Using Url.Content in ASP.net MVC 2.0

I have seen many examples using Url.Content to reference javascript, a MasterPages form in MVC 2.

<script src="<%: Url.Content("~/Scripts/jquery-1.4.1.min.js") %>" type="text/javascript"></script>

But at runtime, I had a crash,

Compilation Error Description: An error occurred while compiling the resource required to service this request. Review the following specific error data and modify the source code accordingly.

Compiler Error Message: CS0103: The name "Url" does not exist in the current context.

I have not found where the Url namespace is declared, should additional assemblies be used?

VS2010, IIS 7, ASP.net MVC 2.0

Make sure your main page inherits System.Web.Mvc.ViewMasterPage

try adding the following extension method and see if it gets you further

 public static partial class HtmlHelperExtensions { public static string Script(this HtmlHelper html, string path) { var filePath = VirtualPathUtility.ToAbsolute(path); HttpContextBase context = html.ViewContext.HttpContext; // don't add the file if it already there if (context.Items.Contains(filePath)) return ""; return "<script type=\"text/javascript\" src=\"" + filePath + "\"></script>"; } }

using:

 <%=Html.Script("~/Scripts/jquery-1.4.2.min.js")%>

I know that it will not answer your question directly, but will allow you to move fwd ...

Editing has been removed because single quotes are treated as a character literal, therefore causing "too many characters in a literal" error. The most likely reason is still a typo, IMHO.

ORIGINAL MAIL (UrlHelper class still stands):

Url.Content (): Url here is a helper method, a bit like the Html or Ajax helpers.

In the code, I believe its class is:

System.Web.Mvc.UrlHelper

That is, the namespace is System.Web.Mvc.

So it’s very strange that you cannot just use it if, that is, you really use the specification described in detail above.
