Creating nullable data types in c#

Question

I have a data type called

public enum Gender { Male, Female }

But some case i need to pass the vale for the gender as empty. So how can i create nullable Gender in C#

Answer 1

Either

Gender? myGender = null;

Or

Nullable<Gender> myGender = null;

The first variant is exactly the same as the second, but it just C# syntactic sugar to ease the readability of nullable variables.
