Negative Null is a Nullable Int
I was coding along today and I meant to type in this:
if (this.Update() != null)
But I actually typed in this:
if (this.Update() != -null)
Notice the minus sign before the
null keyword. When I compiled this, I got a very interesting error message:
Operator '!=' cannot be applied to operands of type 'MyItem' and 'int?'
Huh. I didn't know that a negative null was actually a nullable integer!
