Converting Bitmap into array

Hi,

  I have this code:

Bitmap hBitmap = new Bitmap(imageList1.Images[0]);
System.IO.Stream imgStream = new System.IO.MemoryStream();

hBitmap.Save(imgStream, System.Drawing.Imaging.ImageFormat.Bmp);

byte[] buffer = new byte[imgStream.Length];
imgStream.Read(buffer, 0, (int) imgStream.Length);

While the retreiving of the image from the image list is good (I can set a picturebox image to hBitmap) the buffer is always empty.  What am I missing?

Bitmap hBitmap = new Bitmap(imageList1.Images[0]);
System.IO.Stream imgStream = new System.IO.MemoryStream();

hBitmap.Save(imgStream, System.Drawing.Imaging.ImageFormat.Bmp);

// this is the missing line:
imgStream.Position = 0;

byte[] buffer = new byte[imgStream.Length];
imgStream.Read(buffer, 0, (int) imgStream.Length);
0

Wow... that would be embarrasing any of the hundreds of lines of code that I researched had actually shown it and I just missed it.  But that isn't the case so I can still walk (moderately) tall.  :)

Thanks
