What Language Features Do You Miss In C#?

Or, you could put both operations in methods and call them?

Not great for all scenarios. FYI, I am talking about "goto case", not "goto label". The former is limited in scope and so isn't plagued by the spaghetti caused by the latter. :)

I could but then my keyboard would jump up and strangle me with the cable. :)

[Marc A Brown]

Ah, that's what you meant. I hadn't considered such a thing.

[OriginalGriff]

That's not very nice at all: since cases aren't named, they would either have to be anonymous (in which case a maintenance PITA if I insert a case between this and the next) or "goto case myEnum.myValue" which is kinda repellent as well. :laugh:

Compile-time templates, C++ style. Generics are great, unless you want to restrict a generic type argument to be "addable" or something like that. Probably not going to happen, given the direction it's taking. Also nice, "break out of named-loop", Java-style.

Support to use untyped generics. That is, everytime I have a generic type I also create a non-generic interface so I can use the object without using reflection/dynamic but with a considerable good speed. But it would be great if that was automatic. That is: List<int> only accepts int. I receive it in as a List<> parameter. In this case, all the T parameters, usually seen as int, could be seen as object, doing the casts that are necessary... Well, for the List itself we can already use the IList... but it will be great to have such resource so we could avoid creating interfaces to allow "the more generic, non-generic" call (that is, more generic because it is untyped... I also hate the name generic... it should be typed... a typed list... the ArrayList is the generic one... hehe).

Hmm. So, for every generic, you also get a Foo (with a better name)? Yeah, I could see how that might be handy for reuse: Bag, Bag etc. shoved into a generic Sort(Bag) method?

In my case, actually, for every Foo<T> I also have an IFoo where the parameters are as object instead of T. I think java have such feature (I know, in java the implementation is completely different)... I think they use: Foo<?> to say that they don't know the type being used. It is slower than having it rightly typed, but it is faster than having it as dynamic or through reflection.

My answer is always multiple inheritance. Times that I would use it are rare. But when those times come up man do I ever want that.

Something from Transact SQL – the “in” clause. Something like:

if(myShoeSize in (16, 12, 17, 32) )
{
imAMutant = true;
}

There is .Contains.

A goto case is not a goto. But, yes, I don't like break in a switch; in my opinion break should only be for loops only.

HashSet

[PIEBALDconsult]

Method-scoped variables like in VB (static). Defining Extension Methods by applying the Attribute like in VB (rather than this). A proper assignment operator like in Pascal := :-D A proper define directive like in C/C++ # define Pi 3.14 Support for enum in where clauses for generic types -- class C<T> where T : enum ... No default modifiers (public, private, virtual, sealed, etc.). Multiple Inheritence would be good too.

[Single Step Debugger]

Yes I know. We can also implement it in C++ using operator overloading. But the point is for a language future, not a pattern, collection or utility class.

This one is type dependent and not a language future but some class method. Same as Split() (very useful method by the way) or IsNullOrEmpty() for example.

Yet HasSet allows other operations, such as union and intersection; would you argue for syntax to allow every such operation? I wouldn't.

What I would like to see in the language: - Destructors that destruct (not the silly Dispose() stuff) [you can easily trigger local garbage collection with an exit from scope] - Ability to use arrays with non-zero origin - inline operator||(), inline operator&&() which implement short circuit logic
