I've created an image with GDI+ on my application and now I must convert this image to an array of bytes.

My first thought was this simple code:

public byte[] ToByte()
{
    MemoryStream ms = new MemoryStream();

    bitmap.Save(ms, ImageFormat.Bmp);

    return ms.GetBuffer();
}

The problem with this approach is that when I finally save this image into a file the colors are inverted. What I'm I doing wrong?
