'System.Collections.Generic.List <>' in Route

Question

Attribut Ich habe eine zwei Aktionen wie unten im Restaurant Controller

[HttpPost] 
public ActionResult searchOpenRestaurants(FormCollection form) 
{ 
    TimeSpan currentTime = DateTime.Now.TimeOfDay; 
    var openRestaurants = (from t in db.Restaurants 
     where 
      t.OpeningTime == currentTime || 
      t.OpeningTime < currentTime || 
      t.ClosingTime > currentTime || 
      t.ClosingTime == currentTime 
     select new RestaurantViewModel() 
     { 
      RestId = t.Id, 
      RestaurantName = t.RestaurantName, 
      Logo = t.Logo, 
      Address = t.Address, 
      City = t.City, 
      District = t.District, 
      TimetakentoDeliver = t.TimetakentoDeliver, 
      categories = t.Restaurant_Type.Select(a => a.Category.category1).ToList(), 
     }).ToList(); 

    return View("Index", openRestaurants.ToList()); 
} 

[Route("Index/{restaurants:System.Collections.Generic.List<RestaurantViewModel>}")] 
public ActionResult Index(List<RestaurantViewModel> restaurants) 
{ 
    return View(restaurants); 
} 

und ich habe auch noch zwei Indices Aktionen wie unter

public ActionResult Index() 
     { 
      using (TheFoodyContext db = new TheFoodyContext()) 
      { 

       var model = (from p in db.Restaurants // .Includes("Addresses") here? 
          select new RestaurantViewModel() 
          { 
           RestId = p.Id, 
           RestaurantName = p.RestaurantName, 
           Logo = p.Logo, 
           Address = p.Address, 
           City = p.City, 
           District = p.District, 
           TimetakentoDeliver = p.TimetakentoDeliver, 
           categories = p.Restaurant_Type.Select(a => a.Category.category1).ToList(), 
          }); 

       return View(model.ToList()); 
       //return View(db.Restaurants.ToList()); 
      } 

     } 

     [HttpPost] 
     [Route("Index/{search:string}")] 
     // GET: Restaurant 
     public ActionResult Index(string search) 
     { 
      using (TheFoodyContext db = new TheFoodyContext()) 
      { 

       var model = (from p in db.Restaurants // .Includes("Addresses") here? 
          where p.City.StartsWith(search) || search == null 
          select new RestaurantViewModel() 
          { 
           RestId = p.Id, 
           RestaurantName = p.RestaurantName, 
           Logo = p.Logo, 
           Address = p.Address, 
           City = p.City, 
           District = p.District, 
           TimetakentoDeliver = p.TimetakentoDeliver, 
           categories = p.Restaurant_Type.Select(a => a.Category.category1).ToList(), 
          }); 

       return View(model.ToList()); 
       //return View(db.Restaurants.ToList()); 
      } 

Aber das gibt mir einen Fehler wie folgt aus:

Die Inline-Constraint-Resolver des Typs ‚DefaultInlineConstraintResolver‘ war nicht in der Lage zu lösen die folgende Inline-Einschränkung: 'System.Collections.Generic.List <RestaurantViewModel>'.

kann mir jemand einen Weg vorschlagen, dieses Problem zu erreichen ??

Answer 1

Das Problem ist in der Route:

[Route("Index/{restaurants:System.Collections.Generic.List<RestaurantViewModel>}")] 

mit Versuchen:

[Route("Index/{restaurants}")] 

Sie haben eine Liste der DefaultInlineConstraintResolver hier: DefaultInlineConstraintResolver Error in WebAPI 2
