Newtonsoft.json中 linq to json 和序列化哪个快？

Newtonsoft.json是最常用的json序列化组件，当然他不是最快的，但是是功能最全的。。

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Diagnostics;

using Newtonsoft.Json.Linq;

using Newtonsoft.Json;

namespace ConsoleApplication2

{

public class Entity

{

public int a;

public bool b = false;

public string s = "asdfgb";

public double d = 123.456;

}

class Program

{

static void Main(string[] args)

{

Stopwatch w = new Stopwatch();

w.Start();

for (int i = 0; i <= 1000; i++)

{

Entity a = new Entity();

a.a = i;

string result = new JObject(new JProperty("a", i),

new JProperty("b", a.b),

new JProperty("s", a.s),

new JProperty("d", a.d)

).ToString();

}

w.Stop();

Console.WriteLine(w.ElapsedMilliseconds);

w.Reset();

w.Start();

for (int i = 0; i <= 1000; i++)

{

try

{

//Entity a = new Entity();

//a.a = i;

string result = JsonConvert.SerializeObject(new

{

a = i,

b = false,

s = "asdfgb",

d = 123.456

});

}

catch (Exception e)

{

}

}

w.Stop();

Console.WriteLine(w.ElapsedMilliseconds);

w.Reset();

w.Start();

for (int i = 0; i <= 1000; i++)

{

try

{

//Entity a = new Entity();

//a.a = i;

string result = string.Format("{a: {0},b:{1},s:{2}},d:{3}",

i, false, "asdfgb", 123.456);

}

catch (Exception e)

{

}

}

w.Stop();

Console.WriteLine(w.ElapsedMilliseconds);

Console.Read();

}

}

}

最终结果整理：

方式：　　linq　　序列化　　字符串

100：　　28　　104　　11

1000:　　32 　　108  　　41

10000:　　69　　126　　337

100000:　　425　　318 　　3341

随着次数的增加，估计反射的缓存还是很快的，序列化速度超过了linq to json,拼字符串从最快的变成最慢的
