使用LinQ從兩個表（視圖和列表）獲取數據並返回到一個視圖（代碼MVC-C＃）

Question

我有兩個表：旅遊和酒店我想執行連接查詢並在視圖中獲取結果。

如何查看兩個表中的數據，如下圖所示？

在控制器

我有這樣的代碼：

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"); 
    } 

示範我有這樣的代碼：

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; 
    } 

希望對大家的幫助.... ........謝謝

當您使用MVC我強烈重新建議您使用實體框架。如果你從來沒有使用它檢查了這一點：http://www.pluralsight-training.net/microsoft/Courses/TableOfContents?courseName=aspdotnet-mvc3-intro - 非常好的視頻教程。 我認爲Tour - Hotel關係是典型的多對多關係。映射EF類旅遊將有財產Hotels，反之亦然。如果您傳遞例如Tour查看@Model.Hotels給你收集相關酒店。並BTW做一些重構代碼，請:)
