Detailed explanation of serialization and deserialization using Protobuffer in .NET

Use Protobuffer to implement serialization and deserialization in .NET

1. Go to the official website to download protobuf-net.dll, Official address: http://code.google.com/p/protobuf-net/

2. Build a console application

3. Add class library: protobuf-net.dll to the application.

Sample code:

Prepare an entity class to be tested (note that the class and method must have the protoBuffer serialization feature):

[ProtoContract]
   public class Student
   {
       [ProtoMember(1)]
       public intStudentId { get; set; }
       [ProtoMember(2)]
       public stringName { get; set; }
       [ProtoMember(3)]
       public stringClassName { get; set; }
   }

Then test this class Serialization and Deserialization

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ProtoBuf;
using ProtoBufferDemo.Entity;
using System.IO;

namespace ProtoBufferDemo
{
   class Program
   {
        private const string TestPath = @"D:/1.txt";
        static void Main(string[] args)
        {
            ////////////////////////序列化//////////////////////////////

            Student stu = new Student()
            {
                StudentId = 1,
                Name = "zhangsan",
                ClassName = "classOne"
            };

            if (!File.Exists(TestPath))
            {
               FileStream fs = File.Create(TestPath,1024, FileOptions.Asynchronous);
               fs.Dispose();
            }

            Console.WriteLine("开始序列化并导出到文件...");
            using (Stream s = new FileStream(TestPath,FileMode.Open ,FileAccess.ReadWrite))
            {
                Serializer.Serialize<Student>(s, stu);
                s.Close();
            }
            Console.WriteLine("序列化完毕");

            //////////////////////反序列化////////////////////////////

            Console.WriteLine("反序列化并输出...");
            using (Stream s = new FileStream(TestPath,FileMode.Open))
            {
                Student st = Serializer.Deserialize<Student>(s);
                Console.WriteLine("studentName:"+ stu.Name + "/r/n" +
                                  "studentId:"+ stu.StudentId + "/r/n" +
                                  "className:" + stu.ClassName);
                s.Close();
            }

            Console.Read();
        }
   }
}

Now consider the situation of multiple entities and test itSerializing a collection:

class Program
   {
        private const string TestPath = @"D:/1.txt";
        static void Main(string[] args)
        {
            ////////////////////////序列化//////////////////////////////

            List<Student> stu = new List<Student>()
            {
                new Student(){
                StudentId = 1,
                Name = "zhangsan",
                ClassName = "classOne"},

                new Student(){StudentId = 2,
                Name = "lisi",
                ClassName = "classTwo"}
            };

            if (!File.Exists(TestPath))
            {
                FileStream fs = File.Create(TestPath,1024, FileOptions.Asynchronous);
                fs.Dispose();
            }

            Console.WriteLine("开始序列化并导出文件...");
            using (Stream s = new FileStream(TestPath,FileMode.Open, FileAccess.ReadWrite))
            {
                Serializer.Serialize<List<Student>>(s,stu);
                s.Close();
            }
            Console.WriteLine("序列化完毕");

            //////////////////////反序列化////////////////////////////

            Console.WriteLine("反序列化并输出...");
            using (Stream s = new FileStream(TestPath,FileMode.Open))
            {
                List<Student> sl = Serializer.Deserialize<List<Student>>(s);

                foreach (var student in sl)
                {
                    Console.WriteLine("studentName:"+ student.Name + "/r/n" +
                                "studentId:" + student.StudentId + "/r/n" +
                                "class Name:" + student.ClassName);
                }


                s.Close();
            }

            Console.Read();
        }
   }
