this is my code:

 public IActionResult Details(int id)
 {
     List<SugestionViewModel> sugest = new List<SugestionViewModel>();
     SugestionViewModel s = new SugestionViewModel();
     var shoes = _db.Shoes.Find(id);
     List<string> picname = new List<string>();
     string[] FilePath = Directory.GetFiles(Path.Combine(_env.WebRootPath, "Images\Shoes\" + shoes.Code_Fani));
     foreach (string file in FilePath)
     {
         picname.Add(shoes.Code_Fani + "/" + Path.GetFileName(file));
     }

     ViewBag.Image = picname.ToList();
     var VideoPath = Path.Combine("wwwroot\Media\IGTV\" + shoes.Video);
     if (System.IO.File.Exists(VideoPath))
     {
         string[] FilePath2 = Directory.GetFiles(Path.Combine(_env.WebRootPath, "Media\IGTV\" + shoes.Code_Fani));
         ViewBag.media = shoes.Code_Fani + "/" + Path.GetFileName(FilePath2[0]);
     }

     var sugestion = _db.Sugestions.ToList();
     foreach (var su in sugestion)
     {
         Shoes shose1 = _db.Shoes.Where(t => t.Group_Id == su.Group_id).Last();
         string[] FilePath1 = Directory.GetFiles(Path.Combine(_env.WebRootPath, "Images\Shoes\" + shose1.Code_Fani));
         s.Name = "کفش مدل" + shose1.Code_Fani;
         s.Image = shoes.Code_Fani + "/" + Path.GetFileName(FilePath1[0]);
         sugest.Add(s);
     }
     ViewBag.sugestion = sugest.ToList();
     if (shoes != null)
     {
         return View(shoes);
     }
     else return NotFound();
