HI Sogorka,

If I understand your question correct,here is the link to convert bitmap image to byte array.
Where as in the below link it converts and save it in database.But you need just conversion part.
Try that alone if you want.

And here is the link[^]

Hope this helps you a bit.

Thanks,
Rk

I want to show the converted image in Image Box. But I am not able to show an image in there. This is the code I am using;

Service1Client GetNameFromService = new Service1Client();
GetNameRequest NameRequest = new GetNameRequest();
NameRequest.username = e.Parameter.ToString();
GetNameResponse NameResponse = await GetNameFromService.GetNameAsync(NameRequest);
lblName.Text = NameResponse.GetNameResult.NAME;
byte[] IMG = NameResponse.GetNameResult.IMAGE;

var stream = new InMemoryRandomAccessStream();
await stream.WriteAsync(IMG.AsBuffer());
stream.Seek(0);

BitmapImage image = new BitmapImage();
image.SetSource(stream);
imgUser.Source = image;

ID = NameResponse.GetNameResult.id;

await GetNameFromService.CloseAsync();

I found an alternate way to get the result as a byte[] or a BitmapImage as follows:

C#

private async Task DownloadUrlAsync(string url)
{
  byte[] ByteResult = null;
  BitmapImage BitmapResult = new BitmapImage();
  ImageSource ImageSourceResult = null;
  if (!string.IsNullOrEmpty(url))
  {
    HttpClient client = new HttpClient();
    ByteResult = await client.GetByteArrayAsync(url);  //result as: byte[]
    InMemoryRandomAccessStream ras = new InMemoryRandomAccessStream();
    await ras.WriteAsync(ByteResult.AsBuffer());
    ras.Seek(0);
    BitmapResult.SetSource(ras);
    ImageSourceResult = BitmapResult;  //result as: ImageSource or BitmapImage
  }
}
