How to get multiple column values from DB in session variables on login

protected void Page_Load(object sender, EventArgs e)

            MasterDCDataContext db = new MasterDCDataContext();
            var q = db.MOptions;
            lvAboutus.DataSource = q;
            lvAboutus.DataBind();

            lvAddress.DataSource = q;
            lvAddress.DataBind();

            var p = db.Posts;
            lvFooterNews.DataSource = p.OrderByDescending(c => c.PoID).Take(8);
            lvFooterNews.DataBind();

            var t = Session["LoginID"];
            mvLogin.ActiveViewIndex = Convert.ToInt32(t);
            int role = Convert.ToInt32(t);

            var m = Session["UserID"];
            int Us = Convert.ToInt32(m);

                string strConnection = "Data Source =Ali-HP;Database=EzBuy;Integrated Security=yes";
                using (SqlConnection Connection = new SqlConnection(strConnection))

                    SqlCommand Command = new SqlCommand(strQuery,Connection);
                    Command.Connection.Open();
                    SqlDataReader rdr = Command.ExecuteReader();
                    rdr.Read();
                    switch(role)
                    {
