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; } } 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liststring 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#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liststring 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; }

在項目中也遇到了使用JSON的情況，就把轉化過程寫一下。

1.從數據庫獲取的json數據為：

[{"ACTIONVALUE":"-1","CONTENT":"","DEVID":"30000449636001","DEVNAME":"#1空調","DEVTYPE":"46","EVENTTYPE":"","GRIDCODE":"","ISAUTO":"false","MEASURENAME":"通用.低風","MEASURETAG":"GEN.CtrlLowWind","STREAMTYPE":null,"TIMESPAN":""},{"ACTIONVALUE":"0","CONTENT":"","DEVID":"30000449660712","DEVNAME":"#1風機","DEVTYPE":"56","EVENTTYPE":"","GRIDCODE":"","ISAUTO":"false","MEASURENAME":"風機開關","MEASURETAG":"GEN.UnibitCtrl","STREAMTYPE":null,"TIMESPAN":""},{"ACTIONVALUE":"1","CONTENT":"","DEVID":"30000449660710","DEVNAME":"#1警笛","DEVTYPE":"57","EVENTTYPE":"","GRIDCODE":"","ISAUTO":"false","MEASURENAME":"警笛開關","MEASURETAG":"GEN.UnibitCtrl","STREAMTYPE":null,"TIMESPAN":""},{"ACTIONVALUE":"1","CONTENT":"","DEVID":"30000449660708","DEVNAME":"#1燈光","DEVTYPE":"45","EVENTTYPE":"","GRIDCODE":"","ISAUTO":"true","MEASURENAME":"燈光開光","MEASURETAG":"GEN.UnibitCtrl","STREAMTYPE":null,"TIMESPAN":""},{"ACTIONVALUE":"66","CONTENT":"","DEVID":"30000449667767","DEVNAME":"hik1","DEVTYPE":"49","EVENTTYPE":"","GRIDCODE":"110100000103010001","ISAUTO":"true","MEASURENAME":"","MEASURETAG":"GEN.PreSet","STREAMTYPE":"150","TIMESPAN":""},{"ACTIONVALUE":"-1","CONTENT":"","DEVID":"30000449667767","DEVNAME":"hik1","DEVTYPE":"49","EVENTTYPE":"","GRIDCODE":"110100000103010001","ISAUTO":"true","MEASURENAME":"","MEASURETAG":"GEN.VideoRecord","STREAMTYPE":"150","TIMESPAN":""}]

2.構造實體對象：

public class ActionParam{//[{"ACTIONVALUE":"1","CONTENT":"","DEVID":"30000449660708","DEVNAME":"#1燈光","DEVTYPE":"45","EVENTTYPE":"","GRIDCODE":"","ISAUTO":"true","MEASURENAME":"燈光開光","MEASURETAG":"GEN.UnibitCtrl","STREAMTYPE":null,"TIMESPAN":""}]public int ACTIONVALUE { get; set; }public string CONTENT { get; set; }public string DEVID { get; set; }public string DEVNAME { get; set; }public string DEVTYPE { get; set; }public string EVENTTYPE { get; set; }public string GRIDCODE { get; set; }public bool ISAUTO { get; set; }public string MEASURENAME { get; set; }public string MEASURETAG { get; set; }public string STREAMTYPE { get; set; }public string TIMESPAN { get; set; }}

3.轉化為C#中聲明的數據格式：

JavaScriptSerializer js = new JavaScriptSerializer(); //實例化一個能夠序列化數據的類List<ActionParam> listDetail = js.Deserialize<List<ActionParam>>(actionParam);

以為json字符串是數組格式，所以js.Deserialize<T>()泛型中使用List<ActionParam>.
