Answer / sherin

Differences are
1. Difference in Syntax
2. In some oops concepts

Answer / chandramouleswar

No difference is there when you are using VB.NET OR C3.NET
as the Code is compiled to IL. Both show equal performance
when it comes to the development.

Answer / vara prasad

In c# by default Option strict is on where as in vb.net
Option strict is off.

Answer / mohammad shahid ullah

VB.NET use the Not keyword to express logical negation.
C#.NET use the ! operator to express logical negation.

VB.NET statements are continued using the underscore(_).
C#.NET statements continue until the semiclone(;).

VB.NET

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


C#

* 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
re-implemented 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.

Answer / arash

I worked with both of them, I was comfortable with C# and when i introduced to VB.Net I don't wanna change it
its easy to write
neat and clean. trust me on this.

Answer / ajay

no difference between both two languages.both are generate
CIL code.just difference is syntax.in c#.net syntax is like
a our traditional languages c,c++,etc.but vb.net syntex is
differnt.

Answer / madhu

1)c# is case sensitive vb.net its not space sensitve
2)in vb.net abstract classes using "mustinherit" keyword,c#
we have "abstract" key word

3)vb.net has with construct which is not use in c#
4) c# allows pointers it can improve performence in some
situations.







note:Both use same frame work and spped is also very much
equalents.
