Чтение потока на поиск

[Kongor]

Доброго времени суток , есть поток который надо постоянно читать и вылавливать команду в виде слова на которое будет действие messegebox.show, за пример буду безмерно благодарен. Ниже листинг собственно куда мне нужно это воткнуть.

namespace ChatClient
{
    public partial class Form1 : Form
    {

        private string UserName = "Unknown";
        private StreamWriter swSender;
        private StreamReader srReceiver;
        private TcpClient tcpServer;

        private delegate void UpdateLogCallback(string strMessage);

        private delegate void CloseConnectionCallback(string strReason);
        private Thread thrMessaging;
        private IPAddress ipAddr;
        private bool Connected;

        public Form1()
        {

            Application.ApplicationExit += new EventHandler(OnApplicationExit);
            InitializeComponent();
        }


        public void OnApplicationExit(object sender, EventArgs e)
        {
            if (Connected == true)
            {

                Connected = false;
                swSender.Close();
                srReceiver.Close();
                tcpServer.Close();
            }
        }

            }
            else
            {

                string Reason = "Not Connected: ";

                Reason += ConResponse.Substring(2, ConResponse.Length - 2);

                this.Invoke(new CloseConnectionCallback(this.CloseConnection), new object[] { Reason });

                return;
            }

            while (Connected)

Привет, насколько я понимаю у тебя в листинге ответ на твой вопрос, просто в UpdateLog(string strMessage) нужно добавить
if(strMessage.Equals("Тут сообщение которое нужно показать")
{
MessageBox.Show(strMessage);
}
