Hidden Features of C#
-
well seriously, you should read this book http://blog.oncode.info/wp-content/uploads/2008/02/rtfm.png[^] perhaps you didn't read well, because after 17 iterations you should have your relevant information, if not, read it 17 times again

Hi, this is not a hidden feature. This feature is documented ;)
-
sorry, but if you look at the MSDN C# Reference http://msdn.microsoft.com/en-us/library/618ayhy6.aspx[^] and hit C# Operators you can see them at glance. Looks like there is some RTFM to do :-D

I know, actually this is title of stackoverflow topic! There are keywords that are not documented.

Tried reading the language specs? That documents them. I had a quick look at the StackOverflow link - if these are hidden features they can't have been looking at anything beyond C# in 5 :laugh: minutes.

Hidden Features of C# Personally I like ?? operator and started using it since then:
private IList<Foo> _foo;
public IList<Foo> ListOfFoo
{ get { return _foo ?? (_foo = new List<Foo>()); } }Hidden? You have to be kidding me. Each iteration of C# has been preceeded with a barrage of evangalism and education, and to be unaware of things such as "as" can only mean one has had one's head firmly buried in the sand. readonly? hidden? :doh:

Actually I just copied the stackoverflow title! have you guys noticed __makeref ? http://stackoverflow.com/questions/9033/hidden-features-of-c/9125#9125[^] more info: http://www.eggheadcafe.com/articles/20030114.asp[^] There are good tricks too. Worth reading that, but should I change this topic title?!

Actually, it does seem very obscure. Much like this operator I stumbled upon the other day:
int x = 5 + 1;
Much to my surprise, this operator actually performs TWO distinct operations, depending on context!
string x = "5" + "1";
My God! An operator that BOTH adds integers AND concatenates strings. I believe it even works on non integral types. Truly a Jack of all trades! Disclaimer: this post is a joke.

Do I sense some sarcasm... :)
I wasn't, now I am, then I won't be anymore.

It's a good thing it's obscure, because the second use gives a result of 51 when the correct answer is 6. ;)
Chris Meech I am Canadian. [heard in a local bar] In theory there is no difference between theory and practice. In practice there is. [Yogi Berra] posting about Crystal Reports here is like discussing gay marriage on a catholic church’s website.[Nishant Sivakumar]

Aw noo! I must go back and correct all teh codez for my area summation algorithm! I don't want my boss to see this mistake... time for an area 51 cover-up.

Actually,, undocumented keywords do exist in c#. They are undocumented as MS don't want us to use them (e.g. there is a high potential for a visit from the FU Fairy). See http://davesbox.com/archive/2008/12/29/documenting-undocumented-features.aspx[^]
Sort of a cross between Lawrence of Arabia and Dilbert.[^]

That looks like an oxymoron - but that's a debate about semantics. There are identifiers, such as __reftype, that act as though they are keyword in .Net but are not specified as keywords in the C# language. These are implementation details so may not be 'keywords' in e.g. Mono. I don't know of a better way to describe such identifiers than 'undocumented keywords' but the phrase leaves me with bad taste - rather like beetroot. :)

RTFM is done for C#2 and upgraded for C#3 and 4, but still seems I missed some features during upgrade! it happens ;P
What is RTFM :cool::
