nullable var using implicit typing in c#?

Question

Is there anyway to have the var be of a nullable type?

This implicitly types i as an int, but what if I want a nullable int?

var i = 0;

Why not support this:

var? i = 0;

Answer 1

var is typed implicitly by the expression or constant on the right hand side of the assignment. var in and of itself is not a type so Nullable<var> is not possible.

Answer 2

Why support it? If that's what you mean, you should say var i = (int?)0; instead.

(Well, you should probably just say int? i = 0, but for more complicated types, etc.)
