Map the physical file path in asp.net mvc

Question

I am trying to read an XSLT file from disk in my ASP.Net MVC controller. What I am doing is the following:

string filepath = HttpContext.Request.PhysicalApplicat         


        

Answer 1

I would have the site root path injected into the controller constructor by the DI framework:

public class HomeController: Controller
{
    private readonly string _siteRoot;
    public HomeController(string siteRoot)
    {
        _siteRoot = siteRoot;
    }

    public ActionResult Index()
    {
        string filePath = Path.Combine(_siteRoot, @"Content\Xsl\pubmed.xslt");
        return File(filePath, "text/xml");
    }
}

As far as the site root path is concerned it can be expressed with the HostingEnvironment.ApplicationPhysicalPath static property.
