回答1:

If you have a BitmapSource you can use BitmapSource.CopyPixels Method (Array, Int32, Int32)

Or alternativeley, for example if you need a ARGB byte sequence:

var bmp = new WriteableBitmap((BitmapSource)source);
byte[] pixels = bmp.Pixels.SelectMany(p => new byte[]
{
    (byte)p,
    (byte)(p >> 8),
    (byte)(p >> 16),
    (byte)(p >> 24)
}).ToArray();
