c# - 如何显示连接到数据库的 LINQ 表中的数据？

Question

我正在尝试制作一个预订系统，我可以在其中从 LINQ 中的列表中获取数据，并将其显示在一系列文本框中，但我遇到了问题，因为当我运行程序时它只显示数字 1。

这是我的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;

namespace BookingCustomers
{
    public partial class BookingGuests : System.Web.UI.Page
    {
        private HotelConferenceEntities datacontext = new HotelConferenceEntities();

        private void Page_Load(object sender, EventArgs e)
        {
            if (Page.IsPostBack)
            {
                    int id = int.Parse(BookID.Text.ToString());
                    tblBooking booking = datacontext.tblBookings.SingleOrDefault(x => x.BookingID == id);

                    tblVenue venue = datacontext.tblVenues.SingleOrDefault(x => x.VenueID == booking.Venue);

                    List<tblCustomer> customers = new List<tblCustomer>();
                    List<tblBookingGuest> guests = booking.tblBookingGuests.ToList();

                    foreach (tblBookingGuest guest in guests)
                    {
                        tblCustomer newcust = datacontext.tblCustomers.SingleOrDefault(x=>x.CustomerID == guest.CustomerID);
                        customers.Add(newcust);
                    }

                    int count = customers.Count;

                    //string table=string.Join(",",customers);

                    int [] displayer={customers.Count};
                    int max=(displayer.Max());
                    CustFirstName.Text =displayer.Where(p=> p== max).Count().ToString();
