how to map complex json data into model class

about project: I am using following free api to get weather data. I am able to create Model class and map basic values and its working ok.

Question: But how do I map more complex values like hourly_units, which had sub parameters like time & temperature_2m. same thing about hourly which also has arrays of time & temperature_2m. Do I have to create multi Model class? or can this be doing with List?

public class WeatherModel
{
    public long latitude { get; set; }
    public long longitude { get; set; }
    public long generationtime_ms { get; set; }
    public long utc_offset_seconds { get; set; }

    public string timezone { get; set; }
    public string timezone_abbreviation { get; set; }
    public string elevation { get; set; }
}

JSON return is in following format:

>Solution :

have you tried creating them as sub classes

public class WeatherModel
{
    public long latitude { get; set; }
    public long longitude { get; set; }
    public long generationtime_ms { get; set; }
    public long utc_offset_seconds { get; set; }

    public string timezone { get; set; }
    public string timezone_abbreviation { get; set; }
    public string elevation { get; set; }
    
    Public class Hourly_Units {
         public string time { get; set; }
         public string temperature_2m { get; set; } 
    }   
    Public class Hourly {
         public List<string> time { get; set; }
    }   
}
