Error concerning a sorted list not being accessible due to its protection level

[LouTheNewb]

I'm very new to c# and programming in general, so excuse my poor knowledge.
For school we have to create a blackjack game using windows form. I had to store the images of each card into a sorted list so i created a class called cardList and created a constructor which contained the the sorted list called cards. So it looks kinda like this:

public class cardList : Form1
    {
        SortedList cards = new SortedList();

        public cardList()
        {
            cards.Add(Image.FromFile("C:\\Users\\Lulu\\Documents\\cards\\club02.png"), 0);
            cards.Add(Image.FromFile("C:\\Users\\Lulu\\Documents\\cards\\club03.png"), 1);
            cards.Add(Image.FromFile("C:\\Users\\Lulu\\Documents\\cards\\club04.png"), 2);
            cards.Add(Image.FromFile("C:\\Users\\Lulu\\Documents\\cards\\club05.png"), 3);
...
// the ellipses represents the other 49 cards 
   }
}

Now I'm trying to call one of the cards to put into a picture box using a method called dealDealer in a different class called Form1:

public void dealDealer(int cardsDealt)
        {
            Random number = new Random();
            int randomCard = number.Next(1, 52);

            for (int b = 0; b < cardsDealt;)
       
                if (randomCard == cardNumber) 
                {
                    cardList c = new cardList();
                    dealer2.Image = c.cards.GetByIndex(cardNumber);
                }
                
        }

There's probably a few other errors, I'm still trying to figure this whole c# thing out. All i need right now is for some one to please explain to me why the error tells me (on the line that contains c.cards.GetByIn dex(cardNumber) ;) that cards is inaccessible due the its protection level.

Much appreciated

Please use code tags when posting code.

The default access for members is private. What you need is a public getter method that can be accessed from outside the class to return the correct image.

While you could just make the member public, it is not a recommended practice.
