关于C#序列化结果的长度获取

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;
        }
    }
}
