Solution 1

The listbox maintains a collection of strings, while the label contains just one string.
If you wish to set the label text with the result of the concatenation of the listbox item strings then:

Build the 'concatenated string' by iterating over the listbox items.
Assign the concatenated string to your label text.

In first form use Session
ArrayList al = new ArrayList();
for (int i = 0; i < ListBox1.Items.Count; i++)
{
// if (ListBox1.Items[i].Selected == true)
// {
al.Add(ListBox1.Items[i].Value);
// }
}
Session["ListBoxItem"] = al;

and second form

lblResult.Text = "";

string[] products = (string[])Session["ListBoxItem"];

for (int i = 0; i < products.length; ++i)
{

lblResult.Text += products[i] + ",";

}
