C# ASP.NET MVC Basics Views Displaying a List of Values

ASP.NET MVC Basics

I can't see where I'm going wrong, I followed the video several times...

Link: https://teamtreehouse.com/library/aspnet-mvc-basics/views/displaying-a-list-of-values

Question:

Using the Razor syntax, write the characters string array variable value to the view within the provided <ul> element.

    Use a foreach loop to render each characters string array value within its own <li> element.
    Name your loop value variable character.
    Be sure to remove the placeholder <!-- characters --> HTML comments.

My failing answer:

 @{
    Layout = null;

    var title = "Super Mario 64";
    var description = "Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64.";
    var characters = new string[]
    {
        "Mario",
        "Princess Peach",
        "Bowser",
        "Toad",
        "Yoshi"
    };
}

<!DOCTYPE html>

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

        <h5>Description:</h5>
        <div>@description</div>
        @if (characters.Length > 0)
    {
                <h5>Characters:</h5>
        <div>
            <ul>
        @foreach(var character in characters)
        {
        <li>@characters</li>

        }

            </ul>
        </div>
    }

    </div>
</body>
</html>

This is just one variation of my attempts.

Detail.cshtml
@{
    Layout = null;

    var title = "Super Mario 64";
    var description = "Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64.";
    var characters = new string[]
    {
        "Mario",
        "Princess Peach",
        "Bowser",
        "Toad",
        "Yoshi"
    };
}

<!DOCTYPE html>

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

        <h5>Description:</h5>
        <div>@description</div>
        @if (characters.Length > 0)
    {
                <h5>Characters:</h5>
        <div>
            <ul>
        @foreach(var character in characters)
        {
        <li>@characters</li>

        }

            </ul>
        </div>
    }

    </div>
</body>
</html>

:mailbox_with_mail: Hi, I got your request to answer.

It looks like you have the wrong name .. or maybe just a typo.

Your loop is correct, but when you render the item within the <li> tags, you call it "characters" (the whole array) instead of "character" (the individual item).

Just remove that "s" and you'll pass!

I did, I get the following error:

Bummer! Did you remove any of the provided markup?

Oh, it looks like you did too much. You should only replace the "<!-- characters -->" line with the loop that generates the <li>'s. Don't make any other changes (like adding that "@if..." line).
