How do I convert a Bitmap to a byte[]

[Bill Fuller]

I have a Bitmap (bm) that I am able to save using, for example,
bm.Save("file.jpg", System.Drawing.Imaging.ImageFormat.Jpeg). However, I
would like to convert this to a byte array (byte[]). What is the best way to
do this?

It has an overload that takes a Stream as first argument. Pass a
MemoryStream object.

MemoryStream object.

And then after you've saved the Bitmap to that MemoryStream, use
MemoryStream.ToArray() to convert to a byte[].
