Detecting service packs

[Mark Rae]

Hi,

I'm looking for a reliable way of detecting the version of Windows that the
..NET framework is installed on, specifically the service pack. Currently,
I'm using System.Environm ent.OSVersion and pulling the Major, Minor, Build
and Revision properties out of that.

However, e.g. Windows XP returns exactly the same values for no initial
build, SP1 or SP2.

I found the following site:
http://www.c-sharpcorner.com/FAQ/OSV...ngEnvClass.asp which makes
reference to a .CSD property of System.Environm ent.OSVersion, but I don't
think that's correct.

Is a call to the WinAPI GetVersionEx function the only way to achieve this?

How about using WMI?

-- Code Start --
ObjectQuery oQuery = new System.Manageme nt.ObjectQuery( "SELECT CSDVersion
FROM Win32_Operating System");
ManagementObjec tSearcher oSearcher = new ManagementObjec tSearcher(oQuer y);
ManagementObjec tCollection result = oSearcher.Get() ;
foreach (ManagementObje ct mo in result) Console.WriteLi ne
(mo["CSDVersion "].ToString());
-- Code End --
