c#处理3种json数据的实例

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。
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：

南方数据企业网站管理系统11 bulid 080901 全屏修正版

南方数据企业网站管理系统 V11.0全屏版新增功能:1.首页模板布局做了全新的调整;2.新增了企业网站广告管理系统,可以在后台随意增加和修改Banner广告、对联广告、浮动广告、弹出广告;3.新增了QQ在线资讯功能，同时还有N种模板选择;4.更换了网站统计管理系统；5.对菜单进行了加粗处理,显得更美观;6.后台使用了全新的静态编辑器,提高了后台打开编辑器的速度;7.新增了一个模板;8.修改了中英文

 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;
}
