Yup,
Castdoesn’t do that. Basically it just does reference conversions and unboxing conversions – not conversions between different value types.Use this instead:
Note that pre-.NET 3.5 SP1,
Castdid some more conversions than it does now. I don’t know offhand whether it would have worked then or not, but it definitely doesn’t now.
