Getting specific data from JSON Model - c#

Here is my JSON model for trying to get info from Google Maps API. I am trying to get the "name" and "vicinity" from the "Result "class, but am having trouble with getting the data values from the IList, preferably i would like all the name and vicinity attributes to be returned as a string. Anyone got any ideas? Not familiar with using IList's on projects.
public record Location
{
public double lat { get; set; }
public double lng { get; set; }
}
public record Northeast
{
public double lat { get; set; }
public double lng { get; set; }
}
public record Southwest
{
public double lat { get; set; }
public double lng { get; set; }
}
public record Viewport
{
public Northeast northeast { get; set; }
public Southwest southwest { get; set; }
}
public record Geometry
{
public Location location { get; set; }
public Viewport viewport { get; set; }
}
public record OpeningHours
{
public bool? open_now { get; set; }
}
public record Photo
{
public int height { get; set; }
public IList<string> html_attributions { get; set; }
public string photo_reference { get; set; }
public int width { get; set; }
}
public record PlusCode
{
public string compound_code { get; set; }
public string global_code { get; set; }
}
public record Result
{
public string business_status { get; set; }
public Geometry geometry { get; set; }
public string icon { get; set; }
public string icon_background_color { get; set; }
public string icon_mask_base_uri { get; set; }
public string name { get; set; }
public OpeningHours opening_hours { get; set; }
public IList<Photo> photos { get; set; }
public string place_id { get; set; }
public PlusCode plus_code { get; set; }
public double rating { get; set; }
public string reference { get; set; }
public string scope { get; set; }
public IList<string> types { get; set; }
public int user_ratings_total { get; set; }
public string vicinity { get; set; }
}
public record ResourceData
{
public IList<object> html_attributions { get; set; }
public IList<Result> results { get; set; }
public string status { get; set; }
}
public record record_GooglePlacesAPI
{
public DateTime TimeCreated { get; set; } = DateTime.UtcNow;
public ResourceData resourceData { get; set; }
}

Try running a simple LINQ query on the data returned from google API like the following
//string holding google api response
string googleResponse = string.Empty;
var googleapi = JsonConvert.DeserializeObject<record_GooglePlacesAPI>(googleResponse);
//Linq query that returns list of names and vicinities
List<string> vicinities = googleapi.resourceData.results.Select(r => r.vicinity).ToList();
List<string> names = googleapi.resourceData.results.Select(r => r.name).ToList();
it should return you a list of strings holding names and viciniteis

i can't deserialize changeable attribute date on my json api

I am use api use variable date whene date change the object name change like this if i have to get data of this day i use this :https://api.covid19tracking.narrativa.com/api/2020-11-05/country/us
and the result of json object is like this :
and if i have to choose other date i change the date and the variable of date object is change like this if i have to get data of 2020-10-11 ,i calll this:
https://api.covid19tracking.narrativa.com/api/2020-11-05/country/us , and this is image show the result and the change of object date
the problem is if i deserialize the api i get result from , metadata object ,total object , updated_at , and dates object and the other object date and countries give me this error
:NullReferenceException: Object reference not set to an instance of an object
I use https://json2csharp.com/ to get class from json and this is my code :
var client = new RestClient("https://api.covid19tracking.narrativa.com/api/2020-11-05/country/us");
client.Timeout = -1;
var request = new RestRequest(Method.GET);
// request.OnBeforeDeserialization = resp => { resp.ContentType = "application/json"; };
Root response = client.Execute<Root>(request)?.Data;
var paystoday_confirmed = response?.dates.date.countries.US.today_confirmed;
if (paystoday_confirmed != null)
{
Debug.Log("Confirmed :" + paystoday_confirmed);

And this is the error on unity
It will work best if you use dictionaries.
You can make your dates and countries property a dictionary.
dates - Dates needs to be a dictionary because you can get data for different dates so the date will change
countries - The service u are using support other countries. If you change the countries to a dictionary, then the structure below should work for any country, not just for US.
Your code structure will then look something like this:
public class Root
{
public Dictionary<string, Date> dates {get;set;}
public Metadata metadata { get; set; }
public Total total { get; set; }
public string updated_at { get; set; }
}
public class Date
{
public Dictionary<string, Country> countries {get;set;}
public Info info {get;set;}
}
public class Country
{
....
//Country properties here
}
public class Info
{
....
//Info properties here
}
public class Metadata
{
....
//Metadata properties here
}
public class Total
{
....
//Total properties here
}
you should then be able to process the data as follow
foreach(var kvp in root.dates)
{
// the key will be the date eg. '2020-11-05'.
// This you can convert to a date using DateTime.Parse() if you need too.
Console.WriteLine(kvp.Key);
// The value will be the Date object
var dateObj = kvp.Value;
var info = dateObj.info;
foreach(var kvp2 in dateObj.countries)
{
Console.WriteLine(kvp2.Key); // this will be the country eg. 'US'
var countryDetails = kvp2.Value // this will be the Country object
}
}
Or just change your code too:
(note: you will need to know exactly what date was returned)
var paystoday_confirmed = response?.dates["2020-11-05"].countries["US"].today_confirmed;
if (paystoday_confirmed != null)
{
Debug.Log("Confirmed :" + paystoday_confirmed);
}
As already stated in the Comments your main issue here is that you hardcoded
public class Dates
{
[JsonProperty("2020-11-02")]
public _20201102 date { get; set; }
}
But as you can see in your second result the date simply is not 2020-11-02 but rather 2020-10-11!
Therefore in this case there is no object in the json representing the data object => It will be the default reference value null.
So how to solve this?
You could instead use a Dictionary .. however it depends a lot on how your JSON library works. I know that at least with JSON .Net the following should work
public class Root
{
public Dictionary<string, Date> dates { get; set; }
public Metadata metadata { get; set; }
public Total total { get; set; }
public string updated_at { get; set; }
}
public class Date
{
public Dictionary<string, Country> countries { get; set; }
public Info info { get; set; }
}
public class Country
{
public string date { get; set; }
public string id { get; set; }
public List<Link> links { get; set; }
public string name { get; set; }
public string name_es { get; set; }
public string name_it { get; set; }
public List<Region> regions { get; set; }
public string source { get; set; }
public int today_confirmed { get; set; }
public int today_deaths { get; set; }
public int today_new_confirmed { get; set; }
public int today_new_deaths { get; set; }
public int today_new_open_cases { get; set; }
public int today_new_recovered { get; set; }
public int today_open_cases { get; set; }
public int today_recovered { get; set; }
public double today_vs_yesterday_confirmed { get; set; }
public double today_vs_yesterday_deaths { get; set; }
public double today_vs_yesterday_open_cases { get; set; }
public double today_vs_yesterday_recovered { get; set; }
public int yesterday_confirmed { get; set; }
public int yesterday_deaths { get; set; }
public int yesterday_open_cases { get; set; }
public int yesterday_recovered { get; set; }
}
This also sounds more logic since dates indicates that there might be more then one item. And also countries sounds like there might not only be US but also other countries, maybe even multiple entries.
You would then access that e.g. like
foreach(var date in response.dates)
{
foreach(var country in date.value)
{
var paystoday_confirmed = country.value.today_confirmed;
Debug.Log($"Confirmed {paystoday_confirmed} cases for the {date.key} in {country.key}");
}
}
As complete alternative in the case you only need one certain field of your request anyway you could also use SimpleJson (simply copy the provided scripts somewhere into your project) and access them like
var root = JSON.Parse(theJsonString);
var paystoday_confirmed = root["Dates"]["2020-11-05"]["countries"]["US"]["today_confirmed"].AsInt();
For both solutions you will have to get rid of that RestClient package and rather do the UnityWebRequest.Get yourself and use the returned string instead.

Using Json.net to deserialize Json with some changing object names

I'm new here so thanks for the great content; invaluable stuff.
I'm deserializing some Json from TDAmeritrade into a C# desktop app using the "Option Chain" api.
Depending on the input to the api, I can get a response with multiple expiration dates, multiple strike prices, and multiple option objects.
Here's a link to a typical response: API ResponseTDAmeritrade Json Example
A snippet of the problem code:
"numberOfContracts": 8,
"putExpDateMap": {
**"2020-08-21:50": {
"15.0":** [
{
"putCall": "PUT",
"symbol": "FMCI_082120P15",
"description": "FMCI Aug 21 2020 15 Put",
"exchangeName": "OPR",
The problem is that the dates and strike prices change in each response. I've learned that I can deserialize into a "Dictionary<string, List<Type> listName" so I did that in the OptionChain and ExpDate classes but still can't get it working.
Here is the current error: error trace
Here are my classes, created from json2csharp.com but with the date and strike price classes modified:
class OptionChain
{
public string symbol { get; set; }
public string status { get; set; }
public Underlying underlying { get; set; }
public string strategy { get; set; }
public double interval { get; set; }

public int numberOfContracts { get; set; }
public Dictionary<string, List<expDate>> putExpDateMap { get; set; }
public Dictionary<string, List<expDate>> callExpDateMap { get; set; }
public class expDate
{
public Dictionary<string, List<StrikePrice>> strikePrices { get; set; }
}

public OptionDeliverablesList optionDeliverablesList { get; set; }
public double strikePrice { get; set; }
public long expirationDate { get; set; }
public int daysToExpiration { get; set; }
public string expirationType { get; set; }
public long lastTradingDay { get; set; }
public double multiplier { get; set; }
public string settlementType { get; set; }
public string deliverableNote { get; set; }
public bool isIndexOption { get; set; }
public double percentChange { get; set; }
public double markChange { get; set; }
public double markPercentChange { get; set; }
public bool inTheMoney { get; set; }
public bool mini { get; set; }
public bool nonStandard { get; set; }
public class OptionDeliverablesList
{
public string symbol { get; set; }
public string assetType { get; set; }
public double deliverableUnits { get; set; }
public string currencyType { get; set; }
}
Am I doing something wrong in the Dictionaries? The way I understand it from my many hours of reading, the expiration dates and strike prices need to be read anonymously.
Thanks a bunch!
If I get your problem right - you have probelms deserializing json structure where keys are dynamic values but not static property names, correct? If so- you have modeled incorrect POCO (there are two nested dictionaries).
POCOs below give correct deserialization results (rest of properties skipped)
class OptionChain
{
public string Symbol { get; set; }
public string Status { get; set; }
public Dictionary<string, Dictionary<string, ExpDate[]>> PutExpDateMap { get; set; }
public Dictionary<string, Dictionary<string, ExpDate[]>> CallExpDateMap { get; set; }
//other properties ignored because dont matter
}
class ExpDate
{
public string ExchangeName { get; set; }
public decimal Bid { get; set; }
public decimal Ask { get; set; }
//other properties ignored because dont matter
}
Tested POCOs with json sample provided in your post:
static void Main(string[] args)
{
var t = File.ReadAllText("test.json");
var r = JsonConvert.DeserializeObject<OptionChain>(t);
Console.WriteLine($"Total elements in {nameof(r.PutExpDateMap)} : {r.PutExpDateMap.Count()}");
Console.WriteLine($"Keys in {nameof(r.PutExpDateMap)} : {string.Join(",", r.PutExpDateMap.Keys)}");
Console.WriteLine($"Total elements in {nameof(r.CallExpDateMap)} : {r.CallExpDateMap.Count()}");
Console.WriteLine($"Keys in {nameof(r.CallExpDateMap)} : {string.Join(",", r.CallExpDateMap.Keys)}");
}
Application output is:

Nested JSON failed to deserialize

This is the link for my nested JSON
: -
https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=1500&type=restaurant&keyword=cruise&key=AIzaSyDk8ZfHO__XrYfDGi9RnFA_WxlVmRW5HMI
i have generated a model class which has to give me the list of names , later i populate them in a RecyclerView.
using System;
using System.Collections.Generic;
namespace newApp.Model
{
public class Location
{
public double lat { get; set; }
public double lng { get; set; }
}
public class Northeast
{
public double lat { get; set; }
public double lng { get; set; }
}
public class Southwest
{
public double lat { get; set; }
public double lng { get; set; }
}
public class Viewport
{
public Northeast northeast { get; set; }
public Southwest southwest { get; set; }
}
public class Geometry
{
public Location location { get; set; }
public Viewport viewport { get; set; }
}
public class OpeningHours
{
public bool open_now { get; set; }
}
public class Photo
{
public int height { get; set; }
public List<string> html_attributions { get; set; }
public string photo_reference { get; set; }
public int width { get; set; }
}
public class PlusCode
{
public string compound_code { get; set; }
public string global_code { get; set; }
}
public class Result
{
public Geometry geometry { get; set; }
public string icon { get; set; }
public string id { get; set; }
public string name { get; set; }
public OpeningHours opening_hours { get; set; }
public List<Photo> photos { get; set; }
public string place_id { get; set; }
public PlusCode plus_code { get; set; }
public double rating { get; set; }
public string reference { get; set; }
public string scope { get; set; }
public List<string> types { get; set; }
public string vicinity { get; set; }
}
public class RootObject
{
public List<object> html_attributions { get; set; }
public List<Result> results { get; set; }
public string status { get; set; }
}
}
Then , in this method i tried to deserialize the data , i want to get a list of icon, name , id and location.
This is the method i initially have :
public async void getData()
{
var content = await _client.GetStringAsync(URL);
var n = JsonConvert.DeserializeObject<List<List<Result>>>(content);
Debug.WriteLine("Output ", n);
}
Try to deserialize to the RootObject class directly:
JsonConvert.DeserializeObject<RootObject>(content);
And then retrieve all data you need using LINQ.
Declare ResultHeadInfo class which will contain fields you need:
public class ResultHeadInfo
{
public Location Location { get; set; }
public string Name { get; set; }
public string Id { get; set; }
public string Icon { get; set; }
}
Then write LINQ query to get data:
var root = JsonConvert.DeserializeObject<RootObject>(content);
List<ResultHeadInfo> infoList = root.results.Select(x => new ResultHeadInfo {
Location = x.geometry.location,
Name = x.name,
Id = x.id,
Icon = x.icon
}).ToList();
By the way, you can use just Location object instead of Northest and Southwest as they are identical.
public class Viewport
{
public Location northeast { get; set; }
public Location southwest { get; set; }
}
In addition to the other answer, don't forget you can use attributes to identify the fields but keep the property names consistent with the usual naming conventions:
public partial class Viewport
{
[JsonProperty("northeast")]
public Location Northeast { get; set; }
[JsonProperty("southwest")]
public Location Southwest { get; set; }
}
I created those same classes recently for my project, and used quicktype.io to generate them. Much better output than the usual 'Paste Special' built into VS.

GeoJson c# example parse countries in the world and generate Geojson for each country

Looking for an example of how to parse / deserialize Geojson files using geojson.net. for some reason there are no examples of how to use the geojson.net package.
I would like to use this on my site with the google maps api. currently I use polygon shapes but want to move towards using geojson objects for the layers as this seems to be a better format.
using c# I would like to serialize Geojson, select specific country borders and generate a new geojson file that can be references and added to google maps as a layer.
to test this I created a colsole app to try to deserilaize the GeoJson, this does not work (please could you give me some direction on the correct way to deserialize Geojson ?)
static void Main(string[] args)
{
string Jsonstring = File.ReadAllText("c:/worldborders.json");
JavaScriptSerializer ser = new JavaScriptSerializer();
List<GeoJsonProperties> ns = (List<GeoJsonProperties>)ser.Deserialize(Jsonstring, typeof(List<GeoJsonProperties>));
?ns is Empty?
}
I created a class for the geojson file using the online generator http://json2csharp.com/ (I had thought that GeoJson.net would include the class as its a standard) , GeoJsonProperties,
public class GeoJsonProperties
{
public int scalerank { get; set; }

GeoJSON.Net works with Newtonsoft.Json. you can deserialize the same way you would using that library.
var geoJsonObject = JsonConvert.DeserializeObject<Point>(json);
For deserializing a FeatureCollection object (like the one you mention in the question) using the GeoJSON.Net library use the following code :
var collection = JsonConvert.DeserializeObject<FeatureCollection>(json);

Error with deserializing complex Json

I deserialize complex JSON (Spotify Playlist) and get root level values but I cannot get branches values. I Google problem, try different options without success but, I assume its silly mistake or lack of knowledge so therefore just ask for help what I am missing?
My classes are:
public class Playlist
{
public string collaborative { get; set; }
public string description { get; set; }
//public <ExternalUrls> external_urls { get; set; } //object
//public List<Followers> followers { get; set; } //object
public string href { get; set; }
public string id { get; set; }
//public List<Image> images { get; set; } //array
public string name { get; set; }
}
public class Tracks
{
public string href { get; set; }
public Item items { get; set; } //object
public string limit { get; set; }
public string next { get; set; }
public string offset { get; set; }
public string previous { get; set; }
public string total { get; set; }
}
And code to deserialize looks like that:
StreamReader responseFromServer = new StreamReader(myWebResponse.GetResponseStream());
var dataResponse = responseFromServer.ReadToEnd();
responseFromServer.Close();
var elements = new JavaScriptSerializer().Deserialize<Playlist>(dataResponse);
RootBuffer.AddRow();
RootBuffer.collaborative = elements.collaborative.ToString();
foreach (Tracks trs in elements.tracks)
{
TracksBuffer.AddRow();
TracksBuffer.href = trs.href.ToString()
}
I genereated the classes using this excellent site: json2csharp.com
And used your existing deserialization code successfully with the following classes. It populated all the data including the child collections (brace yourself, it's a long one):
public class Playlist
{
public bool collaborative { get; set; }

}
Hope this helps.
