Using XmlTextReader to read a file on the same server via http

Question

I'm sure there's something blindingly obvious I'm missing here.

I have an ASP.NET MVC2 app with an XML doc at /content/mydoc.xml. I'm trying to load it using XmlTextReader:

XmlTextReader reader = new XmlTextReader("/content/mydoc.xml");

Stepping through, I can see that this is being resolved to file:///C:/content/mydoc.xml

I know I can use Server.MapPath() to get the file path but that seems rather hackish given that the XML doc is available via http.

Is there a way to get XmlTextReader to properly resolve the URL?

How about

XmlTextReader reader = 
    new XmlTextReader(Url.GenerateContentUrl("~/content/mydoc.xml"));

Of course, you'll need an UrlHelper instance to hand to accomplish this (available as the Url field in view and controller).

EDIT

If I know where the file lives I'd prefer to go for it as a file, not with the overhead of HTTP. As such MapPath seems like a good choice here.

Thanks. However, this just seems to resolve ~/content/mydoc.xml back to /content/mydoc.xml. I can use the answer from stackoverflow.com/questions/1288046/… to get the base URL and construct the full URL, but that seems rather convoluted for something that seems like it should be simple

+1 for accessing the file via the file system rather than HTTP, unless you have a specific reason to do it.

Cheers guys - it does indeed make more sense.
