Read version from dll file

How do I determine (programmatically) what version of VSTO runtime the user is running?  

My objective is to write out a logfile for a VS Tools for Office, Outlook Addin, upon catching any exception.  My app installs the runtime (a requirement) to C:\Program Files\Common Files\Microsoft Shared\VSTO\8.0\AddinLoader.dll.  I can manually determine the version of this file but I want to do this in code for logging.  Also, I can manually determine the version in the registry in the Update key of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\vsto runtime Setup\v8.0.50727.  I'd rather avoid reading the registry in code in case the user isn't authorized. Is reading the version of a file object the correct way to do this?

I recall doing this in VB6 and am hoping to find a better way in .NET.

Thanks,
Joe

>>VSTO

No idea what that is, but, check out the FileSystemObject's GetFileVersion method.

peetm: I'd been trying that until I read on MSDN that the filesystemobject doesn't provide version info.  (see http://support.microsoft.com/kb/189751)  The alternate solution there was to use the GetFileVersionInfo Windows API which, is what I was trying to avoid.   Isn't that obsolete?  The FileVersionInfo class that PaulHews posted is what I was looking for.
