Conversion of BitmapImage to Byte array

Question

I want to convert a BitmapImage to ByteArray in a Windows Phone 7 Application. So I tried this but it throws the runtime Exception \"Invalid Pointer Exception\". Can anyone

I'm not sure exactly what your problem is, but I know that the following code is a very minor change from code that I know works (mine was passing in a WriteableBitmap, not a BitmapImage):

public static byte[] ConvertToBytes(this BitmapImage bitmapImage)
{
    byte[] data = null;
    using (MemoryStream stream = new MemoryStream())
    {
        WriteableBitmap wBitmap = new WriteableBitmap(bitmapImage);
        wBitmap.SaveJpeg(stream, wBitmap.PixelWidth, wBitmap.PixelHeight, 0, 100);
        stream.Seek(0, SeekOrigin.Begin);
        data = stream.GetBuffer();
    }

    return data;
}
