网络中数据传输经常是xml或者json，现在做的一个项目之前调其他系统接口都是返回的xml格式，刚刚遇到一个返回json格式数据的接口，通过例子由易到难总结一下处理过程，希望能帮到和我一样开始不会的朋友。

1.json简单对象

json数据：

{"result":"0","res_info":"ok","queryorder_info":"info"}

我这里是以jsonmy1.txt文件的形式保存在d盘json文件夹下。

构造对象：

public struct ToJsonMy

{

       public string result { get; set; }  //属性的名字，必须与json格式字符串中的"key"值一样。

       public string res_info { get; set; }

       public string queryorder_info { get; set; }   }

转换过程：

public static void JsonMy()

       {

           string json = Jsonstr("D:\json\jsonmy1.txt");//Jsonstr函数读取json数据的文本txt                      

           JavaScriptSerializer js = new JavaScriptSerializer();   //实例化一个能够序列化数据的类

           ToJsonMy list = js.Deserialize<ToJsonMy>(json);    //将json数据转化为对象类型并赋值给list

           string result = list.result;                  

           string res_info = list.res_info;

           string queryorder_info = list.res_info;

       }

2.json还包含对象

json数据：jsonmy2.txt

{"result":"0","res_info":"ok","queryorder_info":{"order_num":"5","orderdetail":"ok"}}

构造对象：

public struct ToJsonMy2

       {

           public string result { get; set; }  

           public string res_info { get; set; }

           public queryorder_info queryorder_info;

       }

public struct queryorder_info

       {

           public string order_num { get; set; }

           public string orderdetail { get; set; }

       };

转换过程：

 public static void JsonMy2()

       {

           string json = Jsonstr("D:\json\jsonmy2.txt");

           JavaScriptSerializer js = new JavaScriptSerializer();   //实例化一个能够序列化数据的类

           ToJsonMy2 list = js.Deserialize<ToJsonMy2>(json);    //将json数据转化为对象类型并赋值给list

           string result = list.result;    

           string res_info = list.res_info;

           string order_num = list.queryorder_info.order_num;

           string orderdetail = list.queryorder_info.orderdetail;

       }

3.json包含对象数组 json数据：jsonmy4.txt

{"result":"0","res_info":"ok","queryorder_info":{"order_num":"5","orderdetail":[{"CFTUin":"769839263","CancelDeadline":"2013-09-12 23:00:00","CheckInDate":"2013-09-12 00:00:00","CheckOutDate":"2013-09-13 00:00:00","CityID":"0101","CurrencyCode":"RMB","HotelID":"00301105","HotelName":"乐家连锁（北京天坛南门店）（原速8酒店（北京天坛南门店）","ListID":"1000000005201308280002999652","PayAmt":"228","PayType":"0","RommsCnt":"1","SPTransID":"65202157","State":"4"},{"CFTUin":"248486133","CancelDeadline":"2013-10-13 23:00:00","CheckInDate":"2013-10-13 00:00:00","CheckOutDate":"2013-10-18 00:00:00","CityID":"0201","CurrencyCode":"RMB","HotelID":"10201314","HotelName":"上海凯顿酒店","ListID":"1000000005201308280002999413","PayAmt":"1140","PayType":"0","RommsCnt":"1","SPTransID":"65197226","State":"4"}]}}

构造对象：

public struct ToJsonMy3

       {

           public string result { get; set; }

           public string res_info { get; set; }

           public queryorder_info queryorder_info;

       }

 public struct queryorder_info

       {

           public string order_num { get; set; }

           public List<orderdetail> orderdetail;//数组处理      

};

public struct orderdetail

       {

           public string CFTUin { get; set; }

           public string CancelDeadline { get; set; }

           public string CheckInDate { get; set; }

           public string CheckOutDate { get; set; }

           public string CityID { get; set; }

           public string CurrencyCode { get; set; }

           public string HotelID { get; set; }

           public string HotelName { get; set; }

           public string ListID { get; set; }

           public string PayAmt { get; set; }

           public string PayType { get; set; }

           public string RommsCnt { get; set; }

           public string SPTransID { get; set; }

           public string State { get; set; }

       };

转换过程：

public static void JsonMy4()

       {

           string json = Jsonstr("D:\json\jsonmy4.txt");

           JavaScriptSerializer js = new JavaScriptSerializer();   //实例化一个能够序列化数据的类

           ToJsonMy3 list = js.Deserialize<ToJsonMy3>(json);    //将json数据转化为对象类型并赋值给list

           string result = list.result;    

           string res_info = list.res_info;

           string order_num = list.queryorder_info.order_num;

           List<orderdetail> orderdetail = list.queryorder_info.orderdetail;

           string CFTUin = orderdetail[0].CFTUin;

           string HotelName = orderdetail[0].HotelName;

           string ListID = orderdetail[1].ListID;

           string State = orderdetail[2].State;

       }
