ManagementObjectCollection usage

I am trying to use the ManagementObjectCollection class to get some system information. However, the attcahed code snippet gives me the errors:
"ManagementClass not defined"
"ManagementObjectCollection not defined"
"ManagementObjectCollection.ManagementObjectEnumerator" not defined.

From what I can see in MSDN, I have to import System and System.Management to get these classes.

I have both imports in my code but still get the errors.

I am using Visual Studio.Net (Visual Basic 2008) on a WinXP SP3, .Net 3,.5 PC.

Can someone please advise what I am missing.

Thanks

Dim ManClass As ManagementClass = New ManagementClass("Win32_ComputerSystem")
Dim ManObj As ManagementObjectCollection = ManClass.GetInstances()
Dim ManOblCollection As ManagementObjectCollection.ManagementObjectEnumerator = ManObj .GetEnumerator
ManOblCollection .MoveNext()
s = ManOblCollection .Current.Properties("CurrentTimeZone").Value.ToString()

I'm still learning. I have the following at the top of my code:

IMports System
IMports System.Management

Is that differenmt from adding a reference?

Thank you. I found that I had to add theimports as references even though I had them at the top of the source file. Works a treat.
