C#处理3种json数据的实例

原文地址：http://www.jb51.net/article/48027.htm

本篇采用 C#解析JSON方法（内置方法）http://www.VEVb.com/zhaofuchun/p/4434681.html

一、C#处理简单json数据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;}

二、C#处理包含对象的json数据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;}

三、C#处理包含对象、数组的json数据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;}
