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；
