[ASP.net教程]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.cnblogs.com/zhaofuchun/p/4434681.html 

一、C#处理简单json数据
json数据:

复制代码 代码如下:
{"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:

复制代码 代码如下:

 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:

复制代码 代码如下:
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

复制代码 代码如下:
{"result":"0","res_info":"ok","queryorder_info":{"order_num":"5","orderdetail":"ok"}}

 



构造对象:

复制代码 代码如下:
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:

复制代码 代码如下:
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

复制代码 代码如下:
{"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:

复制代码 代码如下:
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:

复制代码 代码如下:
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;}
