now in the behind code have this
public string[,] Carrito = new string[20, 13];
NoItems = Convert.ToInt32(Session["NoItems"]);//its the number of differents items
Carrito = (String[,])Session["Cart"];//its a array with all products
public void view()
{
Label1.Text = (String)Carrito[i, 1] + "/" + (String)Carrito[i, 3] + "/" + (String)Carrito[i, 4] + "/" + (String)Carrito[i, 5] + "/" + (String)Carrito[i, 6] + "/" +
(String)Carrito[i, 7] + "/" + (String)Carrito[i, 8] + "/" + (String)Carrito[i, 9] + "/" + (String)Carrito[i, 10];
Label2.Text = "$" + (String)Carrito[i, 2];
Label3.Text = "$" + (String)Carrito[i, 2];
Cantidad.Text = (String)Carrito[i, 13];
}
public void comprar(object sender, EventArgs e)
{
for (int a = 0; a < NoItems; a++)
{
}
}現在我的問題，它如何保存產品的數量，
現在我不使用一個數據庫，所有的信息，其在會議中，數據庫是在進展。
有什麼想法？對不起我的英語。
