Following is a working program to add new articles. The only thing I want is to check if there is any way to write it in a better way, or if the architecture is good as it is.Maybe I did not have to user a new class ListOfProducts I could easily create a list in the Articles class and add items directly in the BuyItem() method, but I just wanted to try inheritance and work on my skills.Any other recommendation?class Program{    static void Main(string[] args)    {        Guid id;         id = Guid.NewGuid();        Articles article = new Articles(id, This is a new article, 3, 20.2);        article.BuyItem(article);        Console.WriteLine(article);        Console.ReadLine();    }}public class Articles : ListOfProducts{    private Guid Id { get; set; }    private string Description { get; set; }    private int Quantity { get; set; }    private double Price { get; set; }    public Articles(Guid id, string description, int quantity, double price)    {        this.Id = id;        this.Description = description;        //should check if the quatity > 0        this.Quantity = quantity;        this.Price = price;    }    // add item    public void BuyItem(Articles article)    {        AddNewArticle(this);    }    //Sell item    public void SellItem(Articles article)    {        RemoveNewArticle(this);    }    public override string ToString()    {        return Article: + Id+ is Added.;    }}public class ListOfProducts{    private List<Articles> ListOfArticles = new List<Articles>();    public void AddNewArticle(Articles art)    {        ListOfArticles.Add(art);            }    public void RemoveNewArticle(Articles art)    {        ListOfArticles.Remove(art);    }}
