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:
- BinarySerialize
- SoapSerialize
- XmlSerialize
- 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;}} }
