How to use Conditional Operation with Nullable Int

Question

A small problem. Any idea guys why this does not work?

int? nullableIntVal = (this.Policy == null) ? null : 1;

I am trying to return null

Answer 1

This works: int? nullableIntVal = (this.Policy == null) ? null : (int?)1;.

Reason (copied from comment):

The error message is because the two branches of the ?: operator (null and 1) don't have a compatible type. The branches of the new solution (using null and (int?)1) do.
