How to convert byte[] to BitmapSource in c# WPF

Question

I have a byte buffer (byte[]) of an image. I have to convert byte[] to BitmapSource (System.Windows.Media.Imaging.BitmapSource).

private void WriteAsJpeg(string fileName, BitmapSource bmp)
            {
                JpegBitmapEncoder encoder = new JpegBitmapEncoder();
                BitmapFrame outputFrame = BitmapFrame.Create(bmp);
                encoder.Frames.Add(outputFrame);
                encoder.QualityLevel = 100;
                using (FileStream file = File.OpenWrite(fileName))
                {
                    encoder.Save(file);
                }
            }

How can i convert byte[] to BitmapSource in order to call the above specified function.

//array is a byte[]
 using (var memoryStream = new System.IO.MemoryStream(array))
    {
    var image = new BitmapImage();
    image.BeginInit();
    image.CacheOption = BitmapCacheOption.OnLoad; 
    image.StreamSource = memoryStream ;
    image.EndInit();

   }

`image` will go away at the end of scope, and code formatting is perfectible ;) – Soleil Oct 18 '19 at 13:55

you can use it in this scope :) – Marwen Jaffel Oct 18 '19 at 15:14
Of course, but the point is using the bitmap image and letting go of the stream.You might want to review your code formatting. – Soleil Oct 18 '19 at 16:27
