我傳遞數據的2個表成一個單一的看法，但我得到一個錯誤

Question

我得到一個錯誤：

The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery`1[jetjourneys.ViewModel.ItineraryPage]', but this dictionary requires a model item of type 'jetjourneys.ViewModel.ItineraryPage

代碼：

public class ItineraryPage 
{ 
    public PackageGallery Package { get; set; } 
    public tblItinerary Itinerarydetail { get; set; } 
} 

public ActionResult ItineraryPackage(int id) 
{ 
     using (travelAndTourismEntities objentity = new travelAndTourismEntities()) 
     { 
      var query = (from x in objentity.tblItineraries 
         from y in objentity.PackageGalleries 
         where x.Imageid == id && y.Imageid == id 
         select new ItineraryPage { Package = y, Itinerarydetail = x }); 
      return View(query); 
     } 
} 

這是我的控制器，請幫助我在哪裏，我犯了一個錯誤

Answer 1

你還是返回IQueryable對象，而不是實際的結果，這應該工作

FirstOrDefault()

public ActionResult ItineraryPackage(int id) 
{ 
     using (travelAndTourismEntities objentity = new travelAndTourismEntities()) 
     { 
      var query = (from x in objentity.tblItineraries 
         from y in objentity.PackageGalleries 
         where x.Imageid == id && y.Imageid == id 
         select new ItineraryPage { Package = y, Itinerarydetail = x }); 

      return View(query.FirstOrDefault()); //Update here 
     } 
}
