c# json数据解析——将字符串json格式数据转换成对象

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。

1.json简单对象

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:
c# json数据解析——将字符串json格式数据转换成对象
 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:

c# json数据解析——将字符串json格式数据转换成对象
 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; }

2.json还包含对象

json数据:jsonmy2.txt

{"result":"0","res_info":"ok","queryorder_info":{"order_num":"5","orderdetail":"ok"}}
构造对象:
c# json数据解析——将字符串json格式数据转换成对象
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; }
        };
c# json数据解析——将字符串json格式数据转换成对象

转换过程:

c# json数据解析——将字符串json格式数据转换成对象
  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;
        }

3.json包含对象数组 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:
c# json数据解析——将字符串json格式数据转换成对象
 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; } };

 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;
        }
