会话不保存值

Question

我有多个会话变量，它们都不接受其他变量赋予它们的任何值。我试图调试，什么都没发现。这是我正在使用的功能......

    public void logIn(object sender, EventArgs e) //triggers when login button is clicked
    {

        db_connection(); //connects to database using above function

        string emailAddress = email.Text.ToString();
        string passwordR = password.Text.ToString(); //email and password are converted to variables

        DataTable table = new DataTable();

        MySqlCommand select = new MySqlCommand("SELECT personID, address_addressID from person WHERE email='" + emailAddress + "' and password = '" + passwordR + "'", connect); //brings back the person ID if user details are correct            
        using (MySqlDataAdapter adapter = new MySqlDataAdapter(select))
        {
            adapter.Fill(table);

            string sessionVar = table.Rows[0]["personID"].ToString();
            Session["personID"] ="";
            Session["personID"] = sessionVar;

            int sessionVarAddress = Int32.Parse(table.Rows[0]["address_addressID"].ToString());
            Session["address_addressId"] = sessionVarAddress;


            if (table.Rows.Count != 0)
            {

                if (Session["personID"] != null) //if the person ID is present do this following statement
                {
                    hideDiv.Visible = false;
                }

                Response.Redirect("myAccount.aspx"); // if user logs in successfully redirect to my account pag

            }

            else
            {
                Response.Redirect("index.aspx"); //if login fails, home page is returned
            }

            connect.Close();
        }
        }
