{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.DeserializeToJsonMy(json); //将json数据转化为对象类型并赋值给liststring 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.DeserializeToJsonMy2(json); //将json数据转化为对象类型并赋值给liststring 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 Listorderdetail 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.DeserializeToJsonMy3(json); //将json数据转化为对象类型并赋值给liststring result list.result; string res_info list.res_info;string order_num list.queryorder_info.order_num;Listorderdetail 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;
