[HttpPost] public async Task UploadImage(IFormFile imageFile) { if (imageFile != null && imageFile.Length > 0) { // Generate a unique file name to prevent overwriting string fileName = Guid.NewGuid().ToString() + Path.GetExtension(imageFile.FileName); // Create a path to store the file string filePath = Path.Combine(_hostingEnvironment.WebRootPath, "images", fileName); // Save the file using (var fileStream = new FileStream(filePath, FileMode.Create)) { await imageFile.CopyToAsync(fileStream); } // Store the file name in TempData to display it on the preview page TempData["ImageFileName"] = fileName; return RedirectToAction("PreviewImage"); } return View(); }
