I want “(int)null” to return me 0

Question

How can i get 0 as integer value from (int)null.

EDIT 1: I want to create a function that will return me default values for null representa

Answer 1

Use null-coalescing operator or ??

Example:

int? a = null;
return a ?? 0; //this will return 0

It's a new feature in C#. It returns the left-hand operand if the operand is not null; otherwise, it returns the right-hand operand.
