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；
