Public Array with a class not showing in Inspcetor

I have a class ItemClass and I’m trying to create a public ItemClass but I can’t see anything in the inspector. Is there something missing? Here is the ItemClass followed by the script with the array:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ItemClass {

    private string itemName;
    private string itemDesc;

    private int cost;
    private int dungeonUnlock;

    private int attackInc;
    private int defenseInc;
    private int vitInc;

    private int healingAmount;
    private string loadScene;

    public enum ItemType
    {
        Accessory,
        Armor,
        Weapon,
        Potion,
        Support
    }
    private ItemType itemTypes;


    public string ItemName { get; set; }
    public string ItemDesc { get; set; }

    public int Cost { get; set; }
    public int DungeonUnlock { get; set; }

    public int AttackInc { get; set; }
    public int DefenseInc { get; set; }
    public int VitInce { get; set; }

    public int HealingAmount { get; set; }
    public string LoadScene { get; set; }


    public ItemType ItemTypes { get; set; }

}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class ShopContents : MonoBehaviour {

    public ItemClass[] allItems;
    public GameObject[] gameObjects;
    public List<ItemClass> availableItems;

    void Start()
    {
        availableItems = new List<ItemClass>();

        DungeonCheck();
    }

    void DungeonCheck()
    {
        availableItems.Clear();
        foreach (ItemClass item in allItems)
        {
            if (PlayerStatManager.dungeonsBeaten >= item.DungeonUnlock)
            {
                availableItems.Add(item);
            }
        }
    }

}

[System.Serializable]
public class ItemClass {…

And change the fields to public OR mark them with [SerializeField] to to see them on inspector
(properties are not visible/seriazable on inspector)

As for the shopContents class you don’t need to mark it as serializable.
