序列化悍将Protobuf-Net，入门动手实录

浏览数：18 / 时间：2015年06月09日

最近在研究web api 2，看了一篇文章，讲解如何提升性能的，

技术分享

在序列化速度的跑分中，Protobuf一骑绝尘，序列化速度快，性能强，体积小，所以打算了解下这个利器

1：安装篇

谷歌官方没有提供.net的实现，所以在nuget上找了一个移植的

技术分享

Nuget里搜索Protobuf-net，下载，自动添加到项目中

2：定义数据结构

using ProtoBuf;

namespace ConsoleApplication1
{
    [ProtoContract]
    class Person
    {
        [ProtoMember(1)]
        public int Id { get; set; }
        [ProtoMember(2)]
        public string Name { get; set; }
        [ProtoMember(3)]
        public Address Address { get; set; }
    }
    [ProtoContract]
    class Address
    {
        [ProtoMember(1)]
        public string Line1 { get; set; }
        [ProtoMember(2)]
        public string Line2 { get; set; }
    }
}

3：封装简单操作类

按照作者使用习惯，简单提供了一个Helper类

using System.IO;
using System.Text;
using ProtoBuf;

namespace ConsoleApplication1
{
   public class ProtobufHelper
    {
       /// <summary>
       /// 序列化
       /// </summary>
       /// <typeparam name="T"></typeparam>
       /// <param name="t"></param>
       /// <returns></returns>
       public static string Serialize<T>(T t)
       {
           using (MemoryStream ms = new MemoryStream())
           {
               Serializer.Serialize<T>(ms, t);
               return Encoding.UTF8.GetString(ms.ToArray());
           }
       }

       /// <summary>
       /// 反序列化
       /// </summary>
       /// <typeparam name="T"></typeparam>
       /// <param name="content"></param>
       /// <returns></returns>
       public static T DeSerialize<T>(string content)
       {
           using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(content)))
           {
               T t = Serializer.Deserialize<T>(ms);
               return t;
           }
       }
    }
}

4：操作体验

代码很简单，就不分开贴了

using System;
using System.Collections.Generic;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            var p1 = new Person
            {
                Id = 1,
                Name = "八百里开外",
                Address = new Address
                {
                    Line1 = "Line1",
                    Line2 = "Line2"
                }
            };

            var p2 = new Person
            {
                Id = 2,
                Name = "一枪",
                Address = new Address
                {
                    Line1 = "Flat Line1",
                    Line2 = "Flat Line2"
                }
            };

            List<Person> pSource = new List<Person>() { p1, p2 };

            string content = ProtobufHelper.Serialize<List<Person>>(pSource);

            Console.Write(content);
            //写入文件
            File.WriteAllText("D://hello.txt", content);
             


            Console.WriteLine("\r\n****解析部分*****");

            List<Person> pResult = ProtobufHelper.DeSerialize<List<Person>>(content);


            foreach (Person p in pResult)
            {
                Console.WriteLine(p.Name);
            }

            Console.Read();
        }
    }
}
