…another question that I feel I should have been able to find the answer to, but probably fail at combining search words for…
How are conditions in a C# if-statement evaluated? If I have
if( A || B )
will B be calculated at all if A is false? (EDIT: I mean if A is TRUE, of course, silly old me…)
(I want to call it “lazy evaluation”, but I might be remembering my terminology incorrectly.)
In this example; yes. But that has probably more to do with your example (the overall if statement could still come out true, if B is true), than what you are asking about. At least it feels like your question has more depth, technically, than what I’m answering here. Did you mean: “Will B be calculated at all, if A is true?”
ZOMGWTFBBQ, yes I did. Thanks for catching that rather silly error!
And the answer is no, B won’t be evaluated at all. It is in fact explicitly mentioned in the pages for and || in the .Net manual:

Ah, great, that’s what I was looking for. As I suspected, I was just searching with the wrong parameters. Thank you for the answer!
And it’s great knowledge for a n00b wannabe scripter like me, who hadn 't even considered things like this. So that means it’s an optimization if you place the simplest-to-evaluate statements first in such an arrangement. Never thought about that. That’s the prize for being self taught. You have no idea what you have missed of valuable information 
Yep! Also, it means you can “safely” do checks like
if(x == null || x.param == null)
without getting a null pointer exception for it trying to get the param in the second check from a null x. Quite handy.
