        Hi, this is not a hidden feature. This feature is documented ;)

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

          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

            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.

                        It's a good thing it's obscure, because the second use gives a result of 51 when the correct answer is 6. ;)

                                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[^]

                                  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. :)

                                    I think this is not hidden features .. most of C# developers already know this and this is available everywhere.
