C# JsonString转Object以及Object转JsonString

主要讲述了两种方法的转换，最后提供了格式化输出JsonString字符串。

需要引用程序集 System.Web.Extensions.dll、Newtonsoft.Json.dll

System.Web.Extensions.dll可直接在程序集中引用，Newtonsoft.Json.dll需要在NuGet中下载引用。

详细代码：

using System;
using System.IO;
using Newtonsoft.Json;
using System.Collections.Generic;
using System.Web.Script.Serialization;
