Determining Exchange Server Version on a System Using C #

Question

Is there a way to determine which version of Exchange Server is running (2007 or 2010) using C #?

Answer 1

Best to use WMI

Answer 2

There is VBScript here that gets the version for all Exchange servers in the domain using WMI and AD. You can convert this logic to the corresponding .Net classes if it is not possible to use it as it is.

For Each objItem in colItems
