Casting a Session variable as an array

I have a list that is converted to an array then put into a session so in another page i would access to that array but when I'm trying to unbox it, it would not return a correct value

//codes from page one :
List<string> seatNum = new List<string>();
string[] seatnumArray = new string[ordered]; //Ordered is a defined int variable
seatnumArray = seatNum.ToArray();

//codes from page two :
if (Session["SeatNum"] != null){
    lblseatname.Text = Session["SeatNum"].ToString();
}

//Output view :
System.String[]

You need to convert the Session object back to a List

List<string> seatNumFromSession = Session["SeatNum"] as List<string>;

Then you can use it again as you would any other List.

lblseatname.Text = seatNumFromSession[0];
