Asp.net C# Json 数据的读取方式

头部引入：

using System.Web.Script.Serialization;
using System.Collections.Generic;

string jsonStr = "{\"error\":0,\"msg\":\"ok\"}";

        JavaScriptSerializer serializer = new JavaScriptSerializer();
        Dictionary<string, object> json = (Dictionary<string, object>)serializer.DeserializeObject(jsonStr);

        object value;

        if (json.TryGetValue("msg", out value))

            Response.Write(value);

如果是在类库中需要添加引用：

System.Web.Extensions
