網絡中數據傳輸經常是xml或者json，現在做的一個項目之前調其他系統接口都是返回的xml格式，剛剛遇到一個返回json格式數據的接口，通過例子由易到難總結一下處理過程，希望能幫到和我一樣開始不會的朋友。
一、C#處理簡單json數據
json數據：
{"result":"0","res_info":"ok","queryorder_info":"info"}
我這里是以jsonmy1.txt文件的形式保存在d盤json文件夾下。
構造對象：
public struct ToJsonMy
{
public string result { get; set; } //屬性的名字，必須與json格式字符串中的"key"值一樣。
public string res_info { get; set; }
public string queryorder_info { get; set; }
}
轉換過程：
public static void JsonMy()
{
string json = Jsonstr("D://json//jsonmy1.txt");//Jsonstr函數讀取json數據的文本txt
JavaScriptSerializer js = new JavaScriptSerializer(); //實例化一個能夠序列化數據的類
ToJsonMy list = js.Deserialize<ToJsonMy>(json); //將json數據轉化為對象類型并賦值給list
string result = list.result;
string res_info = list.res_info;
string queryorder_info = list.res_info;
}
二、C#處理包含對象的json數據
json數據：jsonmy2.txt
{"result":"0","res_info":"ok","queryorder_info":{"order_num":"5","orderdetail":"ok"}}
構造對象：
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; }
};
轉換過程：
public static void JsonMy2()
{
string json = Jsonstr("D://json//jsonmy2.txt");
JavaScriptSerializer js = new JavaScriptSerializer(); //實例化一個能夠序列化數據的類
ToJsonMy2 list = js.Deserialize<ToJsonMy2>(json); //將json數據轉化為對象類型并賦值給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#處理包含對象、數組的json數據
json數據：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":"樂家連鎖（北京天壇南門店）（原速8酒店（北京天壇南門店）","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":"上海凱頓酒店","ListID":"1000000005201308280002999413","PayAmt":"1140","PayType":"0","RommsCnt":"1","SPTransID":"65197226","State":"4"}]}}
構造對象：
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;//數組處理
};
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; }
};
轉換過程：
public static void JsonMy4()
{
string json = Jsonstr("D://json//jsonmy4.txt");
JavaScriptSerializer js = new JavaScriptSerializer(); //實例化一個能夠序列化數據的類
ToJsonMy3 list = js.Deserialize<ToJsonMy3>(json); //將json數據轉化為對象類型并賦值給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;
}
