Question

你好，我需要帮助我正在创建我的第一个ASP MVC网页。我创建了一个与数据库连接的登录和注册页面。

我想从登录到Bookings表的客户那里传递CustomerId 这样它只显示与该客户有关的预订。 Bookings表具有CustomerId作为外键。到目前为止，这是我所做的。

public class BookingController : Controller
{
    // GET: Booking
    public ActionResult Index(int customerId)
    {

        TravelExpertsEntities bookingdb = new TravelExpertsEntities();
        List<Booking> bookings = bookingdb.Bookings.Where(book => 
book.CustomerId == customerId).ToList();
        return View(bookings);
    }
}
}

//This is from login Controller 

 public ActionResult Login(Customer reg)
    {
        if (ModelState.IsValid)
        {
            var details = (from userlist in db.Customers
                           where userlist.UserName == reg.UserName && 
      userlist.Password == reg.Password
                           select new
                           {
                               userlist.CustomerId,
                               userlist.UserName
                           }).ToList();
            if (details.FirstOrDefault() != null)
            {
                Session["CustomerId"] = 
      details.FirstOrDefault().CustomerId;
                Session["Username"] = details.FirstOrDefault().UserName;
                return RedirectToAction("Index", "Booking");
            }
        }
        else
        {
            ModelState.AddModelError("", "Invalid UserName or Password");
        }
        return View(reg);
    }

我能够提取所有预订，但我想与已登录的客户进行过滤。

如下所示替换您的RedirectToAction，以将customerId作为参数传递

var CustomerIdparam=details.FirstOrDefault().CustomerId;
RedirectToAction("Index", "Booking", new{customerId=CustomerIdparam});

如何从登录页面传递值
