세부 정보를 표시하는 방법 선택한 차량의 모습?

Question

ASP.NET MVC 5의 새로운 기능입니다.

차고 세부 정보를 생성했습니다.

@model TestApp.Models.Garage 

@{ 
    ViewBag.Title = "Details"; 
} 

<h2>Details</h2> 

<div> 
    <h4>Category</h4> 
    <hr /> 
    <dl class="dl-horizontal"> 
     <dt> 
      @Html.DisplayNameFor(model => model.Name) 
     </dt> 

     <dd> 
      @Html.DisplayFor(model => model.Name) 
     </dd> 

     <dt> 
      @Html.DisplayNameFor(model => model.Description) 
     </dt> 

     <dd> 
      @Html.DisplayFor(model => model.Description) 
     </dd> 

    </dl> 

    <hr /> 

    <div>Cars of garage</div> 

    <div> 
     @foreach (var item in Model.Cars) 
     { 
      <li>@Html.ActionLink(@item.Name, "Details", "Cars")</li> // should be correct code line 
     } 
    </div> 

    <hr /> 

</div> 
<p> 
    @Html.ActionLink("Edit", "Edit", new { id = Model.GarageID }) | 
    @Html.ActionLink("Back to List", "Index") | 
    @Html.ActionLink("Add Car", "Create", "Cars") 
</p> 

차고의 차 목록을 보여주고 싶습니다. 차를 몇 대 클릭하고이 차의 세부 사항으로 이동할 수 있습니다. 그러나 @ Html.ActionLink (@ item.Name, "Details", "Cars") 메소드의 일반 인터페이스를 찾을 수 없습니다.

public class CarsController : Controller 
{ 
    private TestDBContext db = new TestDBContext(); 

    public async Task<ActionResult> Index() 
    { 
     var cars = db.Cars.Include(p => p.Category); 
     return View(await cars.ToListAsync()); 
    } 

    public async Task<ActionResult> Details(int? id) 
    { 
     if (id == null) 
     { 
      return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
     } 
     Cars car = await db.Cars.FindAsync(id); 
     if (car == null) 
     { 
      return HttpNotFound(); 
     } 
     return View(cars); 
    } 

    public ActionResult Create() 
    { 
     ViewBag.GarageID = new SelectList(db.Garages, "GarageID", "Name"); 
     return View(); 
    } 

    [HttpPost] 
    [ValidateAntiForgeryToken] 
    public async Task<ActionResult> Create([Bind(Include="CarID,Name,Description, GarageID")] Car car) 
    { 
     if (ModelState.IsValid) 
     { 
      db.Cars.Add(car); 
      await db.SaveChangesAsync(); 
      return RedirectToAction("Index"); 
     } 

     ViewBag.GarageID = new SelectList(db.Garages, "GarageID", "Name", car.GarageID); 
     return View(car); 
    } 

    public async Task<ActionResult> Edit(int? id) 
    {

     { 
      return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
     } 
     Car car = await db.Cars.FindAsync(id); 
     if (car == null) 
     { 
      return HttpNotFound(); 
     } 
     ViewBag.GarageID = new SelectList(db.Garages, "GarageID", "Name", car.GarageID); 
     return View(car); 
    } 

    [HttpPost] 
    [ValidateAntiForgeryToken] 
    public async Task<ActionResult> Edit([Bind(Include="CarID,Name,Description,GarageID")] Car car) 
    { 
     if (ModelState.IsValid) 
     { 
      db.Entry(car).State = EntityState.Modified; 
      await db.SaveChangesAsync(); 
      return RedirectToAction("Index"); 
     } 
     ViewBag.GarageID = new SelectList(db.Garages, "GarageID", "Name", car.GarageID); 
     return View(car); 
    } 

    public async Task<ActionResult> Delete(int? id) 
    { 
     if (id == null) 
     { 
      return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
     } 
     Car car = await db.Cars.FindAsync(id); 
     if (car == null) 
     { 
      return HttpNotFound(); 
     } 
     return View(car); 
    } 

    [HttpPost, ActionName("Delete")] 
    [ValidateAntiForgeryToken] 
    public async Task<ActionResult> DeleteConfirmed(int id) 
    { 
     Cars car = await db.Cars.FindAsync(id); 
     db.Cars.Remove(car); 
     await db.SaveChangesAsync(); 
     return RedirectToAction("Index"); 
    } 
} 

Answer 1

당신은 CarsController 지금처럼 세부 방법을 탐색 알 수 있도록 귀하의 ActionLink에 널 (NULL) 매개 변수를 추가해야합니다

@Html.ActionLink(item.Name, "Details", "Cars", new { id = item.Id }, null)
