jons有微软自带的类库，也有官方的类库，都可以解析啊

在这里你写上json都可以查到微软自带的库

你的JsonConvert所属哪个命名空间啊我这里找不到
是不是引用Win8的第三方类库了

Newtonsoft.Json;
using Newtonsoft.Json.Linq
批这两个是官方的，你网上搜索去，
using System.Runtime.Serialization.Json 　
System.Runtime.Serialization.dll

我在网上下载了一个他告诉我是.netframework类库不是.netCore类库啊

用 nuget 啊install-package Newtonsoft.Jsonhttp://www.nuget.org/packages/Newtonsoft.Json

楼主可真懒，楼上都给出方案了，而且代码都给你贴出来了。还在埋怨？您不适合做程序员，还是当老板比较好。
我给你个下载地址，http://download-codeplex.sec.s-msft.com/Download/Release?ProjectName=json&DownloadId=668468&FileTime=130113389453430000&Build=20626

百度json工具，或者自己写解析工具，json的格式跟js的对象格式一模一样

谷歌一下好多的，newtonsoft.json或者用自带的解析

调试易
