asp.net-mvc-3 - Razor 模板变量范围

Question

我在共享布局 _Layout.cshtml 中定义的变量是否在 View 页面的范围内？

_Layout.cshtml 变量:

@{
    ViewBag.url = "http://www.website.com/site/";
}

Index.cshtml:

<a class="continue" href="@ViewBag.url/our-vision/">Continue</a>

输出:/our-vision/

您可以尝试回答这个问题:How do I set ViewBag properties on _ViewStart.cshtml?

设置(注意:代码是针对_ViewStart，不是针对_Layout)

@{
    PageData["message"] = "Hello";
}

获取

<h2>@PageData["message"]</h2>
