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。 {"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。 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 {"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 {"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; }
