ArrayList / Thread / Reference Problem?

Ok, this is about a library that you probably do not know of, but just
follow with me.

I am having trouble disconnecting a client from an IRC Private
connection known as DCC. Knowlege of DCC isn't necessarily. I finally
realized the problem lies in my usage. The DCC Session is held within
a class which has a Close() method which invokes commands to close the
ports & the tcp listener's, etc.

Well i realized (i musta been tired.. well i still am :p) that
session.Close() does work, as i use it in a different section of code
and it works perfectly. I believe the reason 1 works and the other
doesn't is because the working one has the actual session. That is,
the user triggers an event, and as an argument, the event holds the
users session class. Then through a series of other classes which all
pass down the data, session.Close() is called. The users session is
just passed as an argument, not a reference object.

One possible thing to shed light on the subject is, how is this
argument passing (none reference) through functions different then an
ArrayList holding an object via the ArrayList.Add() method.

Because, as said, this function argument passing the session WORKS,
that is, calling session.Close() does exactly what it is supposed to,
however using a foreach loop to get each session out of the ArrayList
does no good as none of them have .Close() triggered.


I do not know all that much about threads and reference types, and
exactly what data is exchanged, but what is the reason for this?
session.SendMessage() (another function, which obviously, sends a
message) works fine from both the ArrayList and the
Function Argument Passing".. so, any idea what i could be doing wrong?
Aside from Events, the ArrayList is the only method i use to retrieve
the session's of Users.. and i know of no others..

My question revolves around my usage of the ArrayList mostly. I have
to be doing something wrong with it, or theres a fundemental flaw in
my usage...

Anyway, thanks to any replies!
