    custom file system issue - how to 'GetUnderlyingFileSystemProvider' in v8?

    hey out there,

    i'm struggling a little with converting a v7 controller that force downloads a media item to v8.

    the v7 code is as follows:

    var fileSystem = FileSystemProviderManager.Current.GetUnderlyingFileSystemProvider("media");

var filePath = fileSystem.GetFullPath(fileUrl);

if (!fileSystem.FileExists(filePath))
{
    LogHelper.Warn<FileDownloadController>("The media item was not found.");

    throw new System.IO.FileNotFoundException("The media item was not found.", filePath);
}

return File(
    fileSystem.OpenFile(filePath),
    MimeMapping.GetMimeMapping(fileSystem.GetFileName(filePath)),
    fileSystem.GetFileName(fileUrl)
);

    the line i'm stuck with is:

    var fileSystem = FileSystemProviderManager.Current.GetUnderlyingFileSystemProvider("media");

    i've been messing around for ages trying to find the equivalent code in v8 and just can't find it...

    the documentation here hasn't yet been updated for v8:

    https://our.umbraco.com/documentation/Extending/FileSystemProviders/

    which leaves me a little stuck! has anyone else hit this issue yet?

    any suggestions, as ever, are greatly received ;)

    Hi Jake

    I reckon in V8 in the constructor for your controller you could inject in the IMediaFileSystem that is currently registered via DI?

    using System.Collections.Generic;
using System.Web.Mvc;
using Umbraco.Web.Models;
using Umbraco8.Services;
using Umbraco.Core.Logging;
using Umbraco.Core.Services;

namespace Umbraco8.Controllers
{
    public class MyCustomController : Umbraco.Web.Mvc.RenderMvcController
    { 
       private readonly IMediaFileSystem _mediaFileSystem;
        public MyCustomController(IMediaFileSystem mediaFileSystem)
        {
             _mediaFileSystem = mediaFileSystem;
        }
        public override ActionResult Index(ContentModel model)
        { 
            // do something with MediaFileSystem
            string fullPath = _mediaFileSystem.GetFullPath(path);
        }
}

    Some documentation on composing here: https://our.umbraco.com/Documentation/Implementation/Composing/ and some examples of injection of services here: https://our.umbraco.com/Documentation/Implementation/Services/

    regards

    Marc

    now why didn't i think of that... think it may have been a case of over thinking the problem ;)

    cheers fella, much appreciated.
