C# ASP.NET MVC Basics Views Using ViewBag

Posted by Matt Slater

Move the data in the Detail.cshtml view to the ComicBooksController.cs controller's Detail action method. Use the title

I'm getting stuck on the first part of this challenge. I have my code formatted similar to that in the video, but keep getting an error that my code can't be compiled. If anyone can tell me what I'm doing wrong, it would greatly be appreciated.

Thanks.

VideoGamesController.cs 
using System.Web.Mvc;

namespace Treehouse.Controllers
{
    public class VideoGamesController : Controller
    {
        public ActionResult Detail()
        {
            var videoGame = new VideoGame()
            {
                Title = "Super Mario 64",
                Description = "Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64.",
                Characters = new Character[]
                {
                     "Mario",
                     "Princess Peach",
                     "Bowser",
                     "Toad",
                     "Yoshi"
                }
            };    

            return View(videoGame);
        }
    }
}
Detail.cshtml 
@{
    Layout = null;


}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Video Game Detail</title>
</head>
<body>
    <div>
        <h1>ViewBag.Title</h1>

        <h5>Description:</h5>
        <div>ViewBag.Description</div>

        <h5>Characters:</h5>
        <div>
            <ul>
                @foreach (var character in ViewBag.Character)
                {
                    <li>@character</li>
                }
            </ul>
        </div>
    </div>
</body>
</html>

:point_right: The challenge asks you to create ViewBag elements.

Your code is trying to construct a VideoGame object, but no such object is defined. You need to create this as ViewBag elements instead.

Also note that Characters is a simple string array. There is no Character object.

Finally, View does not get an argument.

The following codes work for both tasks.

using System.Web.Mvc;

namespace Treehouse.Controllers
{
    public class VideoGamesController : Controller
    {
        public ActionResult Detail()
        {
            ViewBag.Title = "Super Mario 64";
            ViewBag.Description = "Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64.";
            ViewBag.Characters = new string[]
            {
                "Mario",
                "Princess Peach",
                "Bowser",
                "Toad",
                "Yoshi"
            };
            return View();
        }
    }
}

@{
    Layout = null;

}

<!DOCTYPE html>

    <meta name="viewport" content="width=device-width" />
    <title>Video Game Detail</title>

        <h1>@ViewBag.Title</h1>

        <h5>Description:</h5>
        <div>@ViewBag.Description</div>

        <h5>Characters:</h5>
        <div>
            <ul>
                @foreach (var character in ViewBag.Characters)
                {
                    <li>@character</li>
                }
