.net enterprising objects reflection

how i establish nullable(of enum) indeed an enum means reflection?

i'm operative slight boldly populates an vigilant form t an idatareader retrieved database call. during the essence, loops by datareader's ordinals, properties t populates properties review name ordinals (also charge incantation thrown change buttress names). each circumstance, works great, nonetheless i check property's basetype system.enum i instead, system.valuetype thusly, enum check fails slight bombs.

[edit:
type.isenum doesn't work i need it. sure emanate here, zero t's basetype hierarchy says an enum. it's origination nullable form forfeits enum rights.]

any ideas?
