Why can't I deserialize string Into a model?

I'm using a HTTP client to get a string and picking out my json from that and converting back to a string to deserialize it into a List of "Spots" but can't get it to to work
I've tried changing the DeserializeObject type to every mix of "List, IList, HardwareUpdateSpot, HardWareModel" and still it didn't work
public async Task<IList<HardwareUpdateSpot>> UpdateSpotHTTP()
{
var client = new HttpClient();
var response = await client.GetAsync(
"https://io.adafruit.com/api/v2/Corey673/feeds/673d855c-9f66-4e49-8b2c-737e829d880c");
var responseHTTP = response.Content.ReadAsStringAsync();
var j = JObject.Parse(responseHTTP.Result);
var b = j.GetValue("last_value");
var h = b.ToString();
var dataObjects = JsonConvert.DeserializeObject<IList<HardwareUpdateSpot>>(h);
return null;
}
public record HardWareModel
{
public int SpotId { get; set; }
public string Occupied { get; set; }
}
public class HardwareUpdateSpot
{
public IList<HardWareModel> Spots { get; set; }
public HardwareUpdateSpot(IList<HardWareModel> spots)
{
Spots = spots;
}
}

While trying to reproduce your problem I have examined the returned value from the API call. This is the json returned:
{"Spot":[
{"SpotId":"1","Occupied":"false",},
{"SpotId":"2","Occupied":"false",},
{"SpotId":"3","Occupied":"false",},
{"SpotId":"4","Occupied":"false"}
]}
So, it easy to see that the returned json requires a root object with a public Spot property (not Spots) and this property should be a collection.
Instead the code above expects a json that has at the root level a collection of HardwareUpdateSpot and of course it cannot work.
To fix the problem you need to change the deserialization to:
JsonConvert.DeserializeObject<HardwareUpdateSpot>(h);
Now, you need to make some changes to the HardwareUpdateSpot class to make it compatible with the json.
First you need to add a parameterless constructor required by jsonconvert, then you need to fix the difference between the name for the property (Spots) and the name returned (Spot).
So you can change the property name to match the json or add the attribute that make Spots=Spot
[JsonProperty("Spot")]
public IList<HardWareModel> Spots { get; set; }

C# .net http | How to get objects layers deep from API

I learned how to get information from an API using the microsoft docs, the microsoft docs don't show how to get nested/layers deep objects. The only video I found that showed how to do it did it something like this. However I can't get it to work, receiving only an error stating this:
"Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Dashboard.Weather' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly."
Any help is appreciated, i'm trying to get the "Weather.description", here's my sample code:
public class Weather
{
public string Description{ get; set; }
}
public class Product
{
public Weather Weather { get; set; }
}
public static class ApiHelper
{
static string city_id = "CITY_ID";
static string api_key = "API_KEY";
public static HttpClient client = new HttpClient();
public static void InitializeClient()
{
client.BaseAddress = new Uri($"http://api.openweathermap.org/data/2.5/weather?id={city_id}&APPID={api_key}");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
}
public static async Task<Weather> GetProductAsync()
{
Product product = null;
HttpResponseMessage response = await client.GetAsync("");
if (response.IsSuccessStatusCode)
{
product = await response.Content.ReadAsAsync<Product>();
}
return product.Weather;
}
}
async void SetLabelText()
{
var weather = await ApiHelper.GetProductAsync();
descriptionLabel.Text = $"Description: {weather.Description}";
}
The response from the API is formatted as follows
{"coord":{"lon":-89.59,"lat":41.56},"weather":[{"id":800,"main":"Clear","description":"clear sky","icon":"01d"}],"base":"stations","main":{"temp":279.27,"feels_like":275.4,"temp_min":278.15,"temp_max":280.37,"pressure":1027,"humidity":74},"visibility":16093,"wind":{"speed":3.1,"deg":200},"clouds":{"all":1},"dt":1576951484,"sys":{"type":1,"id":3561,"country":"US","sunrise":1576934493,"sunset":1576967469},"timezone":-21600,"id":4915397,"name":"Walnut","cod":200}

Your Product model does not correctly align with the json you are receiving.
The json you've post has weather as a list, but Product assumes it will just be an object. The json parser, then, correctly fails when seeing it is an array in the actual json instead of a JSON object.
The fix should be simple; Product.Weather should be of type List<Weather> (or IEnumerable<Weather> or Weather[], whichever fits your needs).

parse json response c#

I have created small class
class JsonResponse
{
public string Response { get; set; }
}
Then in my program I send some json data and wait store reply to the following variable
var ResultJSON = Post(uri, values);
while parsing I get
Service Error: Cannot convert object of type 'System.String' to type
'App.someclass+JsonResponse'

using Newtonsoft.Json;
class JsonResponse
{
public string Response { get; set; }
}
class Utility
{
public JsonResponse JsonDeserialisation(string response)
{
TextReader textReader = new StreamReader(response);
JsonTextReader jsonReader = new JsonTextReader(textReader);
return JsonSerializer.CreateDefault().Deserialize<JsonResponse>(jsonReader);
}
}
class Main
{
static void Program()
{
var ResultJSON = "Json String received from post";//Post(uri, values);
var deserialisedJson = Utility.JsonDeserialisation(ResultJSON);
}
}
Add newtonSoft.json nuget package to project

try
var Result = new JavaScriptSerializer().Deserialize<JsonResponse>(ResultJSON.**Response**);
looks to me that you are trying to deserialize from an object rather than the string response

Try this, may give your JSON file to result variable.
var result = Convert.ToString(ResultJSON);

Try using using newtonsoft.json downloadable here or use the nuget package.
It has a function that does exactly what you want. Expecting the result of the Post is in string format of course.
var result = JsonConvert.DeserializeObject<JsonResponse>(ResultJSON);
Your JsonResponse class must look exacly the same as the json your getting. So make sure if you get more data in the json that you want to save in the class the names are the same.
If you have anymore questions feel free to ask.

Cannot deserialize RestResponse with RestSharp C#

I am trying to deserialize JSON to C# object but not able to get rid of this compiler error. Any help would be much appreciated.
JSON
{
AX:{BX:1777}
}
Here are my deserializer classes:
Response.cs
{
public class Response
{
public AX Ax { get; set; }
}
}
AX.cs
{
public class AX
{
public long Bx { get; set; }
}
}
Here is the line that is problematic:
IRestResponse<Response> response = client.Execute<Response>(request);
response.Content is just as fine and returns the raw JSON but I want it to be an instance of the Response class. I want to access Bx like this:
var price = response.Ax.Bx; // should return 1777
But this line produces the following compiler error:
Error: IRestResponse does not contain definition for 'Ax'

For what it's worth, and having spent some time searching around this, I would have used Newtonsoft.Json and solved it like this:
IRestResponse response = client.Execute(request);
string ResponseStr = response.Content.ToString();
dynamic Response = JsonConvert.DeserializeObject<dynamic>(ResponseStr);
you can then call off the elements as you need them:
var price = Response.AX.BX;
string Description = Response.AX.Desc.ToString(); etc
Hope this helps someone

Problem is with case sensitive. RestSharp serializer expects following json structure
{
Ax:{Bx:1777}
}
You have 3 ways to deal with it:
1) add DataContract and DataMember to your classes
[DataContract]
public class Response
{
[DataMember(Name = "AX")]
public AX Ax { get; set; }
}
[DataContract]
public class AX
{
[DataMember(Name = "BX")]
public long Bx { get; set; }
}
2) write your own serializer that ignores case sensitive and use it with restsharp
3) change your json structure

c# multi level json

I am trying to make a simple program that can automate price checking using data from json, however I haven't used json before and I'm not quite sure what I need to do get get the desired result.
Effectively I'm trying to convert this PHP into c#. (http://www.sourcecodester.com/tutorials/php/8042/api-json-parsing-php.html)
<?php
$src = file_get_contents('https://www.g2a.com/marketplace/product/auctions/?id=256');
$json = json_decode($src, true);
foreach ($json as $k=>$v) {
if (is_array($v)) {
foreach($v as $key=>$value) {
if (is_array($value)) {
foreach($value as $arKey => $arValue) {
if ($arKey == 'p') {
echo $arValue . '<br/>';
}
}
}
}
}
}
?>
I've tried a few things such as JsonConvert.DeserializeObject(webJson) and JObject.Parse(webJson), but I'm just not sure where I should be looking or how to go about doing it.
I have the first part:
internal static string GetWebContent(string #ID)
{
var wc = new WebClient();
string response = wc.DownloadString(#"https://www.g2a.com/marketplace/product/auctions/?id=" + #ID);
return response;
}
A response looks like this: (https://www.g2a.com/marketplace/product/auctions/?id=27446)

Thanks in advace

So Json is a way for two languages to pass objects to each other. It's just a way to encode an object, so the first part would be to create an object that matches the Json encoding. I was unable to see your example, so I will give you one of my own.
{"Aggregates": [{"ColumnName": "Some Value", "AggregateFunction": "Some Other Value"}], "GroupBy": true}
I would then create a class like this one.
public class JsonAggregates
{
public List<Aggregate> Aggregates { get; set; }
public string GroupBy { get; set; }
}
public class Aggregate
{
public string ColumnName {get; set;}
public string AggregateFunction {get; set;}
}
You can then encode the Json to this new data type with the following code.
using (Stream s = GenerateStreamFromString(json))
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(JsonAggregates));
JsonAggregates aggregate = (JsonAggregates)serializer.ReadObject(s);
}
