JsonConvert.DeserializeObject not working in .net

I am not getting JsonConvert.DeserializeObject to work for me.
I get the correct value in JSON from the service. Not finding anything online for this, would appreciate a little help here :)
Here is my code:
public partial class _Default : Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void tbPlate_OnServerChange(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(tbPlate.Text))
{
var _res = Responses(tbPlate.Text);
if (_res.Vehicles != null)
{
lblTestText.Text = _res.Vehicles.FirstOrDefault(r => r.regNr == tbPlate.Text)?.ToString();
}
else
{
lblTestText.Text = "No vehicle data";
}
}
}
private static VehicleResults Responses(string regNr)
{
var _jSon = "";
var _url = #"http://apis.is/car";
var _res = new VehicleResults();
var _request = (HttpWebRequest)WebRequest.Create($"{_url}?number={regNr}");
var _response = _request.GetResponse();
using (var _responseStream = _response.GetResponseStream())
{
var _reader = new StreamReader(_responseStream, Encoding.UTF8);
_jSon = _reader.ReadToEnd();
}
_res = JsonConvert.DeserializeObject<VehicleResults>(_jSon);
return _res;
}
}
public class VehicleResponse
{
[JsonProperty("registryNumber")]
public string regNr { get; set; }
public string number { get; set; }
public string factoryNumber { get; set; }
public string type { get; set; }
public string subType { get; set; }
public string color { get; set; }
public string registeredAt { get; set; }
public string status { get; set; }
public string nextCheck { get; set; }
public string pollution { get; set; }
public string weight { get; set; }
}
public class VehicleResults
{
public List<VehicleResponse> Vehicles { get; set; }
}
This is the response JSON from the service:
{"results":[{"type":"MERCEDES BENZ - M (Svartur)","subType":"M","color":"Svartur","registryNumber":"GXS56","number":"GXS56","factoryNumber":"WDC1631131A539035","registeredAt":"23.09.2004","pollution":" g/km","weight":"2200 kg","status":"Í lagi","nextCheck":"01.06.2019"}]}
I am quite new to REST services so I believe that the problem is small....I am just not able to figure it out right now.

Your json has a root object that contains the list of your vehicles.
You need to name the variable that holds your list with the name returned in the json. results
public class VehicleResults
{
// This should be named results
public List<VehicleResponse> results {get;set;}
}
Now you can deserialize with
VehicleResults data = JsonConvert.DeserializeObject<VehicleResults>(json);
foreach(var vei in data.results)
Console.WriteLine(vei.type);

You need to [JsonProperty] on every property in VehicleResponse
Please add _reader.Close() at the end of the using

How to do json data list<T> show dataGridView

I'm using the Newtonsoft library for parsing JSON:
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
I have my json string and "MyClass" class.
JSON string:
{
"Result":
{
"MyClassList": [
{"Id":1,"Amount":"5,00"},
{"Id":2,"Amount":"10,00"},
{"Id":3,"Amount":"20,00"},
{"Id":4,"Amount":"25,00"}
]
"ReturnValues":
{
"ErrorCode":1,
"ErrorDescription":"Successful"
}
}
}
My Class:
public class MyClass
{
[JsonProperty("Id")]
Int64 Id { get; set; }
[JsonProperty("Amount ")]
string Amount { get; set; }
}
I am getting json data using these classes "GetMyClassList", "RootObject" and "ReturnValues".
List<MyClass> GetMyClassList()
{
JObject jo = new JObject();
List<MyClass> myClassList = new List<MyClass>();
jo.Add("Name", "Name");
jo.Add("Surname", "Surname");
url = "MyUrl";
string responseText = ExecuteHttpRequest(url , "POST",
"application/json", Encoding.UTF8.GetBytes(jo.ToString()), 3000);
myClassList = JsonConvert.DeserializeObject<RootObject>(responseText)
.GetMyClassListResult.MyClassList;
return myClassList;
}
public class ReturnValues
{
public int ErrorCode { get; set; }
public string ErrorDescription { get; set; }
}
public class GetMyClassListResult
{
[JsonProperty("MyClassList")]
public List<MyClass> MyClassList { get; set; }
public ReturnValues ReturnValues { get; set; }
}
public class RootObject
{
public GetMyClassListResult GetMyClassListResult { get; set; }
}
I cannot get this data array (Id and amount).
and I want to take this data and show it in a dataGridView.

The best way to t-shoot this is set breakpoint at the line, where u getting the results from method -> is it filled? This Line:
return myClassList;
I have run Your code with single adjustment -> I have just used the direct JSON (not from web) - code below. This run without issues and I can see all the results parsed out of the JSON.
You have to find if the issue is parsin the JSON, or setting the data to the DataGridTable (which code You have not included at all).
class Program
{
static void Main(string[] args)
{
var result = new Program().GetMyClassList();
foreach (var item in result)
Console.WriteLine($"ID: {item.Id}\tAmount:{item.Amount}");
Console.ReadKey();
}
public List<MyClass> GetMyClassList()
{
List<MyClass> myClassList = new List<MyClass>();
string responseText = "{\"GetMyClassListResult\":{\"MyClassList\":[{\"Id\":1,\"Amount\":\"5,00\"},{\"Id\":2,\"Amount\":\"10,00\"},{\"Id\":3,\"Amount\":\"20,00\"},{\"Id\":4,\"Amount\":\"25,00\"}],\"ReturnValues\":{\"ErrorCode\":1,\"ErrorDescription\":\"Successful\"}}}";
myClassList = JsonConvert.DeserializeObject<RootObject>(responseText)
.GetMyClassListResult.MyClassList;
return myClassList;
}
}
public class MyClass
{
[JsonProperty("Id")]
public Int64 Id { get; set; }
[JsonProperty("Amount")]
public string Amount { get; set; }
}
public class ReturnValues
{
public int ErrorCode { get; set; }
public string ErrorDescription { get; set; }
}
public class GetMyClassListResult
{
[JsonProperty("MyClassList")]
public List<MyClass> MyClassList { get; set; }
public ReturnValues ReturnValues { get; set; }
}
public class RootObject
{
public GetMyClassListResult GetMyClassListResult { get; set; }
}

all values not coming while parsing json to string in c#

i have j son data in string in j son response. I'm able to get only request-id value. other are coming in debugging but unable to retrieve from dictionary type.can u tell me how to get other values of a mobile number- date , status and description.
screen shot added kindly go through it http://postimg.org/image/6iad15yxl/
my j son data
{
"requestId": "546b384ce51f469a2e8b4567",
"numbers": {
"917566551111": {
"date": "2014-11-18 17:45:59",
"status": 1,
"desc": "DELIVERED"
}
}
}
C# code
public partial class jsontoCsharp : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
json = Request.QueryString["data"];
var req = JsonConvert.DeserializeObject<Request>(json);
string requestid = req.requestId;
}
}
public class smsstatus
{
public string date { get; set; }
public int status { get; set; }
public string desc { get; set; }
}
public class Request
{
public string requestId { get; set; }
public Dictionary<string, smsstatus> numbers { get; set; } //<-- See this line
}

Your model should be something like this
public class smsstatus
{
public string date { get; set; }
public int status { get; set; }
public string desc { get; set; }
}
public class Request
{
public string requestId { get; set; }
public Dictionary<string, smsstatus> numbers { get; set; } //<-- See this line
}
Now these deserializations will work
var req = JsonConvert.DeserializeObject<Request>(json);
or
var req = new JavaScriptSerializer().Deserialize<Request>(json);

As your Json is quite complex, try as following..
var results = JsonConvert.DeserializeObject<dynamic>(json);
var result is containing your deserialized json now you can access the results object using dot (.) notation

using JSON response from REST api with nonstandard names

{"balances-and-info":{"on_hold":[],"available": {"USD":0.93033384},"usd_volume":"243.18","fee_bracket": {"maker":"0.00","taker":"0.60"},"global_usd_volume":"0.09942900"}}
I have this JSON response, and I'm trying to store it in an object, however as you can see "balances-and-info" cannot be used as a variable name. The method I have been using is:
RestClient client = new RestClient("http://currency-api.appspot.com/api/");
RestRequest request = new RestRequest(url);
var response = client.Execute<Currency>(request);
Currency obj = response.Data;
Where obviously the class is a lot easier
public class Currency
{
public string rate { get; set; }
}
So how can I handle this?

String.replace() balances-and-info with balances_and_info
in your code
YourObject deserialized = parseResponse(obj.replace("balances-and-info", "balances_and_info"));
YourObject parseResponse(string response) {
try
{
// https://www.nuget.org/packages/Newtonsoft.Json/
// Json.NET
YourObject ret = JsonConvert.DeserializeObject<YourObject>(response);
return ret;
}
catch (JsonSerializationException)
{
// do something
}
return null;
}
YourObject
Use http://json2csharp.com/ and generate your object (copy response string, replace balances-and-info with balances_and_info and generate)
public class Available
{
public double USD { get; set; }
}
public class FeeBracket
{
public string maker { get; set; }
public string taker { get; set; }
}
public class BalancesAndInfo
{
public List<object> on_hold { get; set; }
public Available available { get; set; }
public string usd_volume { get; set; }
public FeeBracket fee_bracket { get; set; }
public string global_usd_volume { get; set; }
}
public class YourObject
{
public BalancesAndInfo balances_and_info { get; set; }
}

Serialize deserialize anonymous child JSON properties to model

I have an API I am receiving data from. That API is out of my control on how it is structured, and I need to serialize and deserialize the JSON output to map the data to my model.
Everything works well where JSON is nicely formatted with named properties.
What can you do where there is no named value and there is just an array of ints and strings? like under locations
here is a sample of the JSON:
{"id":"2160336","activation_date":"2013-08-01","expiration_date":"2013-08-29","title":"Practice Manager","locations":{"103":"Cambridge","107":"London"}}
I have models that are like:
public class ItemResults
{
public int Id { get; set; }
public DateTime Activation_Date { get; set; }
public DateTime Expiration_Date{ get; set; }
public string Title { get; set; }
public Location Locations { get; set; }
}
public class Location
{
public int Id { get; set; }
public string value { get; set; }
}
and I am mapping using the inbuilt ajax serialization:
protected T MapRawApiResponseTo<T>( string response )
{
if ( string.IsNullOrEmpty( response ) )
{
return default( T );
}
var serialize = new JavaScriptSerializer();
return serialize.Deserialize<T>( response );
}
var results = MapRawApiResponseTo<ItemResults>(rawApiResponse);
So the ID and all other properties are picked up and mapped but what every I do I can not seem to map the locations.
Many thanks

public Dictionary<int,string> Locations { get; set; }
job done; you should find that using Json.NET, at least, i.e.
var result = JsonConvert.DeserializeObject<ItemResults>(json);
you get 2 entries in result.Locations; specifically result[103] = "Cambridge"; and result[107] = "London";

If you don't mind, you can workaround with dictionary:
class Program
{
static void Main(string[] args)
{
string json =
"{'id':'2160336','activation_date':'2013-08-01','expiration_date':'2013-08-29','title':'Practice Manager','locations':{'103':'Cambridge','107':'London'}}";
var deserializeObject = JsonConvert.DeserializeObject<ItemResults>(json);
Console.WriteLine("{0}:{1}", deserializeObject.Locations.First().Key, deserializeObject.Locations.First().Value);
Console.ReadKey();
}
}
public class ItemResults
{
public int Id { get; set; }
public DateTime Activation_Date { get; set; }
public DateTime Expiration_Date { get; set; }
public string Title { get; set; }
public Dictionary<int, string> Locations { get; set; }
}
you can also use manual parsing, like here: Json.NET (Newtonsoft.Json) - Two 'properties' with same name?

This will work:
public Dictionary<string, string> Locations { get; set; }
public IEnumerable<Location> LocationObjects { get { return Locations
.Select(x => new Location { Id = int.Parse(x.Key), value = x.Value }); } }

I propose you the following solution :
public class ItemResults
{
public int Id { get; set; }
public DateTime Activation_Date { get; set; }
public DateTime Expiration_Date { get; set; }
public string Title { get; set; }
[JsonProperty("locations")]
public JObject JsonLocations { get; set; }
[JsonIgnore]
public List<Location> Locations { get; set; }
[OnDeserialized]
public void OnDeserializedMethod(StreamingContext context)
{
this.Locations = new List<Location>();
foreach (KeyValuePair<string, JToken> item in this.JsonLocations)
{
this.Locations.Add(new Location() { Id = int.Parse(item.Key), value = item.Value.ToString() });
}
}
}
public class Location
{
public int Id { get; set; }
public string value { get; set; }
}
After you just have to deserialize your JSON with : JsonConvert.DeserializeObject<ItemResults>(json);
