c# - 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.Source = ImageSource.FromStream (() => photo.Source);

var tessResult = await _tesseractApi.SetImage(imageBytes);

I was unable to convert it in X.Forms, instead I use the following code with a dependency service. Thank you to all.

    public async Task<byte[]> GetBytesFromImage(string filePath)
    {
        ConvertImageToBW(filePath);

        // Create another bitmap that will hold the results of the filter.
        Bitmap thresholdedBitmap = Bitmap.CreateBitmap (BitmapFactory.DecodeFile(filePath));

        thresholdedBitmap = BitmapFactory.DecodeFile (thresholdedImagePath);

        byte[] bitmapData;
        using (var stream = new MemoryStream())
        {
            thresholdedBitmap.Compress(Bitmap.CompressFormat.Png, 0, stream);
            bitmapData = stream.ToArray();
        }

        return bitmapData;
    }
