.NET怎么将一个对象深度克隆

using System;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

public static T DeepClone<T>(T obj)
{
    if (obj == null) return default(T);

    using (var ms = new MemoryStream())
    {
        var formatter = new BinaryFormatter();
        formatter.Serialize(ms, obj);
        ms.Position = 0;
        return (T)formatter.Deserialize(ms);
    }
}

using System.Text.Json;

public static T DeepCloneJson<T>(T obj)
{
    var json = JsonSerializer.Serialize(obj);
    return JsonSerializer.Deserialize<T>(json);
}

public class Person : ICloneable
{
    public string Name { get; set; }
    public Address Address { get; set; }

    public object Clone()
    {
        var clone = new Person
        {
            Name = this.Name,
            Address = this.Address?.Clone() as Address // 假设 Address 也实现了 Clone
        };
        return clone;
    }
}

public class Address : ICloneable
{
    public string City { get; set; }

    public object Clone() => new Address { City = this.City };
}

Install-Package FastDeepCloner

var clonedObj = DeepCloner.Clone(originalObj);
