It matters when you want to pass the value to a function that accepts just int, not a nullable int. Let's say you have this : private int NoNullable(int val){ return val + val; } In order to call this function you must use one of the two ways after the if condition: NoNullable(amount); Or, NoNullable(nullable.value);
