Zdeslav Vojkovic wrote: ever tried to foreach over a collection of value type instances, and change something? you can't, you must change the the whole object That sounds correct. A value type is immutable. IIRC that appies to value types in any OO language (if that condition does not apply then it is not a value type in the OO sense)

an integer is a value type (in .NET sense). this would mean that you can't change an integer. if you follow the same logic this should be illegal:
System.Drawing.Rectangle rc = new System.Drawing.Rectangle(5, 10, 15, 20); rc.Offset(1,2);if i can offset a rectangle this way, it should also be possible to do it inside foreach statement. -

That is why I rarely extends those interfaces IList is what i meant. i'm not using C# for last six months, so i already started to forget details :) jan larsen wrote: Que?, I don't think I can see the problem. What exactly is it that you want to do with the value type instance? And more important, how often do you actually have a collection of value types i find it really annoying that something like this is impossible:
int[] ar = {1, 2, 3}; foreach (int i in ar) { i = i * 2; }of course, this is just a simplified example, but every so often i have a need to iterate over some simple data and change them. even worse, if it were reference type, it would also be impossible because the returned data is not a reference to real data, but to copy, which is essentially read-only, so foreach is generally usable only in read-only scenario. this just doesn't compile:string[] strs = {"aa", "bb", "cc"}; foreach (string s in strs) { s = s + "_x"; }jan larsen wrote: I totally disagree, using is so intuitive to use i know what's the use for "using" and that it is far better than try-finally, i believe that there is no need for both in the first place, and that it is just a hack. i simply don't like littering the language with workarounds for framework issues. i like the way it is done in C++/CLI when the object is automatically disposed when it goes out of scope (and i'm aware why this is not supported in C#)Zdeslav Vojkovic wrote: i like the way it is done in C++/CLI when the object is automatically disposed when it goes out of scope (and i'm aware why this is not supported in C#) Yes, but if you ever take an object allocated on the stack and store its address (by pointer or reference) as an element of a collection (for later retrieval), BOOM!

I am dead serious. VB is bad, but C# is a disaster. See this presentation[^] by Bjarne Stroustrup: The dilemma is real •The most elegant languages –(e.g. Smalltalk, ML, Haskell, Common Lisp) –Are not applicable for many important application areas –Are not efficient for many important problems –Are apparently not manageable for most programmers •The most efficient languages –(e.g. C, C++, Fortran) –Encourage low-level messing/hacking –Have problems expressing some important problems elegantly –Are hard to “restrain”for reasoning/analysis/transformation •Many language are neither fish nor fowl –(e.g. Java and C#) –Neither elegant nor efficient –Not applicable for many important application areas
My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it.
C# is a disaster for anything aside from windows programming, and if you are using it for anything else, you're insane. As a windows application development language, C# (and .NET) are very nice indeed. "The Yahoos refused to be tamed."

Hello, Interesting discussion going on here... Which language, in your opinion (anyone else is free to answer this too ;)) is the next best language for a VB .Net programmer to learn? Is C# a good introduction into C++? Or should I skip C# all together?

Programmer2k4 wrote: Is C# a good introduction into C++? Or should I skip C# all together? Frankly, both. They both have their strengths and weaknesses. It's probably better to learn their nuances, like the difference between templates and generics (C# 2.0), pointers vs. boxing/unboxing, managed vs. unmanaged, multiple inheritance vs. interfaces, etc. My 2c.

Why do you exclude web application development from that? ASP.NET with C# is like an orgasm on tap.

-- Stewie Griffin:) To be honest, the last time i actually used it was a few years back. I was taking a class on web-dev with ASP, and getting bored with the projects... so for one i did a partial Forth interpreter in ASP, and implemented the rest of the project using it. Not the most modern of languages i guess, but hard to beat for pure fun...

I remember my dad messing around with Forth at home around 15-20 years ago maybe. He got all excited about improving some algorithm. I think I mumbled "That's nice" around a mouthful of King Vitmain cereal. :) Never got much beyond a quick look at his code, I was too busy playing soccer at the time. BW
