c#處理3種json數據的方式

原文出處：http://www.jb51.net/article/48027.htm

一、C#處理簡單json數據

json數據：

{"result":"0","res_info":"ok","queryorder_info":"info"}

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 jsonstr = @{“"result"”:“”0“”,“"res_info"”:“"ok"”,“"queryorder_info"”:“"info"”}  ;         　　　　　　 

    JavaScriptSerializer js = new JavaScriptSerializer();   //實例化一個能夠序列化數據的類
    ToJsonMy list = js.Deserialize<ToJsonMy>(jsonstr);    //將json數據轉化為對象類型並賦值給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：

{"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 jsonstr =@ {""result"":""0"",""res_info"":""ok"",""queryorder_info"":{""order_num"":""5"",""orderdetail"":""ok""}};
    ToJsonMy2 list = js.Deserialize<ToJsonMy2>(json);    //將json數據轉化為對象類型並賦值給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：

{"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並賦值給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;
}
