I have 3 different lists in "UrnikPrevozov" class, I want to populate them with data from JSON for each list, but I am not quite sure how to correctly do it. Any help would be greatly appreciated.

This is my json:

{
  "UrnikAvtobus": [
    {
      "Linija": 34,
      "Trajanje": "01:15:00",
      "Voznik": "Rojko Mulic",
      "Vstop": "Velenje",
      "Izstop": "Maribor",
      "CenaVozovnice": 2.90
    }
  ],
  
  "UrnikAvto": [
    {
      "Znamka": "MERCEDES",
      "Registerska": "LJ 455-AA",
      "Vinjeta": 0,
      "Vstop": "Maribor",
      "Izstop": "Velenje",
      "CenaVozovnice": 5.40
    }
  ],

  "UrnikKombi": [
    {
      "Sedezi": 8,
      "Odhod": "2022-12-12T09:15:00",
      "Prihod": "2022-12-12T12:31:00",
      "Vstop": "Maribor",
      "Izstop": "Ljubljana",
      "CenaVozovnice": 3.70
    }
  ]
}

My UrnikPrevozov class where I want to bind the data to the lists:

public class UrnikPrevozov : Prevoz
{
    public List<AvtobusniPrevoz> UrnikBus { get; set; }

    public List<AvtoPrevoz> UrnikAvto { get; set; }

    public List<KombiPrevoz> UrnikKombi { get; set; }

}

This is how I read my json:

public void LoadJson()
{
    string data = File.ReadAllText("./Data/data.json");

    var urniki = JsonConvert.DeserializeObject<UrnikPrevozov>(data);
}

AvtoPrevoz class

  public class AvtoPrevoz : Prevoz
  {

    public string Znamka { get; set; }
    public string Registerska { get; set; }
    public Vinjeta Vinjeta { get; set; }


    public AvtoPrevoz(string znamka, string registerska, Vinjeta vinjeta, string vstop, string izstop, double cenaVozovnice) : base(vstop, izstop, cenaVozovnice)
    {
      Znamka = znamka;
      Registerska = registerska;
      Vinjeta = vinjeta;
    }
}

Prevoz class

public abstract class Prevoz
{
    public string Vstop { get; set; }
    public string Izstop { get; set; }
    public double CenaVozovnice { get; set; }

    protected Prevoz(string vstop, string izstop, double cenaVozovnice)
    {
        Vstop = vstop;
        Izstop = izstop;
        CenaVozovnice = cenaVozovnice;
    }
}

Method call in main:

UrnikPrevozov urnik = new UrnikPrevozov();
urnik.LoadJson();

CodePudding user response：

Your UrnikPrevozov class should not be inheriting Prevoz since it does not need the fields Prevoz has. And you would need parameterless constructors for all your classes.

Update: Full working code:

using System;
using System.Collections.Generic;
using Newtonsoft.Json;
using System.Linq;
using System.IO;

public class Program
{
  public static void Main()
  {
    string json = File.ReadAllText("./Data/data.json");
    
    UrnikPrevozov urnik = JsonConvert.DeserializeObject<UrnikPrevozov>(json);

    Console.WriteLine(urnik.UrnikAvto.First().Vstop);
  }
}

public class AvtobusniPrevoz : Prevoz
{
  public int Linija { get; set; }
  public string Trajanje { get; set; }
  public string Voznik { get; set; }
}

public class AvtoPrevoz : Prevoz
{
  public string Znamka { get; set; }
  public string Registerska { get; set; }
  public int Vinjeta { get; set; }
}

public class KombiPrevoz : Prevoz
{
  public int Sedezi { get; set; }
  public DateTime Odhod { get; set; }
  public DateTime Prihod { get; set; }
}

public abstract class Prevoz
{
  public string Vstop { get; set; }
  public string Izstop { get; set; }
  public double CenaVozovnice { get; set; }
}

public class UrnikPrevozov
{
  public List<AvtobusniPrevoz> UrnikBus { get; set; }

  public List<AvtoPrevoz> UrnikAvto { get; set; }

  public List<KombiPrevoz> UrnikKombi { get; set; }
}

CodePudding user response：

you have a typo in UrnikPrevozov class , replace UrnikBus by UrnikAvtobus, also you don't need any base class here

public class UrnikPrevozov
{
    public List<AvtobusniPrevoz> UrnikAvtobus { get; set; }

    public List<AvtoPrevoz> UrnikAvto { get; set; }

    public List<KombiPrevoz> UrnikKombi { get; set; }
}
