Hello,

What I would like to do is store shopping cart items into session and store them in session array as such:

 
Session["cart"]
[0] => "1234"         - ItemID
          => "1"           - Qty
          => "10.00"    - Price
[1] => "1168"
          => "2"
          => "20.00"

not sure if you're looking for a .NET solution or classic asp solution (since that's what you put the question in). I'm assuming .NET, so try this below:

string[,] myArray = new string[,] { { "1234", "1", "10.00" }, { "1168", "2", "20.00" };
Session("cart") = myArray;

Just as easy as storing the array in the session, you can store in a cookie.  One of the problems with sessions is if the worker process over loads for some reason, the session restarts.  I have run into that before, it is not common, but does happen.  

On a slight tangent, it is best for your cart to store just the item_id and qty.  The price should be by a database look up and especially when submitting the final payment form.  Only submit item_id and qty and let the back end figure out the correct price, discount etc so you don't get spoofed.

thanks Big monty,

Additionally, To retrieve from session:

var cartItems = (string[,])HttpContext.Current.Session["cart"];

Open in new window


To Count rows or columns:

int rows = cartItems .GetLength(0); 
int cols = cartItems .GetLength(1);
