一、C#处理简单json数据 json数据：

 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：

 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：

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

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

构造对象：

 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：

 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

 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：

 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：

 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;
}
