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
