准备工作：

1、添加引用System.Web.Extensions,

2、.net3.5+版本都有，如果VS2010找不到，在这个文件夹找：C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\

3、再using System.Web.Script.Serialization;即可

 

实现：

方法一

　　　　　　　var js = new System.Web.Script.Serialization.JavaScriptSerializer();            string json = "{\"offlineLock\":[{\"id\":\"4028d808581dab0f01581db51405001e\",\"mac\":\"D4:3D:7E:5F:B7:44\",\"sdsl\":5,\"sdrq\":1477967156304,\"shlb\":\"0\"}],\"flag\":\"success\",\"status\":\"1400\",\"resultList\":[{\"id\":\"4028d808581dab0f01581db5145c001f\",\"zwjyzsbh\":\"1000001600000052\",\"sfyfz\":\"0\"},{\"id\":\"4028d808581dab0f01581db514780020\",\"zwjyzsbh\":\"1000001600000054\",\"sfyfz\":\"0\"},{\"id\":\"4028d808581dab0f01581db514950021\",\"zwjyzsbh\":\"1000001600000056\",\"sfyfz\":\"0\"},{\"id\":\"4028d808581dab0f01581db514b20022\",\"zwjyzsbh\":\"1000001600000058\",\"sfyfz\":\"0\"},{\"id\":\"4028d808581dab0f01581db514cc0023\",\"zwjyzsbh\":\"1000001600000060\",\"sfyfz\":\"0\"}]}";            var jarr = js.Deserialize
     
      
       >(json);            foreach(var j in jarr)            {                Console.WriteLine(string.Format("{0}:{1}", j.Key, j.Value));            }            Console.ReadLine();
      
     

 

方法二：

1、建好实体类，对应json数据里的key

class Lock    {        public List
     
       offlineLock { get; set; }        public string flag { get; set; }        public string status { get; set; }        public List
      
        resultList { get; set; } }
      
     

class OfflineLock    {        public string id { get; set; }        public string mac { get; set; }        public long sdsl { get; set; }        public long sdrq { get; set; }        public string shlb { get; set; }    }

class ResultList

{ public string id { get; set; } public string sfyfz { get; set; } public string zwjyzsbh { get; set; } }

 

2、JavaScriptSerializer 解析Json数据

string json = "{\"offlineLock\":[{\"id\":\"4028d808581dab0f01581db51405001e\",\"mac\":\"D4:3D:7E:5F:B7:44\",\"sdsl\":5,\"sdrq\":1477967156304,\"shlb\":\"0\"}],\"flag\":\"success\",\"status\":\"1400\",\"resultList\":[{\"id\":\"4028d808581dab0f01581db5145c001f\",\"zwjyzsbh\":\"1000001600000052\",\"sfyfz\":\"0\"},{\"id\":\"4028d808581dab0f01581db514780020\",\"zwjyzsbh\":\"1000001600000054\",\"sfyfz\":\"0\"},{\"id\":\"4028d808581dab0f01581db514950021\",\"zwjyzsbh\":\"1000001600000056\",\"sfyfz\":\"0\"},{\"id\":\"4028d808581dab0f01581db514b20022\",\"zwjyzsbh\":\"1000001600000058\",\"sfyfz\":\"0\"},{\"id\":\"4028d808581dab0f01581db514cc0023\",\"zwjyzsbh\":\"1000001600000060\",\"sfyfz\":\"0\"}]}";            JavaScriptSerializer  js = new JavaScriptSerializer();            Lock str=js.Deserialize
     
      (json);            Console.WriteLine(str.offlineLock[0].id);//控制台输入试试            Console.ReadLine();
