c# json处理（转）

一、C#处理简单json数据

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

以jsonmy1.txt文件的形式保存在d盘json文件夹下。

构造对象：代码如下:

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：

代码如下:

public static void JsonMy()

{

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.Deserialize<ToJsonMy>(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 queryorder_info = list.res_info;

}

二、C#处理包含对象的json数据

json数据：jsonmy2.txt

代码如下:

{"result":"0",

"res_info":"ok",

"queryorder_info":{"order_num":"5","orderdetail":"ok"}

}

构造对象：代码如下:

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：代码如下:

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.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：jsonmy4.txt

代码如下:

{
"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": "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": "2013-10-1800:00:00",
"CityID": "0201",
"CurrencyCode": "RMB",
"HotelID": "10201314",
"HotelName": "凯顿",
"ListID": "1000000005201308280002999413",
"PayAmt": "1140",
"PayType": "0",
"RommsCnt": "1",
"SPTransID": "65197226",
"State": "4"
}
]
}
}

构造对象：

代码如下:

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：

代码如下:

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;

}
