You can get the file out of the DB as a byte[]. That byte array you can put into a System.IO.Stream object. You can save that object to file or pass it to what you want to do with it.

If it's Asp.Net you probably want to show it. In that case I would save it in a temp folder and or link to it or open another window where url = pdf document.

If the user is done with it, you need to delete the temporary file again.

Hope this helps.
