Question

I was writing a question asking why @Href isn’t recognizing the path correctly.

E.g.

@helper CSS(string cssFile, string media = "screen") {
    <link href="@Href("~/content/stylesheets/" + @cssFile)" rel="stylesheet" type="text/css" media="@media" /> 
}

is throwing sereval js 404 error trying to found the resource in

• http:// localhost/content
• http:// localhost/dashboard/content

and never what I want:

• http:// localhost/MySite/content

So them I found the interesting part: @Url.Content instead of @Href works fine! Why!?

Therefore this is not the bigger problem, the issue is that in App_Code @Url doesn’t exist in the context. What I can use then.

Answer 1

MSDN is your friend. From WebPageRenderingBase.Href Method:

When overridden in a derived class, builds a URL using the specified
parameters.

Whereas from UrlHelper.Content Method:

Converts a virtual (relative) path to an application absolute path.

The tilde in your path makes it a virtual path, which apparently @Href() doesn’t understand.
