If you're using Map Guide Enterprise 2010, look at Dev Guide manual, between pages 53 - 55. There's an example of how to select a feature. You can find it at %programfiles%\Autodesk\MapGuideEnterprise2010\WebServerExtensions\Help.
I think you can find the same file (DevGuide.pdf) if you're using another MapGuide's version.
You're getting the layer but you're not reading it. Check the method ReadNext().
