Hi!

I have two question:
My first question is if these two example names 1 and 2 below are the same.
My second question is if it's enought to just write private DateTime?
mAnniversary
1. private DateTime? mAnniversary = new Nullable<DateTime>();
2. private Nullable<DateTime> mAnniversary = new Nullable<DateTime>();

Yes. You could have easily figured that out yourself just by "hovering"
the mouse cursor over the variable name in Visual Studio and seeing the
type name for both.

Enough for what? At the very least, you need a semicolon for the
declaration. But you don't need to initialize the variable in the
declaration, if that's what you're asking. Class member fields are
initialized to their default value by default.

Yes.

If you give it a value later.
