{[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 nameT/typeparam/// param namet/param/// returns/returnspublic static string SerializeT(T t){using (MemoryStream ms new MemoryStream()){Serializer.SerializeT(ms, t);return Encoding.UTF8.GetString(ms.ToArray());}}/// summary/// 反序列化/// /summary/// typeparam nameT/typeparam/// param namecontent/param/// returns/returnspublic static T DeSerializeT(string content){using (MemoryStream ms new MemoryStream(Encoding.UTF8.GetBytes(content))){T t Serializer.DeserializeT(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}};ListPerson pSource new ListPerson() { p1, p2 };string content ProtobufHelper.SerializeListPerson(pSource);Console.Write(content);//写入文件File.WriteAllText(D://hello.txt, content);Console.WriteLine(\r\n****解析部分*****);ListPerson pResult ProtobufHelper.DeSerializeListPerson(content);foreach (Person p in pResult){Console.WriteLine(p.Name);}Console.Read();}}
} 控制台运行结果 同样的数据和Json所占用空间对比高下立判 后记 protobuf虽然有千般好但是我们是在 web api上使用的前台js解析不了Protobuf所以只能用Json咯~ StackService虽然Github上有2K多个Star,但是收费的。。同样的事情web api 2也能做到所以也略过它。 最终作者选择了跑分测试里面的第二名Jil https://github.com/kevin-montrose/Jil 1. With very minimal annotation on the class level [ProtoContract(ImplicitFields ImplicitFields.AllPublic)] // only required on the class level
class PersonEntity
{public string FirstName { get; set; }public string LastName { get; set; }
} 2. Without any annotation (using RuntimeTypeModel) static void InitializeProtobufRunTime()
{var assembly Assembly.GetAssembly(typeof(PlainEntities.PersonEntity));var types assembly.GetTypes();foreach (var t in types.Where(x x.Namespace.Contains(PlainEntities))){Console.WriteLine(Processing {0}, t.FullName);var meta RuntimeTypeModel.Default.Add(t, false);var index 1;// find any derived class for the entityforeach (var d in types.Where(x x.IsSubclassOf(t))){var i index;Console.WriteLine(\tSubtype: {0} - #{1}, d.Name, i);meta.AddSubType(i, d);}// then add the propertiesforeach (var p in t.GetProperties(BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly).Where(x x.GetSetMethod() ! null)){var i index;Console.WriteLine(\tProperty: {0} - #{1}, p.Name, i);meta.AddField(i, p.Name);}}
} And both the above works quite well without any performance differences. ------------------TestBinaryEntities------------------Process: 100000 items, MemorySize: 7400705, Completed in: 3877 ms, Serialization took: 676 ms, Deserialization took: 2948 ms ----------------------------------TestProtobufFullyAnnotatedEntities----------------------------------Process: 100000 items, MemorySize: 3983490, Completed in: 682 ms, Serialization took: 164 ms, Deserialization took: 253 ms -------------------------------------TestProtobufImplicitAnnotatedEntities-------------------------------------Process: 100000 items, MemorySize: 3983490, Completed in: 595 ms, Serialization took: 104 ms, Deserialization took: 210 ms -------------------------------TestProtobufRuntimeRegistration-------------------------------Processing ProtobufTestConsole.PlainEntities.BaseEntitySubtype: PersonEntity - #1Property: Id - #2Property: Gender - #3Processing ProtobufTestConsole.PlainEntities.PersonEntityProperty: FirstName - #1Property: LastName - #2Property: Age - #3Process: 100000 items, MemorySize: 4083490, Completed in: 646 ms, Serialization took: 113 ms, Deserialization took: 232 ms Looking forward to get this in :) Also attached the sample project for reference 转载于:https://www.cnblogs.com/zhahost/p/5813627.html
