How to convert Bitmap image to byte array in wp7?

Question

using (MemoryStream ms = new MemoryStream())
{
    image.CreateOptions = BitmapCreateOptions.None;
    image.UriSource = new Uri("/Images/chef.png", UriKind.Relative);              

    WriteableBitmap LoadedPhoto = new WriteableBitmap(image);
    LoadedPhoto.SaveJpeg(ms, LoadedPhoto.PixelWidth, LoadedPhoto.PixelHeight,0,95);
    ms.Seek(0, 0);
    byte[] data = new byte[ms.Length];
    ms.Read(data, 0, data.Length);
    ms.Close();
 }

I am getting NullReferenceException at image, but my path is also correct and image also exists.

WriteableBitmap LoadedPhoto = new WriteableBitmap(image);

Is anything goes wrong.

I don't see the line `BitmapImage image = new BitmapImage()` or anything similar? — xmashallax, Sep 16 '13 at 12:21
