Do you have a simple example for creating a simple hello
world compiler in c# or vb.net?
thanks

Are you trying to write your own compiler using VB or C#
or to compile a "Hello World" application using the .Net
language compilers? If you want to compile a hello world
app, use csc.exe or vbc.exe off the command line as
follows:
csc MyCodeFile.cs
if the default flags do not create what you want, use
csc /? to see the available options.

If instead you want to write your own compiler, (assuming
you have a good understanding of compiler construction)
the book: Compiling for the .Net Common Language Runtime
(CLR) by John Gough ISBN 013062296-6 is a good source on
MSIL and the code generation phases for CLR compatible
languages.

Your own compiler for your own language? Why?

Of course! I think of switching from C# to Sebastian.Net!

The first step in writing a compiler is to write a parser. You can find a
parser generator (that emits C# code) at
http://www.nongnu.org/grammatica/index.html. That will allow you to define
your source language.

Then you will have to generate executable code from the parse tree. To do
that you need to know the target instruction set. You should consider
targeting the dotNet intermediate language. That way you can get DotNet to
generate the actual code for you. Or, you could have your compiler emit C#
code which you would then compile with the dotNet C# compiler. Or, you
could have the parser execute the parse tree directly, via some sort of
interpreter.

Compilers are a large subject and there are many books on how to write them.
You should probably review one before proceeding.
