Issues Deserializing JSON

I'm trying to use newtonsoft.json to deserialize a json string returned from White Pages Pro api. Everything worked perfectly and deserialized flawlessly UNTIL i got to is_commercial. Everything past there is where I run into issues with. The errors I'm encountering are as follows:

WhitePagesTool.jsonPersonComplex' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'WhitePagesTool.jsonPersonComplex' could be found (are you missing a using directive or an assembly reference?)

All Errors Thrown Below

Also throws the same error for all the following: firstname, middlename, lastname, age_range, gender, street_line_1, street_line_2, city, postal_code, state_code, country_code, latitude, longitude, accuracy, and associated_people

This is my Deserialization Class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Newtonsoft.Json;

namespace WhitePagesTool
{
    class jsonPersonComplex
    {
        public string id { get; set; }
        public string phone_number { get; set; }
        public bool is_valid { get; set; }
        public string line_type { get; set; }
        public string carrier { get; set; }
        public bool is_prepaid { get; set; }
        public bool is_commercial { get; set; }
        public List<BelongsTo> belongs_to { get; set; }


        public class BelongsTo
        {
            public string name { get; set; }
            public string firstname { get; set; }
            public string middlename { get; set; }
            public string lastname { get; set; }
            public string age_range { get; set; }
            public string gender { get; set; }
            public string type { get; set; }

        }
        public class CurrentAddress
        {
            public string street_line_1 { get; set; }
            public object street_line_2 { get; set; }
            public string city { get; set; }
            public string postal_code { get; set; }
            public string state_code { get; set; }
            public string country_code { get; set; }
            public LatLong lat_long { get; set; }
        }

        public class LatLong
        {
            public double latitude { get; set; }
            public double longitude { get; set; }
            public string accuracy { get; set; }
        }

        public class AssociatedPeople
        {
            public string name { get; set; }
            public string firstname { get; set; }
            public string middlename { get; set; }
            public string lastname { get; set; }
            public string relation { get; set; }
        }

    }

}

    You 'name' property isn't in the 'jsonPersonComplex' class but in the 'BelongsTo' class.

    debugOutput("Name:  " + jPerson.name);  //should be
    debugOutput("Name:  " + jPerson.belongs_to().FirstOrDefault()?.name); //sorta like this for example.
    

    Also your naming convention is off. Newtonsoft will automatically uppercase the names for you, although the lowercase should work I suggest making the c# version with c# standards. Newtonsoft will convert following standards so it's ok.

    I tried this and it works

    namespace WhitePagesTool
    {
        class JsonPersonComplex
        {
            public string Id { get; set; }
            public string Phone_number { get; set; }
            public bool Is_valid { get; set; }
            public string Line_type { get; set; }
            public string Carrier { get; set; }
            public bool Is_prepaid { get; set; }
            public bool Is_commercial { get; set; }
            public List<BelongsTo> Belongs_to { get; set; }
        }
    
        public class BelongsTo
        {
            public string Name { get; set; }
            public string Firstname { get; set; }
            public string Middlename { get; set; }
            public string Lastname { get; set; }
            public string Age_range { get; set; }
            public string Gender { get; set; }
            public string Type { get; set; }
    
        }
    
        public class CurrentAddress
        {
            public string Street_line_1 { get; set; }
            public object Street_line_2 { get; set; }
            public string City { get; set; }
            public string Postal_code { get; set; }
            public string State_code { get; set; }
            public string Country_code { get; set; }
            public LatLong Lat_long { get; set; }
        }
    
        public class LatLong
        {
            public double Latitude { get; set; }
            public double Longitude { get; set; }
            public string Accuracy { get; set; }
        }
    
        public class AssociatedPeople
        {
            public string Name { get; set; }
            public string Firstname { get; set; }
            public string Middlename { get; set; }
            public string Lastname { get; set; }
            public string Relation { get; set; }
        }
    }
    

    And then in the logic...

    var jPerson = JsonConvert.DeserializeObject<JsonPersonComplex>(jsonString);  
    
    debugOutput("Phone ID: " + jPerson.Id.ToString());
    debugOutput("Phone Number: " + jPerson.Phone_number.ToString());
    debugOutput("Valid Number: " + jPerson.Is_valid);
    debugOutput("Line Type: " + jPerson.Line_type);
    debugOutput("Carrier: " + jPerson.Carrier);
    debugOutput("Prepaid: " + jPerson.Is_prepaid);
    debugOutput("Commercial: " + jPerson.Is_commercial);
    
    debugOutput("Name:  " + jPerson.Belongs_to.FirstOrDefault().Name); //and so on
