关于C#序列化结果的长度获取

    关于C#序列化的文章真的是好多,但是内容大致一样,主要分四类:

  1. BinarySerialize
  2. SoapSerialize
  3. XmlSerialize
  4. JSON.Net和DataContractJsonSerializer

    最近的一个项目需要使用Socket进行通信,所以必然涉及序列化的问题。使用BinarySerialize序列化之后发现无论如何获取不了序列化后的实际长度,代码如下

using System;

using System.Collections.Generic;

using System.Text;

using System.IO;

using System.Runtime.Serialization.Formatters.Binary;



namespace Serialize

{

    public class BinarySerialize

    {

        byte[] buffer=new byte[1024];



        public void Serialize(Book book)

        {

            using (MemoryStream fs = new MemoryStream(buffer, 0,1024))

            {

                BinaryFormatter formatter = new BinaryFormatter();

                formatter.Serialize(fs, book);

            }

        }



        public Book DeSerialize()

        {

            Book book;

            using (MemoryStream fs = new MemoryStream(buffer,0,1024))

            {

                BinaryFormatter formatter = new BinaryFormatter();

                book = (Book)formatter.Deserialize(fs);

            }

            return book;

        }

    }

}

    通过MemoryStream获取长度,永远是1024。后来试了好久发现其实只需要改一点点地方就可以了,改正后的代码如下,顺便做了点通用性扩展:

using System;

using System.Collections.Generic;

using System.Text;

using System.IO;

using System.Runtime.Serialization.Formatters.Binary;





namespace Serialize

{

    public class MemoryBinarySerialize

    {

        

        public static byte[] Serialize(object obj)

        {

            MemoryStream fs = new MemoryStream();

            BinaryFormatter formatter = new BinaryFormatter();

            formatter.Serialize(fs, obj);

            return fs.GetBuffer();

        }

        

        public static object DeSerialize(byte[] data)

        {

            MemoryStream fs = new MemoryStream(data);

            BinaryFormatter formatter = new BinaryFormatter();

            object obj= formatter.Deserialize(fs);

            return obj;

        }

    }

}
