Compare Vb.net and C#

[Prateek Sethi[GrapeCity]]

Hi,

Can somebody let me know the differences between vb.net and C# or point me
to an article? I do not need syntax and keyword differences, but an insight
on the funtionality diff. between the two languages/compilers.

Thanks

There are not much differences as functionality and
compilers.MS aim is Language independent. But vey minor
Diff.are exist like

1) we cann't write unmanaged code using VB but it is
possible with C#.

2)C# has XML Comments that allow you to stick XML into the
code to make it self-documenting. This isn't actually a
feature of C#, it's just that someone neglected VB.NET
when they put it in, but it is a smart feature to use when
you want to quickly document assemblies and applications.

3)VB gained >> and << bitwise operators in the latest
version, although it still can't work with unsigned types
so their usefulness is limited.

4)VB has optional parameters, C# doesn't
5)C# has operator overloading, VB doesn't
6)late binding implementation at VB is very easy compared
to C#.

No it's not. You can write *unsafe* code with C#, but it's still
managed. There's a big difference between unmanaged and unsafe.

Thanks a lot Sridhar!! This is a great help..

Thanks to all..

While on the same topic, I would like to give some background of this
question..

I have found that there is a difference in how C# and VB.NET compliers treat
overloaded methods in the derived class. While VB.NET looks for the best
fit, C# fits in the method call to the derived class member if that is
possible. Take a look at the two samples below. Run these and notice the
difference. I would be glad if you could throw some light on this or point
out if I am doing something wrong here.

Thanks,
Prateek
