In any .NET application where you are *only* accessing code *that you have written* would you use System.Reflection or System.CodeDom? That's a better question than you may think. ;-)
For database work, I'd agree with Michel and use System.CodeDom wherever possible. That simple parser I mentioned earlier can convert VFP table-driven stuff to static C#. It's big, but it works.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
