在C#中,可以通過(guò)實(shí)現(xiàn)ISerializable接口來(lái)自定義序列化過(guò)程。以下是一個(gè)簡(jiǎn)單的示例代碼:

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

[Serializable]
public class CustomObject : ISerializable
{
    public int Id { get; set; }
    public string Name { get; set; }

    public CustomObject() { }

    public CustomObject(int id, string name)
    {
        Id = id;
        Name = name;
    }

    // 實(shí)現(xiàn)ISerializable接口的GetObjectData方法
    public void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        info.AddValue("Id", Id);
        info.AddValue("Name", Name);
    }

    // 自定義的反序列化方法
    public CustomObject(SerializationInfo info, StreamingContext context)
    {
        Id = (int)info.GetValue("Id", typeof(int));
        Name = (string)info.GetValue("Name", typeof(string));
    }
}

public class Program
{
    public static void Main()
    {
        CustomObject obj = new CustomObject(1, "Object1");

        // 序列化對(duì)象
        IFormatter formatter = new BinaryFormatter();
        using (Stream stream = new FileStream("data.bin", FileMode.Create, FileAccess.Write, FileShare.None))
        {
            formatter.Serialize(stream, obj);
        }

        // 反序列化對(duì)象
        using (Stream stream = new FileStream("data.bin", FileMode.Open, FileAccess.Read, FileShare.Read))
        {
            CustomObject deserializedObj = (CustomObject)formatter.Deserialize(stream);
            Console.WriteLine($"Id: {deserializedObj.Id}, Name: {deserializedObj.Name}");
        }
    }
}

在上面的示例中,我們創(chuàng)建了一個(gè)自定義的CustomObject類,并實(shí)現(xiàn)了ISerializable接口。在GetObjectData方法中,我們將需要序列化的數(shù)據(jù)添加到SerializationInfo對(duì)象中。在自定義的反序列化構(gòu)造函數(shù)中,我們獲取SerializationInfo對(duì)象中的數(shù)據(jù)來(lái)重新構(gòu)造對(duì)象。

通過(guò)這種方式,我們可以完全控制對(duì)象的序列化和反序列化過(guò)程,實(shí)現(xiàn)自定義的序列化邏輯。
