Nope. This is easy, the first time a static method gets invoked, the static constructor is invoked. Yours throws an exception. The second time, the static constructor is not invoked again, so your call succeeds.

Why did you get it wrong then?

I got it wrong? Then, why did you accuse me of cheating?

Hes playing. But you did get the answer wrong.
|

Yes, I finally ran it. I am surprised that the static constructor is called twice. Probably because it is throwing an exception.
|
|
|
|
|
The static constructor is NOT being called twice.
|
|
|
|
|
yeah, you're right. So, when the static constructor first throws an exception, any attempt to use the static methods (or maybe instance methods) rethrows the exception.
I never use static constructors, and such behavior does not make me want to them.
|
|

|

I think the TestStatic.SaySomething will not be called and it will directly go to the catch block.
But the second TestStatic.SaySomething will be called because static constructors are called only once, afaik.
Am I correct ?

erm... No. But well done for not cheating.

So, both me and this guy give the correct answer. You greet him and you accuse me of cheating. You're a plain a**hole.
|
|
|
|

You both got the answer wrong . He was only joking when he asked if you were cheating...
|
|
|
|

He forgot the icon, so I took as a personal attack. 
|
|
|
|
|
That's a bit rude isn't it? Not sure I like you. And neither did I accuse you of cheating. Tut.

Hmmm I am not sure of this.... Anyway, my apologies if I offended you.

Not offended at all Sir.

I didnt think you could compile with a static constructor? I assume i am wrong thou as others have tested? so in which case i would say output is..
HI
Hi 2
Life goes very fast. Tomorrow, today is already yesterday.

Can't compile with a static constructor?! Not sure they'd be much use in the language if that were the case. Sorry, you're wrong too.

hmmm... well as the TestStatic class is not static it can have a constructor, i just didnt know it could be static. but either way any static methods (i.e. SaySomething) can be called without the need to create an instance of your class, which you are not doing in your code. So both calls to the SaySomething method should be successful, can you explain why either would fail? i think not.

Any class can have a static constructor, but it is highly recommended to make sure they never throw exceptions.

what about...
Afternoon Exception
HI
Hi 2
edit: no, that wouldnt happen if an exception is thrown when the program runs then surely it would just crash with the unhandled exception in the static constructor, no?

Ok, well, you have a static ctor which will throw an exception the first time the type is used, so it would be:
Afternoon Exception
Hi 2
Correct?
|
|
|
|
|
Nope!

Rob Philpott.
|
|
|
|

Ok, I rethought.
The ctor fails, and that is bad.
How about
Afternoon Exception
Afternoon Exception
?
|
|
|
|

Good man! And we have a winner. Yep, the type initialiser fails both times - in short an exception in a static constructor is very bad news.
Well done.

Rob Philpott.
