problem z zapisaniem obrazka i jego wyświetleniem

Witam,chcę pobrać obrazek wraz z tytułem itp. ,obraz zapisac do folderu /images/memy/ a następnie pokazać na ekranie obraz wraz z tytułem itp.
W kontrolerze MemyController mam metode Create która powinna zapisac obraz który bede chciał dodać .Nestety przypuszczam że nie działa poprawnie ponieważ po dodaniu obrazka i wciśnieciu Create nic sięnie dodaje ani do bazy ani do folderu -/images/memy/

[HttpPost]
        public async Task<IActionResult> Create(Memy model, IFormFile fileUpload)
        {
            
            if (ModelState.IsValid)
            {
                string pathImgMemy = "/images/memy/";
                string pathSave = $"wwwroot{pathImgMemy}";
                if (!Directory.Exists(pathSave))
                {
                    Directory.CreateDirectory(pathSave);
                }
                string extFile = Path.GetExtension(fileUpload.FileName);
                string fileName = DateTime.Now.ToString("dd-MM-yyyy-hh-mm-ss") + extFile;
                var path = Path.Combine(Directory.GetCurrentDirectory(), pathSave, fileName);

                using (var stream = new FileStream(path, FileMode.Create))
                {
                    await fileUpload.CopyToAsync(stream);
                }

                DateTime dateNow = DateTime.Now;
                model.coverImg = pathImgMemy + fileName;
                model.releaseDate = dateNow;
                model.modifyDate = dateNow;
                db.Memy.Add(model);
                await db.SaveChangesAsync();
                return Redirect("{controller=Home}/{action=Index}/{id?}");
            }
            return View();
        }

a to model Memy

[Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int Id_mema { get; set; }
        public string Autor { get; set; }
        [Required]
        public string Title { get; set; }
        public string coverImg { get; set; }
        [Required]
        public string Description { get; set; }
        public string Category { get; set; }
        [Required]
        public DateTime? releaseDate { get; set; }
        public DateTime? modifyDate { get; set; }
        public int? Like { get; set; }
        public int? Dislike { get; set; }

Odpal pod debuggerem, postaw breakpoint na tym if, zobacz, czy w ogóle "wchodzi" do niego (czy ModelState.IsValid jest true).
Pokaż też swój kod widoku, może tam coś jest nie tak.

sprawdzałem if(ModelState.IsValid) i program nie "wchodzi:w tego if ,dlaczego tak się dzieje?

Będzie szybciej:

var errors = ModelState.SelectMany(x => x.Value.Errors.Select(w => w.ErrorMessage));

foreach (var error in errors)
{
    Console.WriteLine(error);
}

Wydaje mi się, że wystarczy użyć jakiegoś innego modelu do wkładania danych niż Memy

Trochę nie rozumiem,gdzie to powinienem dodać ? albo co zastąpić tym kodem?

Zrobiłeś jak napisałeś i nic nie otrzymałem ,żadnych błędów

  [HttpPost]
        public async Task<IActionResult> Create(Memy model, IFormFile fileUpload)
        {
            if (fileUpload == null)
            {
                ModelState.AddModelError("errFileUpload", "The file upload field is required.");
                return View();
            }
           
            if (ModelState.IsValid)
            {
               
                string pathImgMemy = "/images/memy/";
                string pathSave = $"wwwroot{pathImgMemy}";
                if (!Directory.Exists(pathSave))
                {
                    Directory.CreateDirectory(pathSave);

                    await fileUpload.CopyToAsync(stream);
                }

                DateTime dateNow = DateTime.Now;
                model.coverImg = pathImgMemy + fileName;

            }

            return View();
