When I can use C# over VB.Net. What is the advantage of using c#?

Tamil Nadu people always would
like to speak Tamil and Andhra people Telugu even though they know Hindi and
English. That’s obvious.

 

Sometimes programming languages
are like religions. Developers are so zealous about their language of choice
that they turn a blind eye to other languages.

 

With .NET all language choices
are now just cosmetic and that’s the most important point to understand. After
all the CLR (Common Language Runtime/Managed Runtime) works on IL (Intermediate
Language – Refrain from using MSIL as IL is standardized now) and all .NET
enabled languages compile to IL. So no matter what .NET supported language you
choose there is no difference in the capability in terms of functionality and
(in the right hands) even performance.

 

The choice between C# and VB.NET
is largely one of subjective preference. Some people like C#’s terse syntax,
others like VB.NET’s natural language, case-insensitive approach. Both have
access to the same framework libraries. Both will perform largely equivalently
(with a few small differences which are unlikely to affect most people,
assuming VB.NET is used with Option Strict on). Learning the .NET framework
itself is a much bigger issue than learning either of the languages, and it’s
perfectly possible to become fluent in both – so don’t worry too much about
which to plump for. There are, however, a few actual differences which may
affect your decision:

 

VB.NET Advantages

 

·       
Support for optional parameters – very handy for
some COM interoperability

·       

Support for late binding with Option Strict off
– type safety at compile time goes out of the window, but legacy libraries
which don’t have strongly typed interfaces become easier to use.

·       
Support for named indexers (aka properties with
parameters).

·       
Various legacy VB functions (provided in the
Microsoft.VisualBasic namespace, and can be used by other languages with a
reference to the Microsoft.VisualBasic.dll). Many of these can be harmful to
performance if used unwisely, however, and many people believe they should be
avoided for the most part.

·       
The with construct:
it’s a matter of debate as to whether this is an advantage or not, but it’s
certainly a difference.

·       
Simpler (in expression – perhaps more
complicated in understanding) event handling, where a method can declare that
it handles an event, rather than the handler having to be set up in code.

·       
The ability to implement interfaces with methods
of different names. (Arguably this makes it harder to find the implementation
of an interface, however.)

·       
Catch … When … clauses, which allow
exceptions to be filtered based on runtime expressions rather than just by type.

·       

The VB.NET part of
Visual Studio .NET compiles your code in the background. While this is
considered an advantage for small projects, people creating very large projects
have found that the IDE slows down considerably as the project gets larger.

 

C# Advantages

 

·       
XML documentation generated from source code
comments. (This is coming in VB.NET with Whidbey (the code name for the next
version of Visual Studio and .NET), and there are tools which will do it with
existing VB.NET code already.)

·       
Operator overloading – again, coming to VB.NET
in Whidbey.

·       
Language support for unsigned types (you can use
them from VB.NET, but they aren’t in the language itself). Again, support for
these is coming to VB.NET in Whidbey.

·       
The using statement, which makes unmanaged
resource disposal simple.

·       

Explicit interface implementation, where an
interface which is already implemented in a base class can be reimplemented
separately in a derived class. Arguably this makes the class harder to
understand, in the same way that member hiding normally does.

·       
Unsafe code. This allows pointer arithmetic etc,
and can improve performance in some situations. However, it is not to be used
lightly, as a lot of the normal safety of C# is lost (as the name implies).
Note that unsafe code is still managed code, i.e. it is compiled to IL, JITted,
and run within the CLR.

 

Despite the fact that the above
list appears to favor VB.NET (if you don’t mind waiting for Whidbey), many
people prefer C#’s terse syntax enough to make them use C# instead.

 

Also another factor that will
influence is your background in the Computer Field. If you are a hardcore C,
C++, VC++ programmer, you prefer taking C# as a language because the syntax is
more or less similar to what you wrote so far, where as if you are from a programmer who is more
accustomed to Basic, COBOL, VB, you tend
to go with VB.NET. If you are a fresher, as I said above "Learning the
.NET framework itself is a much bigger issue than learning either of the
languages, and it’s perfectly possible to become fluent in both – so don’t
worry too much about which to plump for.

 

 

Finally after all this general
talk, here are a few lines of applause for C#. Some of you may find it a little
biased but please bear with my views.

 

In retrospect, C# is my language
of choice for the .NET platform, What makes C# appealing to (a hardened C++ and
VB programmer) like me is the negligible learning curve, modern OO concepts and
built-in features for better coding. I can’t stress this enough, C# is a master
piece evolved from today’s most popular languages and has all the best features
borrowed (as you might say) from VB, C++ and Java.

 

Another interesting point is that
C# is better for newbie’s because it opens the doors for more languages (C/C++,
PERL, Java, and many more) and it’s easier to read.
