in c# 2.0 will be possible use a new keywork "yield"...

I would like to know if there is an algorithm that implements yield
statement in a c# or c++

thanks

C# 2.0: supports yield (in an iterator)
C# < 2.0: no
C++: no
VB: no

In the languages without language-level iterator support, you'll need to
write the enumerator code by hand.

I know this...
I think that c# compiler translate the yield statement in an
enumerator!!! I would like to know how happen this!!! A translation
algorithm?

thank you Mickey

I know this answer won't help you much, but... I found an example completely
worked out in one of the PPT files from the PDC2003. I don't really remember
which one, though. You might be able to find it by using the session name.
 
It is implemented as an Enumerator because thats what it is and its
also backward compatible with lesser runtimes.
 
It converts the iterator into an implementation of IEnumerator or
IEnumerable, just as if you had written the code yourself (or better in some
cases :)
