Hi!


I have a xamarin application where i want to upload an image into a folder on the server-side.Everything seems to be working properly except for the fact that the image won't save.I checked the api and it's ok,I checked the server-side,the method alone works fine using Postman as it uploads the image in the folder but when i try to upload an image from the client-side,it gets lost somewhere along the way.I have no error what so ever that could point me to a possible mistake in my code as the image is taken from the android emulator,converted into a byte array,stored into the database,but nowhere to be found in the folders' server side.
This is my Model class:

<pre> public  class User
    {
        public int IdUser { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
        public string Password { get; set; }
        public string ConfPassword { get; set; }
        public DateTime Created { get; set; } = DateTime.Now;
        public DateTime? Dob { get; set; }
        public byte[] Picture { get; set; }

        public virtual ICollection<Login> Login { get; set; }
    }

Server-side controller api method:

<pre>  [HttpPost]
        public async Task Post(IFormFile file)
        {
            if (string.IsNullOrWhiteSpace(_environment.WebRootPath))
            {
                _environment.WebRootPath = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot");
            }

            var uploads = Path.Combine(_environment.WebRootPath, "uploads");

            if (!Directory.Exists(uploads)) Directory.CreateDirectory(uploads);

            if (file.Length > 0)
            {
                using (var fileStream = new FileStream(Path.Combine(uploads, file.FileName), FileMode.Create))
                {
                    await file.CopyToAsync(fileStream);
                }
            }
        }

client-side web service:

<pre>  public async Task UploadPictureAsync(MediaFile image,string fileName)
        {
           string pictureUrl = "http://10.0.2.2:5000/api/UploadPicture";
            HttpContent fileStreamContent = new StreamContent(image.GetStream());
            fileStreamContent.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("form-data") { Name = "file", FileName = fileName };
            fileStreamContent.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/octet-stream");
            HttpClientHandler clientHandler = new HttpClientHandler();
            clientHandler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; };
            using (var client = new HttpClient(clientHandler))
            using (var formData = new MultipartFormDataContent())
            {
                formData.Add(fileStreamContent);
                var response = await client.PostAsync(pictureUrl, formData);
                if(response.IsSuccessStatusCode)
                {
                    //
                }
            }
        }

and the VM command method:

<pre> async Task UploadImage()
        {
            
            await CrossMedia.Current.Initialize();
        // await CrossPermissions.Current.RequestPermissionAsync<CameraPermission>();
            var mediaOptions = new PickMediaOptions()
            {
                PhotoSize = PhotoSize.Medium
            };
            var selectedImageFile = await CrossMedia.Current.PickPhotoAsync(mediaOptions);
            using (var memoryStream = new MemoryStream())
            {
                selectedImageFile.GetStream().CopyTo(memoryStream);
                Picture = memoryStream.ToArray();
               await service.UploadPictureAsync(selectedImageFile,selectedImageFile.ToString());
            }
            if (selectedImageFile == null)

            {
                await Application.Current.MainPage.DisplayAlert("Error", "Could not get file", "ok");
                return;
            }
        }

Did anyone face this kind of situation and knows how it can be resolved?Any help would be appreciated.
