如何将实例数据复制到现有的类引用中/覆盖现有的类引用？C#

public class MyClass
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public void AssignObject()
{
    MyClass original = new MyClass { Id = 1, Name = "Original" };
    MyClass copy = original; // 直接赋值

    // 修改copy会影响original
    copy.Id = 2;
    Console.WriteLine(original.Id); // 输出: 2
}

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

public class MyClass : ICloneable
{
    public int Id { get; set; }
    public string Name { get; set; }

    public object Clone()
    {
        using (MemoryStream ms = new MemoryStream())
        {
            BinaryFormatter formatter = new BinaryFormatter();
            formatter.Serialize(ms, this);
            ms.Position = 0;
            return formatter.Deserialize(ms);
        }
    }
}

public void DeepCopyObject()
{
    MyClass original = new MyClass { Id = 1, Name = "Original" };
    MyClass copy = (MyClass)original.Clone(); // 深拷贝

    // 修改copy不会影响original
    copy.Id = 2;
    Console.WriteLine(original.Id); // 输出: 1
}

public class MyClass
{
    public int Id { get; set; }
    public string Name { get; set; }

    public MyClass DeepCopy()
    {
        return new MyClass
        {
            Id = this.Id,
            Name = this.Name
        };
    }
}

public void DeepCopyObject()
{
    MyClass original = new MyClass { Id = 1, Name = "Original" };
    MyClass copy = original.DeepCopy(); // 深拷贝

    // 修改copy不会影响original
    copy.Id = 2;
    Console.WriteLine(original.Id); // 输出: 1
}
