C# Json response to model

I have an HTTP call that returns the below, and I am trying to convert the coversio_rates into a returnable model, some of the values get populated, but converio_rates are always null.

string response = apiResponse.Content.ReadAsStringAsync().Result;   
var typetoReturn = JsonConvert.DeserializeObject<Info>(response);

but the values never the set.

API response model example

{
    "result": "success",
    "documetatio": "https: //www.exchagerate-api.com/docs",
    "terms_of_use": "https://www.exchagerate-api.com/terms",
    "time_last_update_uix": 1631266201,
    "time_last_update_utc": "Fri, 10 Sep 2021 09:30:01 +0000",
    "time_ext_update_uix": 1631352601,
    "time_ext_update_utc": "Sat, 11 Sep 2021 09:30:01 +0000",
    "base_code": "USD",
    "coversio_rates": {
        "USD": 1,
        "AED": 3.6725,
        "AF": 81.8475,
        "ALL": 102.7736,
        "AMD": 492.9916,
    }
}

Model Coversio_Rates

public class Coversio_Rates 
{
  
    public float USD { get; set; }
    public float AED { get; set; }
    public float AF { get; set; }
    public float ALL { get; set; }
    public float AMD { get; set; }
}

public class Info
{
    public string result { get; set; }
    public string documetatio { get; set; }
    public string base_code { get; set; }
    public Coversio_Rates Coversio_Rates { get; set; }
}

You need a wrapper class since those properties are child values. For example:

public class Root
{
    public Coversio_Rates Coversio_Rates { get; set; }
    // Add in the other properties if you want them too
}

Now do:

var typetoReturn = JsonConvert.DeserializeObject<Root>(response);

Some other points:

  1. Use decimal instead of string for the currency values
  2. NEVER use .Result, instead you should await the task.
  3. Consider naming your class CoversioRates as that is a more common best practice in C# code. Same goes for the property name, but you will need to add a [JsonProperty("Coversio_Rates")] attribute.
