title: How to open a file from Memory Stream
body: <p>Is it possible to open a file directly from a <code>MemoryStream</code> opposed to writing to disk and doing <code>Process.Start()</code> ? Specifically a pdf file? If not, I guess I need to write the <code>MemoryStream</code> to disk (which is kind of annoying). Could someone then point me to a resource about how to write a <code>MemoryStream</code> to Disk?</p>
