Suggestions on storing shopping cart info

[Cirene]

I am writing a shopping cart app in asp.net.

So far I created 2 classes, 1 for customer_info (name, address, email), 1
for product_info (prodname, price, description).

As the shopper adds things to the cart and navigates throught the site to
shop more, should I store this info in a session var? What is the typical
way? Should I create another class for cart and store an array of
product_info to keep track of what's in the cart, etc...?

What do you recommend?

Thanks

That would work. Alternatively, if you want the customer to be able to save
the cart and come back to it later, you should save it to a database...

to keep track of what's in the cart, etc...?

That's what I do, though I tend to use a generic e.g. Dictionary<int, int>
to store the ID of the purchased product along with the number of items
purchased...

Would using a generic list (of these objects) be the best way to handle this
in your opinion? Store that to a session var?

No it wouldn't, otherwise that's what I'd be doing. I've never found any
need to persist anything other than the ID of the item bought together with
the number of items purchased.

But to perisist it using a session var doesn't using a List allow you to
easily access, add and remove items in the cart? Or should I just use an
arraylist of the cart items?

I was just looking at this and it seemed like a good idea...

By the way i'm not sure what "top-posting" is. I just hit "Reply to Group"
in Outlook Express. :)
