上手protobuf
为什么要使用protobuf呢?
项目中有一个查询带导出excel模块,查询的时候是分页,但导出excel是不分页的.用.Net自身的二进制序列化比较慢,到数据量一个,会报内存溢出.1. protobuf-net下载
https://github.com/mgravell/protobuf-net2. 解压下载,编译时遇到的问题
生成时,错误提示
修改之前c#语言版本
将c#的版本修改为6.0
简单上手
using ProtoBuf;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
namespace ProtoBufApp
{
[ProtoContract]
class People
{
[ProtoMember(1)]
public int Id { get; set; }
[ProtoMember(2)]
public string Name { get; set; }
[ProtoMember(3)]
public int Age { get; set; }
}
class Program
{
static void Main(string[] args)
{
//计时
Stopwatch sw = new Stopwatch();
//这里只是模拟100万数据
List<People> list1 = new List<People>();
Random random = new Random();
People p1 = null;
for (int i = 0; i < 1000000; i++)
{
p1 = new People()
{
Id = i,
Name = "hello" + i,
Age = random.Next(1, 100)
};
list1.Add(p1);
}
sw.Start();
using (var stream = File.Create("people.bin"))
{
Serializer.Serialize(stream, list1); //进行序列化
}
sw.Stop();
Console.WriteLine($"->序列化耗时:{sw.ElapsedMilliseconds}ms");
sw.Restart();
List<People> list2 = null;
using (var stream = File.OpenRead("people.bin"))
{
list2 = Serializer.Deserialize<List<People>>(stream); //进行反序列化
}
sw.Stop();
Console.WriteLine($"->反序列化耗时:{sw.ElapsedMilliseconds}ms");
Console.ReadKey();
}
}
}效果(还是比自身二进制序列化快的)
后期慢慢集成到wcf的服务中去.
