Nancy: is there a Server.MapPath("~/") equivalent?

Question

I can't seem to find an equivalent in Nancy for System.Web.HttpContext.Current.Server.MapPath() in the Nancy framework.

I just want to load a textfile relative to the application service.

I see this in the assembly

using Nancy;
using System;

namespace Nancy.Hosting.Self
{
    public class FileSystemRootPathProvider : IRootPathProvider, IHideObjectMembers
    {
        public FileSystemRootPathProvider();

        public string GetRootPath();
    }
}

I'm not sure how to use.

update: I just figured out anything I need to load can just be read/written from the bin/relase/ directory. Is that the assumed way to do it in a Nancy Self Hosting environment? I guess that would make sense.

You can take a dependency on IRootPathProvider and use that to call GetRootPath() that will give you the root of your application and you can add from there (I would recommend using Path.Combine)

I ALWAYS use path.combine. it only took one production quality project to make me never combine path strings manually ever again =) – FlavorScape Feb 24 '13 at 01:01
should IHideObjectMembers be implemented? – cnd Jul 15 '14 at 05:49
Thought that was just for intellisense/visual studio, so it's up to you. That just hides the base functions for code completion. – FlavorScape Jul 15 '14 at 15:49
If it's in a `NancyModule` then just add `IRootPathProvider` to your constructor and you can start using it to call `GetRootPath()` – TheCodeJunkie Aug 25 '15 at 12:56
@TheCodeJunkie How can we access IRootPathProvider from the Bootstrapper ? – tobiak777 Jun 24 '17 at 17:04
@reddy in `ApplicationStartup`: `var rootPathProvider = container.Resolve();`. – Endy Tjahjono Jan 05 '18 at 07:16

If you need this in a static class (such as an HtmlHelpers extension) where the IRootPathProvider dependency can't be injected, at least AFAIK, you can use AppDomain.CurrentDomain.BaseDirectory which is what DefaultRootPathProvider uses under the hood for .Net 4.x: https://github.com/NancyFx/Nancy/blob/master/src/Nancy/DefaultRootPathProvider.cs
