c#处理3种json数据的方式

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

一、C#处理简单json数据

json数据：

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

构造对象：

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

    JavaScriptSerializer js = new JavaScriptSerializer();   //实例化一个能够序列化数据的类
    ToJsonMy list = js.Deserialize<ToJsonMy>(jsonstr);    //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

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 jsonstr =@ {""result"":""0"",""res_info"":""ok"",""queryorder_info"":{""order_num"":""5"",""orderdetail"":""ok""}};
    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

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;
}
