    You're sure it wasn't something like this?

    foreach (User user in users)
    {
    yield return user;
    }

    I think Luc may have been hinting at this - he'd better remember not to make such hints so subtle next time... "they probably will have introduced a new keyword yielding some attention to more recent customers..."

            I once saw a programmer write this. foreach (User user in users) { return user; } :laugh:

            I have seen this when the array doesn't contain a indexing property. return users[0]; // Doesn't work I seem to remember this being the default behaviour for non generic Lists in early .net (2?).

              I've seen that - and I've also done this "kludge" when I literally didn't have time to look it up: e.g. Must get done fast, bigger fish to fry.. this works - move on. Not ideal - but - depends what's going on.. schedule.. time constraints. It's still readable at least. --Jason

                  If, in fact, you are using .NET 3.5, as otherwise this doesn't exist.

                    If users provides only the IEnumerable interface then you kinda have to do that. We'd need to see more of the code to determine just how horrible it is.

                    Ouch, you sure stepped in the salad! That code necessarily returns the first item in enumerating "users". Had it been a yield return things would be different though.
