Explicitly setting Interger variable to NULL before passing to dat

I have a variable declared as integer which I populate based on the value on
a grid. This value can be NULL. However, I get an exception when I try to
save this value to the database even though the paramaeter has been declared
with a default of NULL in the stored procedure. Is there a way I can set an
integer value explicitly to NULL, something like
var = system.dbnull.value

If you are using C# 2.0, then you can use Nullable<int> for your variable,
also available as int? notation.
