nulls and dbnull is there more efficient syntax

I am trying to use the solution given here ->

C# ADO.NET: nulls and DbNull -- is there more efficient syntax开发者_如何学JAVA?

But I am working with an int.

Thanks

int? myNullableInt = null;
myIntParameter.Value = myNullableInt ?? (object)DBNull.Value;

Substitute int? for DateTime? then...
