Convert Image into byte array in Xamarin.Forms

Question

I need to pass an image (Image _thresholdedImage) like byte array... I don\'t know how I can do this. Any idea? Thank you!

_thresholdedImage.Sou

It turns out that you can convert the MediaFile object to a byte array. So no need to convert the file to ImageSource or Image.

var photo = await CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions() { });

byte[] imageArray = null;

using (MemoryStream memory = new MemoryStream()) {

    Stream stream = photo.GetStream();
    stream.CopyTo(memory);
    imageArray = memory.ToArray();
}
