我使用 MVC 4 模板示例并发现了一个奇怪的“特色”部分。这些代码来自 _Index.cshtml：

@section featured {
    <section class="featured">
        <div class="content-wrapper">
            <hgroup class="title">
                <h1>@ViewBag.Title.</h1>
                <h2>@ViewBag.Message</h2>
            </hgroup>
            <p>

使用 Visual Studio Development Server 在 localhost 环境中运行此网站时，会呈现“特色”部分，但如果我在 IIS 上推送此网站，则不会呈现此部分。我不知道为什么？

“精选”部分是 MVC 中的隐藏功能？MVC 中是否有任何隐藏的功能？请帮助我了解有关 MVC 的更多信息。谢谢。

一个老问题，但我发现它还没有得到正确的回答。

“精选”只是一个标识网站部分的字符串，它不是关键字。Visual Studio 附带的 MVC 示例就是这样制作的，但这绝不是 MVC 中的秘密或特殊部分。它只是用来选择性地隐藏或显示这个蓝色背景的部分：

在示例中，_Layout.chtml有以下代码：

<div id="body">
    @RenderSection("featured", required: false)
    <section class="content-wrapper main-content clear-fix">
        @RenderBody()
    </section>
</div>

这将呈现以下内容：

<div id="body">
    <section class="featured">
        /* Whatever you have in your view inside the @section featured { } */
    </section>
    <section class="content-wrapper main-content clear-fix">
        /* Whatever you have in your view outside any @section */
    </section>
</div>

同样，当它读作“特色”时，您可以将其替换为您选择的任何其他词。;)

确定在 Shared/_Layout.cshtml 中：

 @RenderSection("featured ", required: false)

或者

@RenderSection("featured ", required: true)
