Person person2 = person1.DeepCopy();
            Console.WriteLine($"Person1 Name: {person1.Name}, Age: {person1.Age}, City: {person1.Address.City}, Country: {person1.Address.Country}");
            Console.WriteLine($"Person2 Name: {person2.Name}, Age: {person2.Age}, City: {person2.Address.City}, Country: {person2.Address.Country}");

            Console.WriteLine("changed Person2 City to Henan");
            person2.Address.City = "Henan";

            Console.WriteLine($"Person1 Name: {person1.Name}, Age: {person1.Age}, City: {person1.Address.City}, Country: {person1.Address.Country}");
            Console.WriteLine($"Person2 Name: {person2.Name}, Age: {person2.Age}, City: {person2.Address.City}, Country: {person2.Address.Country}");

            Console.ReadKey();
        }
    }
}

观察输出Persion2的城市修改了,Persion1的没有变化;
