What about this JSON? What's wrong with it?

i think your json should look like this
[{
"id": 13422,
"user_name": "HaMe",
"id_number": "888888887052",
"card_number": "297c2231",
"breakfasts": "1111100",
"lunchs": "1111100",
"dinners": "0000000",
"start_date": "01/10/2015 00:01",
"end_date": "25/05/2016 23:59",
"canteen": "Askhana 1",
"only_once": false
}, {
"id": 13516,
"user_name": "КаBa",
"id_number": "888888887400",
"card_number": "293ca641",
"breakfasts": "1111111",
"lunchs": "1111111",
"dinners": "1111111",
"start_date": "11/10/2015 00:01",
"end_date": "31/12/2015 23:59",
"canteen": "Askhana 1",
"only_once": true
}]

at the end of json the last brace will not be followed with comma and square bracket is also missing i doubt if you posted the full json here u just copy pasted half of it i guess or your json itself is wrong

Temirgali 7-Jan-16 3:07am

yes, you are right. my json like you typed, I just copied part, I guess it is understandable for developers. but, there problem isn't with json, problem with getting it. How can I map it into datatable. I don't have any idea.

yeleswarapu ramakrishna 7-Jan-16 4:44am

can you paste complete json here you need this in c# or on clientside(javascript)

gdeal_id: 14730,

jana: false
}
]
}
]

here is all completed JSON. I want it in c# i already did it but,i have problem with "gtransaction" part.

here a code:

public class MyObject
{

public int id { get; set; }
public string user_name { get; set; }
public string id_number { get; set; }
public string card_number { get; set; }
public string breakfasts { get; set; }
public string lunchs { get; set; }
public string dinners { get; set; }
public DateTime start_date { get; set; }
public DateTime end_date { get; set; }
public string only_once { get; set; }

}

download JSON

private static T downloadJsonData<t>(string url) where T : new() {
using (var w = new WebClient()) {
var jData = string.Empty;
try
{
jData = w.DownloadString(url);
}
catch (Exception) { }

return !string.IsNullOrEmpty(jData) ? JsonConvert.DeserializeObject<t>(jData) : new T();
}
}

private void button1_Click(object sender, EventArgs e)
{
var url = "http://185.98.5.184:9000/users/dealed/Test";
var obj = downloadJsonData<myobject>(url);

var db = new Models.Database1Entities();
db.Users.Add(new Models.Users
{
user_name = obj.user_name,
Id = obj.id,
id_number = obj.id_number,
card_number = obj.card_number,
card_number = obj.card_number,
breakfasts = obj.breakfasts,
lunchs = obj.lunchs,
dinners_ = obj.dinners,
only_once = obj.only_once,
start_date = obj.start_date,
end_date = obj.end_date

});
