Challenge Task 2 of 2

Update the Detail.cshtml view to use the ViewBag data. Remove the title, description, and characters variables. Replace the title, description, and characters references with the respective ViewBag properties.

VideoGamesController.cs 
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();
        }
    }
}
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.Characters)
                {
                    <li>@character</li>
                }
            </ul>
        </div>
    </div>

Bummer! Did you replace the 'title' variable reference with the 'ViewBag.Title' property?

You're really close, but I see two issues:

  • C# is case sensitive, and you wrote "Viewbag" (with a lower-case "b") instead of "ViewBag" (capital "B")
  • on the foreach line, you don't need a second "@" symbol, the first one affects the entire line

OMG, I can't believe I missed that, I was trying to figure out how this was wrong, I tried not adding the second @ previously, but it didnt work due to my lowercase "b"...Thank you for pointing this out :)

<h1>@Viewbag.Title</h1>

Check your capitalization, change it to ViewBag.Title.

As well you have another mistake here: @foreach (var character in @ViewBag.Characters). Before ViewBag.Chaacters you don't need @, because you have @ before foreach

That was the second of the two issues I pointed out 3 years ago. :wink:
