Why can't I get Network drive info with elevated permissions?

I am providing code to show you the problem.  I have network drives on my system and when I run this app under the debugger in Visual Studio 2010 the result is nothing.  If I take the executable aside and run it as Administrator still nothing.  But if I do not elevate the app the results are there. What am I doing wrong?  Why would elevating an app cause it to restrict the results?  That makes no sense.  Thanks for any help!
