C# 实现对象深拷贝（序列化方式）

using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
[Serializable]
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public List<string> Hobbies { get; set; } = new List<string>();
}
public static class DeepCopyHelper
{
    public static T DeepCopy<T>(T obj)
    {
        using (var ms = new MemoryStream())
        {
            BinaryFormatter formatter = new BinaryFormatter();
            formatter.Serialize(ms, obj);
            ms.Position = 0;
            return (T)formatter.Deserialize(ms);
        }
    }
}
// 调用示例
public static void TestDeepCopy()
{
    var p1 = new Person { Name = "张三", Age = 25 };
    p1.Hobbies.Add("编程");
    var p2 = DeepCopyHelper.DeepCopy(p1);
    p2.Hobbies.Add("阅读");
    Console.WriteLine($"p1爱好: {string.Join(",", p1.Hobbies)}"); // 编程
    Console.WriteLine($"p2爱好: {string.Join(",", p2.Hobbies)}"); // 编程,阅读
}
