C# ArrayList Help - ASP.NET

[kinkay716]

Hello -

Im looking for some clarification on ArrayLists for a project I'm working on. It is basically a program which allows you to create a custom deck of cards. There is a listbox of available cards, the user selects a card and clicks add, which invokes a method to add to the arraylist.

My AddCard onclick events looks something like the following:

protected void add_Click(objec t sender, EventArgs e)
{


CustomDeck newCustomDeck;
newCustomDeck = (CustomDeck)Ses sion["CurrentDec k"];


Card newCard = new Card();

newCard.Name = cardListBox.Sel ectedItem.Text;
newCard.CardID = cardListBox.Sel ectedItem.Value ;

newCustomDeck.A ddCard(newCard) ;

Session["CurrentDec k"] = newCustomDeck;

}

- My AddCard Method looks like:

//_newDeck is the ArrayList which is part of my CustomDeck domain class.
public bool AddCard(Card card)
{

_newDeck.Add(ca rd);
return true;

}

- So by my logic, when I instantiate a new card and add it into the arraylist, the arraylist will be full of different 'card' instances. How would I go about implementing the removeCard method? When i pass a card object into the arraylist, what is the handle of the card object? When I implement the removeCard method, Ill need some sort of handle to the proper card I want to remove...

if i do the following:
public bool RemoveCard(Card card)
{

_newDeck.Add(ca rd);
return true;

}

How does the arraylist know which card I am referring to?

Any help would be great!
Thanks.
