Need to copy items from one listbox to another listbox using a session variable

Page 1: (sending listbox items into a list and saving the list as a session variable)

List<string> list = new List<string>();
foreach(ListItem item in ListBox1.Items)
{
    list.Add(item.ToString());
}
Session["temp"] = list;

Page 2: (copying the session variable into a list and assigning the list to a listbox in this page)

List<string> list = new List<string>();
list = (List<string>)Session["JobRole"];
foreach (ListItem item in list)
{
    ListBox2.Items.Add(item.ToString());
}

On doing so, this is the error i m getting : Cannot convert type 'string' to 'System.Web.UI.WebControls.ListItem'

can anyone pls help me with this ??

Thanks

That's because you have defined list as List. If you simply want to add the string value into the listbox you can do:

List<string> list = new List<string>();
        list = (List<string>)Session["JobRole"];
        foreach (string item in list)
        {
            ListBox2.Items.Add(item);
        }

Also you should check that Session["JobRole"] is not null.

Don't you mean

    foreach (string item in list)
    {
        ListBox2.Items.Add(item);
    }

... list is a list of strings after all.
