ツアーとホテルの 2 つのテーブルがあります。結合を使用してクエリを実行し、ビューで結果を取得します。
下の図のように 2 つのテーブルのデータを表示するにはどうすればよいですか?
コントローラーには、次のコードがあります。
public ActionResult DetailView(string strID)
{
var id_tour = (from data1 in _db.Tours
join dataview2 in _db.TypeOfCosts on data1.ID_TourCost equals dataview2.ID_TourCost
where (data1.ID_Tour == strID) && (data1.ID_TourCost == dataview2.ID_TourCost)
select new
{
data1.TourName,
data1.ID_Tour,
data1.DepartureDay,
data1.DeparturePosition,
data1.AvailableRoom,
dataview2.AdultCost,
dataview2.ChildrenCost,
dataview2.BabyCost,
}).FirstOrDefault();
var view_tour = new DetailModels(id_tour.TourName, id_tour.ID_Tour, Convert.ToDateTime(id_tour.DepartureDay), id_tour.DeparturePosition,
Convert.ToInt32(id_tour.AvailableRoom),
Convert.ToInt32(id_tour.AdultCost), Convert.ToInt32(id_tour.ChildrenCost), Convert.ToInt32(id_tour.BabyCost));
return View(view_tour);
}
[HttpPost]
public ActionResult DetailView(DetailModels model)
{
var id_hotel = from data2 in _db.Tours
join dataview3 in _db.TourPrograms on data2.ID_Tour equals dataview3.ID_Tour
join dataview4 in _db.Programs on dataview3.ID_TourProgram equals dataview4.ID_TourProgram
join dataview5 in _db.Hotels on dataview4.ID_Hotel equals dataview5.ID_Hotel
where (data2.ID_Tour == dataview3.ID_Tour) &&
(dataview3.ID_TourProgram == dataview4.ID_TourProgram) && (dataview4.ID_Hotel == dataview5.ID_Hotel)
select new
{
dataview5.HotelName,
dataview5.HotelAddress,
dataview5.HotelPhoneNumber,
};
// chuyền dữ liệu vào như thế nào
return RedirectToAction("DetailView", "Tourpackage");
}
モデルには、次のコードがあります。
enter code here public class DetailModels
{
public string TourName { get; set; }
public string ID_Tour { get; set; }
public DateTime DepartureDay { get; set; }
public string DeparturePosition { get; set; }
public int AvailableRoom { get; set; }
public string HotelName { get; set; }
public string HotelAddress { get; set; }
public int HotelPhoneNumber { get; set; }
public int AdultCost { get; set; }
public int ChildrenCost { get; set; }
public int BabyCost { get; set; }
public DetailModels(string tourname, string idtour, DateTime dapartureday, string departureposition, int availableroom,
int adultcost, int childrencost, int babycost)
{
this.TourName = tourname; this.ID_Tour = idtour; this.DepartureDay = dapartureday; this.DeparturePosition = departureposition;
this.AvailableRoom = availableroom;
this.AdultCost = adultcost; this.ChildrenCost = childrencost; this.BabyCost = babycost;
}
みんなの助けを願って............ありがとう
