Hello all.

In reference to the CSLA 2.0: We currently use a custom datareader that handles nullable types. Looking at the safedatareader, I couldn't tell how it handles assigning to a nullable type. Before we go ahead and extend the safedatareader on our own, I was wondering if I missed something. I searched the old and new forums but didn't find any answer.

Does anybody have any advice or suggestions?

Thanks,

Brent

I use nullable types a lot with CSLA 2.

I do this sort of thing with SafeDataReader

_myVar = (DateTime?) dr.GetValue("MyVar");
_myVar = (int?) dr.GetValue("MyVar");

... etc ...

Not perfect I guess but it works just fine. The type of object returned by dr.GetValue can only be the correct column type or null so there is no real danger of the cast failing at runtime.

Thanks Ross.

That looks good. The custom reader was doing an internal cast so casting in the object will work just as well.
