JSON deserialization not deserializing?

JSON deserialization not deserializing? - c#

I am bit new to the serialization/deserialization of JSON's strings. I have tried to use Newtonsoft.Json. The thing is I got JSON string received from
url : http://epguides.frecar.no/show/gameofthrones/ and I would like to create and class objects from it. So later I could print it out...
I found out how to generate classes from your JSON string, by copying the string and Edit>Paste_Special>Paste_JSON_as_Classes so that should be alright.
Generated classes:
namespace TvSeries
{
public class Show
{
public string title { get; set; }
public string imdb_id { get; set; }
public string epguide_name { get; set; }
}
public class __invalid_type__1
{
public Show show { get; set; }
public string title { get; set; }
public int number { get; set; }
public int season { get; set; }
public string release_date { get; set; }
}
public class Show2
{
public string title { get; set; }
public string imdb_id { get; set; }
public string epguide_name { get; set; }
}
public class __invalid_type__2
{
public Show2 show { get; set; }
public string title { get; set; }
public int number { get; set; }
public int season { get; set; }
public string release_date { get; set; }
}
public class Show3
{
public string title { get; set; }
public string imdb_id { get; set; }
public string epguide_name { get; set; }
}
public class __invalid_type__3
{
public Show3 show { get; set; }
public string title { get; set; }
public int number { get; set; }
public int season { get; set; }
public string release_date { get; set; }
}
public class Show4
{
public string title { get; set; }
public string imdb_id { get; set; }
public string epguide_name { get; set; }
}
public class __invalid_type__4
{
public Show4 show { get; set; }
public string title { get; set; }
public int number { get; set; }
public int season { get; set; }
public string release_date { get; set; }
}
public class Show5
{
public string title { get; set; }
public string imdb_id { get; set; }
public string epguide_name { get; set; }
}
public class __invalid_type__5
{
public Show5 show { get; set; }
public string title { get; set; }
public int number { get; set; }
public int season { get; set; }
public string release_date { get; set; }
}
public class Show6
{
public string title { get; set; }
public string imdb_id { get; set; }
public string epguide_name { get; set; }
}
public class __invalid_type__6
{
public Show6 show { get; set; }
public string title { get; set; }
public int number { get; set; }
public int season { get; set; }
public string release_date { get; set; }
}
public class Show7
{
public string title { get; set; }
public string imdb_id { get; set; }
public string epguide_name { get; set; }
}
public class __invalid_type__7
{
public Show7 show { get; set; }
public string title { get; set; }
public int number { get; set; }
public int season { get; set; }
public string release_date { get; set; }
}
public class RootObject
{
public List<__invalid_type__1> __invalid_name__1 { get; set; }
public List<__invalid_type__2> __invalid_name__2 { get; set; }
public List<__invalid_type__3> __invalid_name__3 { get; set; }
public List<__invalid_type__4> __invalid_name__4 { get; set; }
public List<__invalid_type__5> __invalid_name__5 { get; set; }
public List<__invalid_type__6> __invalid_name__6 { get; set; }
public List<__invalid_type__7> __invalid_name__7 { get; set; }
}
}
Here is simple main class to print it out to the console:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using System.Web.Script.Serialization;
using Newtonsoft.Json;
namespace TvSeries
{
class Program
{
static void Main(string[] args)
{
using (WebClient wc = new WebClient())
{
var json = wc.DownloadString("http://epguides.frecar.no/show/gameofthrones/");
//Console.WriteLine(json);
RootObject obj = JsonConvert.DeserializeObject<RootObject>(json);
foreach (var item in obj.__invalid_name__1)
{
Console.WriteLine("Show: {0}, release date: {1}", item.show.title, item.release_date);
}
Console.ReadKey();
}
}
}
}
So the actual question is why is not deserializing or working properly, because the objects are still null? I am missing something important? I have also tried JavaScriptSerializer() but it doesn't fix my problem.

You use an attribute like this:
[JsonProperty("show")]
public Show2 Show2 { get; set; }

As user3791372 said, you should tidy up the generated classes. However these classes where generated because the response looks like this
{ "1":[{...}...], "2":[{...}...],...}. So you first need to get rid of "1", "2" and define your own types for clean code. the result will look like this
class Show
{
public string title { get; set; }
public string imdb_id { get; set; }
public string epguide_name { get; set; }
}
class Episode
{
public Show show { get; set; }
public string title { get; set; }
public int number { get; set; }
public int season { get; set; }
public DateTime release_date { get; set; }
}
class Program
{
static void Main(string[] args)
{
using (WebClient wc = new WebClient())
{
//download json string
var json = wc.DownloadString("http://epguides.frecar.no/show/gameofthrones/");
//convert json to dynamic object
JObject obj = JObject.Parse(json);
//create an array that have as many elements as the children of obj => {"1", "2", "3", ...}
JArray[] results = new JArray[obj.Children().Count()];
//fill the array with the children of obj => results[6] = "[{"show": {"title": "Game of Thrones", "imdb_id": "tt0944947", "epguide_name": "gameofthrones"}, "title": "TBA", "number": 1, "season": 7, "release_date": "2017-06-25"}]"
for (int i = 0; i < results.Length; i++)
{
results[i] = (JArray)obj[(i + 1).ToString()];
}
//deserialize each item in results to List<Episode> if you checked the response it returns arrays of episodes
List<List<Episode>> seasons = new List<List<Episode>>(results.Length);
foreach (var item in results)
{
seasons.Add(JsonConvert.DeserializeObject<List<Episode>>(item.ToString()));
}
//output the result
foreach (var season in seasons)
{
foreach (var episod in season)
{
Console.WriteLine("Show: {0}, release date: {1}", episod.show.title, episod.release_date);
}
}
Console.ReadKey();
}
}
}

Consuming web API into Blazor

I'm trying to consume a web API into Blazor but am struggling to extract certain information from the API
using System.Text.Json;
namespace CA3.Song
{
public class SongService : ISongService
{
private readonly HttpClient _httpClient;
const string _baseUrl = "https://genius-song-lyrics1.p.rapidapi.com/";
const string _songEndpoint = "songs/chart?time_period=day&chart_genre=all&per_page=10&page=1";
const string _host = "genius-song-lyrics1.p.rapidapi.com";
const string _key = "{key}";
public SongService(HttpClient httpClient)
{
_httpClient = httpClient;
}
public async Task<List<SongItem>> GetSong()
{
Configure();
var response = await _httpClient.GetAsync(_songEndpoint);
var response_outcome = response.EnsureSuccessStatusCode;
using var stream = await response.Content.ReadAsStreamAsync();
var dto = await JsonSerializer.DeserializeAsync<SongDto>(stream);
return dto.response.chart_items.Select(n => new SongItem { Artist = n.item.primary_artist, Title = n.item.primary_title, ReleaseDate = n.primary_release_date }).ToList().T ;
}
private void Configure()
{
_httpClient.BaseAddress = new Uri(_baseUrl);
_httpClient.DefaultRequestHeaders.Add("X-RapidAPI-Host", _host);
_httpClient.DefaultRequestHeaders.Add("X-Rapid-Key", _key);
}
}
}
The issue is on the return statement using LINQ.

Above is the JSON file and I'm trying to extract the artist name, song title and release date from Item but it isn't in a list so I'm trying to find a way to extract this info using LINQ. Any help would be greatly appreciated !

I think you misinterpreted the declaration of the JSON. They are stored in an array Chart_Items[] chart_items thus you may use linq.
There are many ways to do this, I took advantage of named tuples in modern C# paired with linq.
Response r = new Response();//some resonse from api
var results = r.chart_items.Select(i => (i.item.artist_names, i.item.title, i.item.release_date_components)).ToList();
foreach(var result in results)
{
string artist_names = result.artist_names;
string title = result.title;
Release_Date_Components release_date_components = result.release_date_components;
}

Cannot deserialize the current JSON in C#

I faced the problem: Cannot deserialize the current JSON object.
As follows:
public List<Track> Tracks { get; set; }
public async Task<List<Track>> GetTracking()
{
using (var httpClient = new HttpClient())
{
using (var requests = new HttpRequestMessage(new HttpMethod("GET"), "urlxxxxxxxx..."))
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
requests.Headers.TryAddWithoutValidation("accept", "application/json");
var response = await httpClient.SendAsync(requests);
using (HttpContent content = response.Content)
{
var jsonStr = content.ReadAsStringAsync().GetAwaiter().GetResult();
var res = JsonConvert.DeserializeObject<List<Track>>(jsonStr); //Get Error**
Tracks = res;
}
}
}
return Tracks;
}

My input data:
https://drive.google.com/file/d/12g0nHkHlmbU4Af8crHlzKXD_ERIZdCyH/view?usp=sharing
As in my description. I get the error: I get the error: Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[XX. Models.Track]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
Even though I declared: public List events { get; set; }
Is the problem I have misunderstood the format of DeserializeObject. Looking forward to everyone's help. Thank

you have an object, not an array
var res = JsonConvert.DeserializeObject<Track>(jsonStr);
and fix class
public class Events
{
....
public List<DocumentReferencesMearsk> documentReferences { get; set; }
public TransportCallMaersk transportCall { get; set; }
}

Your model is incomplete and has typos. Assuming you have the correct versions of them.
You are doing:
var res = JsonConvert.DeserializeObject<List<Track>>(jsonStr);
which should be just:
var res = JsonConvert.DeserializeObject<Track>(jsonStr);
Your json doesn't have an array at the root level.
Full working sample:
void Main()
{
var res = JsonConvert.DeserializeObject<Track>(myJson);

EDIT: Result is something like:

App is freezing when trying to deserialize Json string to object

I'm not sure what is causing this to happen. When debugging, I can step through each line, but when it hits the DeserializeObject line, the program doesn't do anything. I can no longer step over or do anything else with the program. No error messages are being thrown either.

As mentioned in a comment your class definition doesn't seem to match the JSON response, assuming you're using Visual Studio it's probably worth opening Debug / Windows / Exception Settings and make sure "Common Language Runtime Exceptions" is checked. Sometimes I've found stepping over in multi-threaded apps can produce unusual results after an exception.
When I pasted your code into LINQPad I got errors on several members you've defined as List<string> when the underlying type is more complex. What I normally do to avoid those errors is copy the raw json from a browser window to the clipboard and with a CS file open in Visual Studio do an Edit / Paste Special / Paste JSON as classes to automatically create the classes. After doing that I got the following that deserialized the data fine:
async Task Main()
{
await LookupMonsterStats("aboleth");
}
public async Task LookupMonsterStats(string name)

monster.Dump();

C# Deserialize json api response

hey i want to Deserialize this json API response to get values including profile state etc for processing in the program.
i tried multiple ways from different questions in here but i get response as null.
here is the code, correct me what i am doing wrong please
{
"response": {
"players": [{
"steamid": "xxxxxxxxxxxxxxxxx",
"communityvisibilitystate": 3,
"profilestate": 1,
"personaname": "xxxx xxxx",
"lastlogoff": 1529478555,
"commentpermission": 1,
"profileurl": "xxxxxxxxxxxxxxx",
"avatar": "xxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"avatarmedium": "xxxxxxxxxxxxxxxxxxxxx",
"avatarfull": "xxxxxxxxxxx",
"personastate": 1,
"realname": "xxxx",
"primaryclanid": "xxxxxxxxxx",
"timecreated": 1097464215,
"personastateflags": 0
}]
}
}
The code i tried
public class AccountInfo
{
public string steamid { get; set; }
public int communityvisibilitystate { get; set; }
public int profilestate { get; set; }
public string personaname { get; set; }
public ulong lastlogoff { get; set; }
public int commentpermission { get; set; }
public string profileurl { get; set; }
public string avatar { get; set; }
public string avatarmedium { get; set; }
public string avatarfull { get; set; }
public int personastate { get; set; }
public string realname { get; set; }
public string primaryclanid { get; set; }
public ulong timecreated { get; set; }
public int personastateflags { get; set; }
}
public class Response
{
public AccountInfo response { get; set; }
}
public class Response1
{
public Response players { get; set; }
}
static void Main(string[] args)
{
DeserilizeJson();
}
internal static void DeserilizeJson()
{
string json = GetUrlToString("http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=xxxxxxxxxxxxxxxxxxxxx&steamids=xxxxxxxxxxxxxxx");
Console.WriteLine(json);
Response1 info = JsonConvert.DeserializeObject<Response1>(json);
using (StreamWriter file = File.CreateText(#"c:\test.json"))
{
JsonSerializer serializer = new JsonSerializer();
serializer.Serialize(file, info);
}
}
internal static string GetUrlToString(string url)
{
String Response = null;
try
{
using (WebClient client = new WebClient())
{
Response = client.DownloadString(url);
}
}
catch (Exception)
{
return null;
}
return Response;
}

Use this as a Model Class
using System;
using System.Collections.Generic;
using System.Globalization;
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
public partial class JsonModel
{
[JsonProperty("response")]
public Response Response { get; set; }
}
public partial class Response
{
[JsonProperty("players")]
public List<Player> Players { get; set; }
}
public partial class Player
{
[JsonProperty("steamid")]
public string Steamid { get; set; }
[JsonProperty("communityvisibilitystate")]
public long Communityvisibilitystate { get; set; }
[JsonProperty("profilestate")]
public long Profilestate { get; set; }
[JsonProperty("personaname")]
public string Personaname { get; set; }
[JsonProperty("lastlogoff")]
public long Lastlogoff { get; set; }
[JsonProperty("commentpermission")]
public long Commentpermission { get; set; }
[JsonProperty("profileurl")]
public string Profileurl { get; set; }
[JsonProperty("avatar")]
public string Avatar { get; set; }
[JsonProperty("avatarmedium")]
public string Avatarmedium { get; set; }
[JsonProperty("avatarfull")]
public string Avatarfull { get; set; }
[JsonProperty("personastate")]
public long Personastate { get; set; }
[JsonProperty("realname")]
public string Realname { get; set; }
[JsonProperty("primaryclanid")]
public string Primaryclanid { get; set; }
[JsonProperty("timecreated")]
public long Timecreated { get; set; }
[JsonProperty("personastateflags")]
public long Personastateflags { get; set; }
}
Then do this in your Main Class
var info = JsonConvert.DeserializeObject<JsonModel>(json);
var Response = info.Response

Open nuget, search newtonsoft.json and install.
Deserialize:
var deserialized = JsonConvert.DeserializeObject(jsonstring);

Try this:
public class Player
{
public string steamid { get; set; }
public int communityvisibilitystate { get; set; }
public int profilestate { get; set; }
public string personaname { get; set; }
public ulong lastlogoff { get; set; }
public int commentpermission { get; set; }
public string profileurl { get; set; }
public string avatar { get; set; }
public string avatarmedium { get; set; }
public string avatarfull { get; set; }
public int personastate { get; set; }
public string realname { get; set; }
public string primaryclanid { get; set; }
public ulong timecreated { get; set; }
public int personastateflags { get; set; }
}
public class Response
{
public Player[] players { get; set; }
}
public class EncapsulatedResponse
{
public Response response {get;set;}
}
internal static void DeserilizeJson()
{
string json = GetUrlToString("http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=xxxxxxxxxxxxxxxxxxxxx&steamids=xxxxxxxxxxxxxxx");
Console.WriteLine(json);
EncapsulatedResponse info = JsonConvert.DeserializeObject<EncapsulatedResponse>(json);
using (StreamWriter file = File.CreateText(#"c:\test.json"))
{
JsonSerializer serializer = new JsonSerializer();
serializer.Serialize(file, info);
}
}

The players property should be a list of players as it is an array . Below is the Correct Model
public class Player
{
public string steamid { get; set; }
public int communityvisibilitystate { get; set; }
public int profilestate { get; set; }
public string personaname { get; set; }
public int lastlogoff { get; set; }
public int commentpermission { get; set; }
public string profileurl { get; set; }
public string avatar { get; set; }
public string avatarmedium { get; set; }
public string avatarfull { get; set; }
public int personastate { get; set; }
public string realname { get; set; }
public string primaryclanid { get; set; }
public int timecreated { get; set; }
public int personastateflags { get; set; }
}
public class Response
{
public List<Player> players { get; set; }
}

You need to change the object structure:
public class Response
{
public AccountInfo[] players { get; set; }
}
public class Response1
{
public Response response { get; set; }
}
then deserialize Response1 (like u do currently)

Just to provide a different approach, you can use JObject (Newtonsoft.Json.Linq) so that you only need the AccountInfo class:
var accounts = JObject.Parse(json).Root
.SelectToken("response.players")
.ToObject(typeof(AccountInfo[]));
Or in some cases, it is even easier just navigating the properties:
var accounts = JObject.Parse(json)["response"]["players"]
.ToObject((typeof(AccountInfo[])));

Generate C# object from Json string and parse Json string to generated object

I am trying to generate C# class using the JSON string from here http://json2csharp.com/ this works fine. But I can't parse the JSON to the object generated by the website.
Here is the JSON string
{
"searchParameters":{
"key":"**********",
"system":"urn:oid:.8"
},
"message":" found one Person matching your search criteria.",
"_links":{
"self":{
"href":"https://integration.rest.api.test.com/v1/person?key=123456&system=12.4.34.."
}
},
"_embedded":{
"person":[
{

"end":"9999-12-31T23:59:59Z"
}
}
],

{

"family":["BC"],
"given":["TWO"],
"period":{
"start":"9999-10-22T00:00:00Z",

}
}

}
}
],
"photo":[
{
"content":{
"contentType":"image/jpeg",

},

},
"personLink":{

"personMatch":{
"href":"https://integration.rest.api.commonwellalliance.org/v1/person/-182d-4296-90cc-/personMatch?orgId="
}
}
}
]
}
}
Here is the code I use to convert to the object.
JavaScriptSerializer js = new JavaScriptSerializer();
var xx = (PersonsearchVM)js.Deserialize(jsonstr, typeof(PersonsearchVM));
Is there any other wat to generate the object and parse?

I think you have some invalid characters in your JSON string. Run it through a validator and add the necessary escape characters.
http://jsonlint.com/

You aren't casting it to the right object. Cast it to the type RootObject.
Eg
JavaScriptSerializer js = new JavaScriptSerializer();
var xx = (RootObject)js.Deserialize(jsonstr, typeof(RootObject));
The code that json 2 csharp creates is this:
public class SearchParameters
{
public string key { get; set; }

The following function will convert JSON into a C# class where T is the class type.
public static T Deserialise<T>(string json)
{
T obj = Activator.CreateInstance<T>();
using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
obj = (T)serializer.ReadObject(ms); //
return obj;
}
}
You need a reference to the System.Runtime.Serialization.json namespace.
The function is called in the following manner;
calendarList = Deserialise<GoogleCalendarList>(calendarListString);
calendarlist being the C# class and calendarListString the string containing the JSON.

JSON deserialization not deserializing? - c#

You use an attribute like this: [JsonProperty("show")] public Show2 Show2 { get; set; }
