How to upload files in MVC C # on the cell phone?

I am making a form in which you have to take a picture and answer on a cell phone. I have researched the best thing that I found is to use HttpPostedFileBase but I get the null parameter on the Internet I have seen examples with only the image but I also need to send a class.

Controller Code

[HttpPost]
    public ActionResult RecorrerAuditoria([Bind(Include = "Id,Answer,Comment,Assessment")] Audit_Question audit, HttpPostedFileBase file)
    {

        if (file != null && file.ContentLength > 0)
            try
            {
                string path = Path.Combine(@"\emxlocal01\LPA\Prueba Luis\Pictures\Audit", Path.GetFileName(file.FileName));
                file.SaveAs(path);
                ViewBag.Message = "File uploaded successfully";
                if (audit.Answer.Equals("Success"))
                {
                    audit.Status = "Closed";
                    audit.DateFinish = DateTime.Now;
                    audit.EmailSent = "noRequired";

                }
                else
                {
                    audit.Status = "failure";
                    audit.EmailSent = "Pending";
                }
                audit.PictureR.SrcPic = path;
                new Conn().RealizarQuestion(audit);
                return View(SessionHelper.CurrentQuestion.FirstOrDefault());
            }
            catch (Exception ex)
            {
                ViewBag.Message = "ERROR:" + ex.Message.ToString();
            }
        else
            ViewBag.Message = "You have not specified a file.";
        return View();
    }

View code

{ enctype = "multipart/form-data"  }))
