Null value checking of an object inside an object inside an object

If I do:

var a = FirstPossibleNull.SecondPossibleNull.ThirdPossibleNull.FourthPossibleNullValue;

I'd have to check if "FirstPossibleNull" and "SecondPossibleNull" and 'ThirdPossibleNull" is not null to avoid running in a potential error.

Is there a more elegant (and shorter) solution than this sort of check:

if (FirstPossibleNull != null && FirstPossibleNull.SecondPossibleNull != null && FirstPossibleNull.SecondPossibleNull.ThirdPossibleNull != null)

I think it is the best approach! :D – Galma88 May 20 '15 at 15:18

It might be argued that if you've got a particular bit of code that's accessing properties that deep, it might need to be refactored. – James Thorpe May 20 '15 at 15:19
