C# Irritation

Why do you need it though?

To indicate design intent as much as anything. A lot of my C++ follows a kind of functional approach (i.e. immutable state - I guess it's most like the 'do' notation that Haskell uses for monadic types). I find it makes my code more likely to be correct than modifying state willy-nilly.

I don't think it's fair to blame C# for the misspelling; it's really the fault of the framework. Any language targetting the framework would have the same problem. Having said that ... if I was writing the language I'd make seamlessly correcting human-language mismatches a part of the spec. :-\

Yes, the rationale for C++ is increasingly "if you can't do it in anything else, you can do it in C++." And IMO C++ ought to be relegated to such uses.

Good points :) If they want C++, WTF are they using C#? ;P

In this particular case, WPF. And to be honest, I'd rather be using Haskell or Python :-)

I came from a heavy C++ background into C#, and things went a lot smoother for me when I leaped the metal hurdle of "C# ain't C++". I agree, C++ lets you do a lot of things that make sense, but c# simply isn't *that* similar to C++.

I think you are fighting OO and trying to write old style c/c++. Just let go and do what MS calls OO and you will get it.

You could well be right - I used to be an OO true believer, but I saw another way[^] and have strayed :-)

They still haven't produced a coordinate system where Y increases as you go up.

And they are probably not going to. Very few, if any desktop windowing systems use a left/bottom origin point. I'm pretty sure a big part of that is text layout, since text, for the most commonly used languages anyways (English, romance languages, slavic languages, etc), lays out left to right, top to bottom. The only desktop system I've seen doing this is NeXTStep/Cocoa, and even there you have the option of telling the framework you want the coordinates flipped for a specific view/control.

Oh yeah. Easily one of the more bone-headed things they did with C#. Until you remember that C# was designed for VB programmers, who are used to just making copies of everything they don't want modified... ;)

Adding const wouldn't actually change anything. The only benefit it would give is a compiler warning if you tried to change the value. But you shouldn't be changing the value anyway if you want it to be readonly.

Scenario: Method returns reference to internal object. This object represents a fundamental type in the domain of this particular app; there are hundreds of thousands of unique instances and they're used all over the place. At one point in its lifetime, it was mutable - special loader classes pulled data into it from many disparate sources, checking and double-checking, correcting and re-correcting. Therefore, it has public mutator methods. But at this point, it is to be considered immutable. C++: method would return a const reference. Any naive caller attempting to modify it would trigger a compiler error. C#: method must return interface rather than direct object reference, or rely on callers to Do The Right Thing, or set some dodgy "done changing state" flag internal to the object itself and implement const checking at runtime.

My background is just plain C and I never used const there so I have no trouble understanding const and readonly in C#. Additionally, in the snippet you show, I wouldn't declare the local variable in the loop at all. I'd rework the entire thing to be more like:

private void PerformTests()
{
ActiveEvents actualEvent ;

do
{      
    switch ( actualEvent = WaitForEvent ( ActiveEvents.ShouldStart ) )
    {      
       ...
    }
}
while ( actualEvent != ActiveEvents.ShouldExit ) ;

return ;

}

Why have one .NET library (Math) which works with radians and another (Drawing2D) which works with degrees?

Yeah, and don't forget whilst. :rolleyes: :)

My latest C# extension method:   public static bool In<T>(this T value, params T[] values)   {       return values.Any(v => v.Equals(value));   } Example:   bool valid = answer.In("Yes", "No", "Dunno");

Yes, and that naive caller (who's also foolish and stubborn) soon discovers that he can cast away constness and get away with murder. :-)

This is the way I would do it (which the above guy can also cast away if he wants).

I would phrase it that C# has totally different design constraints.
