Getting a JsonSerializationException when trying to deserialize PlayerStats

I want to insert into my class data from JSON but I got a Newtonsoft.Json.JsonSerializationException.
My PlayerStats class is good, I think, and I don't know why it's not working.
I can download and print JSON to the console but my code stops working at the point when I try to deserialize. I tried to add settings to deserialize but it's still not working.
Here is my code:
using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;
using System;
using System.Net;
namespace DiscordBot
{
class Osu

public string _nickname;
private string _key = "key";

[JsonProperty("country")]

}
public PlayerStats GetUserStats()
{
string json = string.Empty;
var result = JsonConvert.DeserializeObject<PlayerStats>(json);
try
{
string url = #"https://osu.ppy.sh/api/get_user";
using (WebClient wc = new WebClient())
{
wc.QueryString.Add("k", _key);
wc.QueryString.Add("u", _nickname);
wc.QueryString.Add("m", "0");
json = wc.DownloadString(url);
Console.WriteLine(json);
result = JsonConvert.DeserializeObject<PlayerStats>(json);
return result;
}
}
catch (WebException ex)
{
Console.WriteLine("Osu Error: " + ex.Status);
}
return result;
}
}
}

Refer this Tested Answer from the file I have loaded your json and DeserializeObject check my model also and how I am DeserializeObject
namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
string data = File.ReadAllText("D://readjson.txt");
var obj = JsonConvert.DeserializeObject<List<RootObject>>(data);
}
}
public class RootObject
{
public string user_id { get; set; }
public string username { get; set; }
public string count300 { get; set; }
public string count100 { get; set; }
public string count50 { get; set; }
public string playcount { get; set; }
public string ranked_score { get; set; }
public string total_score { get; set; }
public string pp_rank { get; set; }
public string level { get; set; }
public string pp_raw { get; set; }
public string accuracy { get; set; }
public string count_rank_ss { get; set; }
public string count_rank_ssh { get; set; }
public string count_rank_s { get; set; }
public string count_rank_sh { get; set; }
public string count_rank_a { get; set; }
public string country { get; set; }
public string pp_country_rank { get; set; }
[JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
public List<object> events { get; set; }
}
}

Pp_country_rank and count_rank_s contains a space. This is trying to be parsed to an integer.
"count_rank_s":"3 6"
,"count_rank_sh":"13"
,"count_rank_a":"65"
,"country":"PL"
,"pp_country_rank":"77 20"

Retrieve Value From Nested Json

I have a Json as below.
{
"currency": "MYR",
"results": [
{
"itineraries": [
{
"outbound": {
"flights": [
{
"departs_at": "2018-06-03T06:25",
"arrives_at": "2018-06-03T07:25",
"origin": {
"airport": "PEN"
},
"destination": {
"airport": "KUL",
"terminal": "M"
},
"marketing_airline": "OD",
"operating_airline": "OD",
"flight_number": "2105",
"aircraft": "738",
"booking_info": {
"travel_class": "ECONOMY",
"booking_code": "Q",
"seats_remaining": 9
}
}
]
},
"inbound": {
"flights": [
{
"departs_at": "2018-06-04T14:10",
"arrives_at": "2018-06-04T15:10",
"origin": {
"airport": "KUL",
"terminal": "M"
},
"destination": {
"airport": "PEN"
},
"marketing_airline": "OD",
"operating_airline": "OD",
"flight_number": "2108",
"aircraft": "739",
"booking_info": {
"travel_class": "ECONOMY",
"booking_code": "O",
"seats_remaining": 5
}
}
]
}
}
],
"fare": {
"total_price": "360.00",
"price_per_adult": {
"total_fare": "360.00",
"tax": "104.00"
},
"restrictions": {
"refundable": false,
"change_penalties": true
}
}
}
]
}
And I use the code below to retrieve the value from the Json. I able to retrieve the "departs_at", "arrives_at", "marketing_airline" but I unable to retrieve the value inside "booking_info".
IOperations _obj = ClsOperations.GetOperations();
string url = "https://api.sandbox.amadeus.com/v1.2/flights/low-fare-search?apikey=" + APIKEY
+ "&origin=" + origin + "&destination=" + destination
+ "&departure_date=" + departureDate + "&return_date=" + returnDate
+ "&currency=" + currency + "&number_of_results=1";
string json = _obj.GetJsonResult(url);
JToken jToken = JToken.Parse(json);
JArray outBoundFlights = (JArray)jToken.SelectToken("results[0].itineraries[0].outbound.flights");
foreach (JToken obf in outBoundFlights)
{
TravelPlan.Text += "Departs At: " + obf["departs_at"] + "<br/>";
TravelPlan.Text += "Arrives At: " + obf["arrives_at"] + "<br/>";
TravelPlan.Text += "Airline: " + obf["marketing_airline"] + "<br/>";
}
JArray outBoundFlightsBooking = (JArray)jToken.SelectToken("results[0].itineraries[0].outbound.flights.booking_info");
foreach (JToken obfb in outBoundFlightsBooking)
{
TravelPlan.Text += "<br/>";
TravelPlan.Text += "Travel Class: " + obfb["travel_class"] + "<br/>";
TravelPlan.Text += "Seats Remaining: " + obfb["seats_remaining"] + "<br/>";
}
I wish to ask how possible I can retrieve the value inside the booking_info?
Thanks for every members here that help.

RootObject travelInfo = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json);
For Retrieving all bookingInfo in the json response.
foreach(Result result in travelInfo.results)
{
foreach(Itinerary itn in travelInfo.results[0].itineraries)
{
//For Inbound Flights
foreach (Flight2 fl2 in itn.inbound.flights)
{
Console.WriteLine("BookingCode:"+fl2.booking_info.booking_code);
Console.WriteLine("Seats Remaining:" + fl2.booking_info.seats_remaining);
Console.WriteLine("Travel Class:" + fl2.booking_info.travel_class);
}
//For Outbound Flights
foreach(Flight fl1 in itn.outbound.flights)

Console.WriteLine("Seats Remaining:" + fl1.booking_info.seats_remaining);
Console.WriteLine("Travel Class:" + fl1.booking_info.travel_class);
}
}
}
Output:
BookingCode:O
Seats Remaining:5
Travel Class:ECONOMY
BookingCode:Q
Seats Remaining:9
Travel Class:ECONOMY

Loop appropriately, i used index zero for a test case

I have another class containing public variables which I assign values to from code, and a method/function to instantiate my JSON class and pull in the values from the public variables.
I am getting a null reference exception on the line:

You'll need to initialize all objects (including child entities) before you can use them*, as they will otherwise adopt their default values (which will be null for objects). i.e. replace
NewShipmentObject.consignment.consignmentNumber = null;
with:
NewShipmentObject.consignment = new IS_Consignment();
NewShipmentObject.consignment.consignmentNumber = null;
You can save yourself a lot of typing - instead of line-by-line setting of each field, you can do so using Object Initializer Syntax:
var NewShipmentObject = new DPD_JSON.IS
{
job_id = null,
collectionOnDelivery = false,
consignment = new IS_Consignment
{
consignmentNumber = null,
... more consignment settings here
}
... etc.
It should be noted that you don't need to explicitly set uninitialized variables to their default value, i.e. both
job_id = null,
collectionOnDelivery = false
are redundant, as these should be the default values in any event.
* (unless this initialization is done automatically in the constructor)

Trouble with List (UWP)

Where is my problem.
As you see I have this public List<LineItem> line_items { get; set; } in classes. I need to take this list from RootObject and make Binding for values in it like I do for rootObject.
So what is logic of View in app. I Binв some data to Left panel, when I tap element on left panel, I make visible right panel, where I bind properties from public RootObject OrdersChange.
Here is some screens:
How I can do this?

If I understand correctly, you want bind 2 classes to one view. If so, I can suggest 2 ways:
1) Create base class for this 2 classes.
class BaseClass { }
class RootObject: BaseClass { }
class LineItem : BaseClass { }
class MainViewModel
{
public List<LineItem> ProductList { get; set; }
public List<RootObject> OrdersList { get; set; }
public BaseClass LeftListViewSelectedItem { get; set; }
}
2) Or you can set return type of property LeftListViewSelectedItem to object. For binding it's no matter what you return.

Deserialize json multiple array

My classes are defined as:
public class Rootobject
{
public Class1[] Property1 { get; set; }
}
public class Class1
{
public Msys msys { get; set; }
}
public class Msys
{

}
public class Message_Event
{
public string type { get; set; }
public string bounce_class { get; set; }
public string campaign_id { get; set; }
public string customer_id { get; set; }
public string delv_method { get; set; }
public string device_token { get; set; }

In my case this works. You need to tell Newtonsoft.Json what is your destinationt type (array = list):
var des = Newtonsoft.Json.JsonConvert.DeserializeObject<List<Class1>>(json);
This is a simple complete example:

{
string json =

var des = Newtonsoft.Json.JsonConvert.DeserializeObject<List<Class1>>(json);
Console.WriteLine("Done");
Console.ReadLine();

You're coming with the wrong approach. You want to be able not to know what fields the json contains but only that it will be a valid json object that can be parsed.
I'd first recommend you to understand what json object really is and what it can be composed from. You can read it here
Next, you can use this as a json parser.
Documentation about the use can be found here.

Try deserializing to a List<Class1>
var list = JsonConvert.DeserializeObject<List<Class1>>(json);
foreach (Message_Event msg in list.Select(c => c.msys.message_event))
{
Console.WriteLine("campaign: " + msg.campaign_id);
Console.WriteLine("from: " + msg.msg_from);
Console.WriteLine("to: " + msg.rcpt_to);
// etc.
}
Fiddle: https://dotnetfiddle.net/Ei0apw

You can use:
public class Msys
{
public List<Message_Event> message_event { get; set; }
}
And initialize your List<> with
System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<Message_Event>(json);
