But the Intellisence is throwing this error:

但Intellisence抛出了这个错误:

@using MvcSiteMapProvider.Web.Html

Fixed by adding this to the top of the view as said by

通过将其添加到视图的顶部来修复

The namespaces that @Steven V mentioned are automatically added to the Views\Web.config file during installation of the NuGet package.

@Steven V提到的命名空间在安装NuGet包期间会自动添加到Views \ Web.config文件中。

<configuration>
  <system.web.webPages.razor>
    <pages pageBaseType="System.Web.Mvc.WebViewPage">
      <namespaces>
        <add namespace="MvcSiteMapProvider.Web.Html" />
        <add namespace="MvcSiteMapProvider.Web.Html.Models" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>
</configuration>

However, Visual Studio intellisense requires a recompile of the project before it picks them up. There is no need to add a @using MvcSiteMapProvider.Web.Html statement to the view.

但是,Visual Studio intellisense需要在拾取项目之前重新编译项目。无需在视图中添加@using MvcSiteMapProvider.Web.Html语句。

I think you're missing a using statement. Try adding @using MvcSiteMapProvider.Web.Html to the top of the view.

我想你错过了一个使用声明。尝试将@using MvcSiteMapProvider.Web.Html添加到视图的顶部。

If you're going to use it often, think about adding the namespace to the <namespaces> section under <system.web.webPages.razor> in the Views\Web.config. That will make it available on all Razor views inside that folder without the need of an using statement on each individual view.

如果您要经常使用它,请考虑将名称空间添加到Views \ Web.config中下的部分。这将使其在该文件夹中的所有Razor视图上可用,而无需在每个视图上使用using语句。

You need to install the MvcSiteMap Provider.

您需要安装MvcSiteMap Provider。

You can do this from the Package Manger Console with the following command:

您可以使用以下命令从Package Manger Console执行此操作:

Install-Package MvcSiteMapProvider.MVC5

Then at the top of the razor add:

然后在剃刀顶部添加:

@using MvcSiteMapProvider

@using MvcSiteMapProvider.Web.Html
