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：
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;
}
