Boxing information / quiz

[J.Marsch]

Hello all:

I am trying to introduce the concept of boxing (and some of the hang-ups) to
some developers that are coming onto a project. A while back, I read a
really cool article that was formatted as a quiz. It introduced a number of
the weird little nuances that you run into when implicit boxing occurs in
your code (like values not being changed when you expected them to -- do to
the fact that a copy was made during the box or unbox operation).

I would love to share this article with some of the other people on the
project, but I don't seem to have it bookmarked anymore, and I can't find
it. Has anyone run across it (or a similar article)?

Funny you should ask. I saw that site today. Hopefully I'll remember your
question while I"m at work tomorrow and I can pull it from my history.

I can't believe I can't find it. I checked history on my laptop, home PC,
and work PC.. I had searched for information on boxing and unboxing int
arrays and even tried the search again.

Well, I wasn't much help but I'm sure you can find enough on boxing/unboxing
to teach it.

Is this the article you're looking for?

Thanks Mikeb. This helps a lot. I think that is the one that I was
thinking. Actually, now I'm thinking that maybe I was remembering two
different web pages. This one is definitely one of them. The other listed
some unexpected effects that you might get when you start trying to assign
values to boxed items -- the values would not seem to "stick" because you
are really manipulating a copy. I don't remember exactly how the examples
went, though.

Thanks for the page, though. I know that's what I was thinking of. Now I
just know that I was really after two pages <g>
