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：

 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;
}
