Protobuf-Net 下载安装使用

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

Nuget里搜索Protobuf-net，下载，自动添加到项目中

项目引用中添加你需要的protobuf-net版本（在文件夹中找到dll拖拽到引用中）

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

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

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();}}}
