(Part 2) Retriving data from a irc server

[Dumpen]

Hello.

Well since my last topic (http://www.codeguru.com/forum/showthread.php?p=1763094#post1763094) I have read quite a bit about threads, and I feel like I know it know, but I still have one question regarding data from a irc server.

I dont feel like running a while in my thread since it doesnt seem to be very stable, what other methods is recommended or is threadding the only way?

Here is what I got so far:
#region Variables
Thread addItemThread = null;
delegate void addItemDelegate();

TcpClient irc;

NetworkStream stream;
StreamReader reader;
StreamWriter writer;
#endregion

// Opdater list boks via invoke og en delegate
public void updateListBox()
{
while (reader.ReadLine() != null)
{
Invoke(new addItemDelegate(addItemToListBox));
}
}

// Sæt reader.Readline i listbox
public void addItemToListBox()
{
listBoxConsole.Items.Add(reader.ReadLine());
}

public void connect(string server, int port)
{
irc = new TcpClient(server, port);

stream = irc.GetStream();
reader = new StreamReader(stream);
writer = new StreamWriter(stream);

writer.WriteLine("USER CSharpBot 8 * :I'm a C# irc bot");
writer.Flush();
writer.WriteLine("NICK csharp12");
writer.Flush();
writer.WriteLine("JOIN #testchannel");
writer.Flush();
}

private void btnConnect_Click(object sender, System.EventArgs e)
{
connect("irc.chatcafe.net", 6667);

addItemThread = new Thread(new ThreadStart(updateListBox));
addItemThread.Start();
}

The most important lines are at:
while (reader.ReadLine() != null)
{
Invoke(new addItemDelegate(addItemToListBox));
}

Any help appreciated
