Copy of List<>


I am not sure how to fix this problem I've stumbled into...

I have a list<> of an interface type. I need to pass that list to a
method that adds more objects to the list.

But, eventually, I need to get back to the original list<> object.

---

In other words; let's say I start with an List<> of 3 objects. I call a
method that adds 5 more objects to that List<>. I continue on with my
work. Once I'm done, I need to get back to my original list of 3 objects.

My first guess is I to use a copy of my List object when I call the
appender method. But, I'm not sure how you can copy a List<> object.

Can't you just pass the original list you're cloning as an actual parameter
argument to the ctor?
List<string> workingNames = new List<string>(names);

That is awesome!

Yes that works! You saved me from doing a foreach... and adding the
elements one at a time into a new List.

Thanks a million!
