Bitmap Serialize

So I've been tasked to fix a database full of pictures that weren't displayed, no matter what I tried, the Image (Stored as a byte array) was always invalid.

So I thought I'll save the file and see if I can get an image fixer on it, I just used a FileStream opened it and wrote to it

var fileStream = new FileStream("output.dat", System.IO.FileMode.Create);
fileStream.Write(bytes, 0, bytes.Length);
fileStream.Close();

Upon opening the file, I was expected to see something beginning with "Exif" or "JPG" or something, but what I saw was even better.

System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a

A, ha!! The actual Bitmap object was being saved, not the actual Image, therefore I put together a bit of code to get me the Image and put it back as the Image for my code to work correctly. In this case, I could fix it, but if I couldn't I'd have to have a bit of a legacy converter for it.

public static Bitmap BitmapObjectToBitmap(byte[] data)
{
  using (var ms = new MemoryStream(data))
  {
     var bf = new BinaryFormatter();
     Bitmap bitmap = (Bitmap)bf.Deserialize(ms);
     return bitmap;
  }
}

Then the working code for the Image to Byte Array

 public static byte[] ImageToByteArray(Image image, ImageFormat format)
{
 using (var ms = new MemoryStream())
 {
  
  var bm = new Bitmap(image);
  bm.Save(ms, format);
  return ms.ToArray();
  
 }
}

Comments welcome!!
