C# or VB.NET?

Hi,

I am a beginner in .NET. I have been coding in plain asp before, using
VBScript, and now when i'm migrating to .NET, i obviously chosed VB.NET.

But.... when i see code samples on net, they are mostly in C#, i also saw a
post in this newsgroup where someone mentioned that it was a very "heated
topic back in 2002 about VB.NET vs C#".

So, my question is... what was the result of that topic?
What is best to go for, VB.NET or C#? and why?

Thanks and regards

beginning dumping those bad habits from the beginning rather than
"knowing" how you can do something and it be bad. This is even more
true with VB since they carried over the functions from older versions
into .NET (i.e. LTrim() Mid() cInt) whereas the .NET way is
different.
But, see, this is what I don't get. And I think C# folks put out a lot of
misinformation about this. Mid, Trim, etc. are suppossed to HELP. They have
no functional equivalents in .NET. No, Substring(...) isn't the same because
1) you need to make sure the string isn't a null reference first, and 2)
exceptions are thrown if you pass values larger than the string. So
everytime you'd like to do the equivalent of Left(...) you have to do:

if (str != null)
{
if (str.Length >= 6) {
str2 = str.Substring(0 , 5);
}
else {
str2 = str;
}
}
else {
str2 = string.Empty;
}
How does that beat Left(str, 5)? Ah. You can write your own function, sure.
But, I can't count the number of different times I've seen this done 3
different ways by 3 different C# developers in the SAME project who didn't
realize another developer had already written it. That's BAD.

And what's this .NET way for CInt that mention? All CInt is shorthand for
CType(var, Integer)... which is a more robust inline compile operator (a
cast, not a function call) that mimics System.Convert( object,
IFormatProvider ) (a function call). The VB way produces faster msil than the
equivalent.

>Side 2 : You'll be more likely to bring bad habits with you, most of
which
resolve around non OO practices.

This is probably the best argument against VB. Nothing was worse than
working with a bunch of programmers that went from VB6 to .NET with no
learning at all. Every single horrible thing they could do in VB6 (it
was bad then too) went directly over to .NET. When you force yourself
to learn a new language you can to wield it the correct way from the
beginning dumping those bad habits from the beginning rather than
"knowing" how you can do something and it be bad. This is even more
true with VB since they carried over the functions from older versions
into .NET (i.e. LTrim() Mid() cInt) whereas the .NET way is
different. The advantage to going to C# and having a VBScript
background is you should be able to read/write VB.NET fairly from
knowing C# and VBScript while it doesn't work as well the other way
(only VB with no C# learning).

The thing is, having a background in VB, you will get a quicker start in
..Net, using VB.Net. I did and it worked well for me.
I know there are a lot of sites with C# samples, but I can think of one with
mainly VB.Net (hint)

Having said all that, I don't see why, once you get started, and somewhat
understand the basics, you don't also try C#.
It's not a One or the Other type of situation.

If you know both, you become more knowledgeable. Therefore, at that point,
if you want to stick with one or the other, you can make your own decision
based on what you've learned yourself.

>I would suggest you begin with C#, for no other reason that it will force

I think this point has alot of weight. I do still think about "how i would
have solved a perticular issue in classic ASP"

Why i even touched this "heated topic" here is because i just wanted to
know what is "best". During my learning also i've been trying to stick
with "best-practices". using n-tier application structure etc...

But i must say, VB.NET and C# is not a "choice" one can make. One way or
another, in the end i'll actualy be having my hands on both.

Thank you everyone for very helpful input. I've learnt alot from this
discussion.

>>>Why do you actually have to choose at all...?
Maybe that was wrong choice of words. "Best way to begin" maybe :-)

Fair enough.
>>But since you are an MVP in asp.net. What would you suggest a beginner
with my background. VB or C# to begin learning?

I would suggest you begin with C#, for no other reason that it will force
you to think in an object-orientated .NET way and prevent you from
carrying over any of the VBScript baggage...

I've known quite a few new (to .NET) developers who have begun with
VB.NET and then switched to C# - I've never known the reverse...

And, if ever you find yourself thinking "How would I have done this in
ASP Classic?", then have a five-minute break and approach the problem
again from the beginning... :-)

But, this is just one of example of VB's "moreness" and robustness
compared to C#. :)
My understanding is that those functions are there for the VB->VB.NET
conversion utility, and also so that VB programmers can use vb.net without
having to change their coding syntax, style or methods.

Just cos you can doesn't mean you should.

Plus, VB has the "With" keyword.... which is beautiful. C# doesn't.
Now there I fundamentally disagree with you! I think the With keyword is
positively horrible...

As you know, a 'with' statement would make C# more complex. As you will also
know, VB.NET had to add new language syntax to address the potential
ambiguity between a local variable (Text) and a property on the "with"
target (.Text), and other ways of solving this problem also introduce
language complexity.

A different approach is to push a scope and make the property hide the local
variable, but then there's no way to refer to the local without adding some
escape syntax.

That's wrong. The VisualBasic.dll library (where those functions reside) is
not the same as the VB Compatibility Library (that has truly deprecated
things like old VB.Classic control arrays). Stuff in the Visual Basic.dll
library are fully supported, and completely rewritten stuff.... along with
new stuff like the very handy "My" namespace, which resides in the same
library with Left/Right/Mid.

"Just cos you can doesn't mean you should" implies there's something wrong
with the function (whose equivalent you'd find in many a C#'s developer's
"snippet's library"... all different... and all redundant... and often
buggy). If the wrapper was written for you (by the Microsoft VB.NET
Team).... it's fast (rewritten in .NET), it works well, and it has (ohhhh I
dunno over 25 years worth of track record), why not use it?

Again, as I noted in another thread... the Microsoft.Visua lBasic .NET
namespace is not the same as the VisualBasic.Com patibility namespace.

What "new language syntax" are you refering to? With (statement) is just
shorthand. I'm not aware of any caveats with it... or ambiguity between what
appears in the block and what's scoped....
Please explain.

As for ambiguity between scoped variables... (Me, the equivalent of C#'s
"this" removes all ambiguity).

Ah. I see. You just copy and pasted.... verbatim. That doesn't explain what
the "new language syntax" means. Do you know what that post means and thus
why you don't like it? I sure don't.
