dumb remove question

[news]

Well here's a sample of the code:

class someobject{};
ArrayList alist;

alist = new ArrayList();

for(int i = 0; i<10;++i)
alist.Add(new someobject());




OK now how do I get rid of the 10 objects in alist?

Does Remove remove the object and delete it. Or does it just remeove it from
the list?

If it doesn't, how do I delete the objects?


Thanks,
Bill

..Remove removes the object from the list.
You don't need to delete the object, as long as you don't have any other
references to that object the GC will get around to deleting it at some
point.

alist.Clear();

Does Remove remove the object and delete it. Or does it just remeove it from
the list?

Just remove it from the list. Note that the object itself isn't in the
list - just a reference to the object.

If it doesn't, how do I delete the objects?

Why do you want to delete the objects in the first place? That's what
the garbage collector is for.
