method argument names

I'm looking to get method argument names with reflection or any other way
..for ex:

public String getAddress(String name, int age)

I'd like to get the argument names "name" and "age".

Is this possible ...? and if yes, how ?

regards,
Chez

No.

Just of curiosity: Why do you want that?

Ciao,

Yes, its possible and some webservice frameworks ( like XFire and Axis
) do it. But it can only be done if your class i compiled with debug
info ( don't works on interfaces as i remember , only only on classes )

Still means "no" for reflection but "yes" for the debugger API.

Not easily, but I would suggest finding some way other than reflection
if possible. Reflection is often abused by people who have experience
with function pointers in C. There are likely other, better ways to do
what you intend.

If you let is know WHY you want to do it, we might be able to suggest a
better alternative.

Good luck.

Well, if the compiler has completely remove the name info (in the case
of non-debug output), then there's no way to get it back.

Hence, the not easily.

It would be possible if debug output was enabled, or if they used some
other technique to save the parameter names. The point of my post was
that the OP might be trying to do something that could be done another
simpler way.
