Byte Array to Image Conversion

Converting byte array to image in C#

I found a solution that ended up working. It seems that when the initial ImageToByteArray was being done, it was only doing the "1st page" and not all 8. So I used the following code to convert the whole tiff image:

var tiffArray = File.ReadAllBytes(file); //The `file` is the actual `.tiff` file

I then used the following to convert back to an image(The response is a byte[] returned from our API):

using (MemoryStream ms = new MemoryStream(response))
            {
                ms.Position = 0;
                Image returnImage = Image.FromStream(ms);

                var splitImages = ImageHelper.Split(returnImage);//This is to split the pages within the tiff
            }

I read that for the above to work(and I tested it), anything you do to the byte[]you are converting back to an image, must be done within the using, as anything after the using means the image is disposed.
