C#windows应用程序

最好的方法是使用事件处理程序作为发布者-订阅者范例。 在您使用的发布服务器中 public event EventHandler FlightStarted; 还有一个EventArgs类:

    public class StartEventArgs: EventArgs
    {
    public String flightCode { get; private set; }

    public StartEventArgs(String flightCode)
    {
        this.flightCode = flightCode;
    }

    public void OnFlightStarted(StartEventArgs e)
    {
        if (FlightStarted != null)
            FlightStarted(this, e);
    }

flight.FlightStarted += new EventHandler(flight_FlightStarted);

方法呢

    void flight_FlightLanded(object sender, EventArgs e)
    {
        if (e is LandEventArgs)
        {
            LandEventArgs landEventArgs = e as LandEventArgs;
            String flight = landEventArgs.flightCode;
            while (flight.Length <= 15)
                flight += " ";
            String time = DateTime.Now.ToLongTimeString();
            lbxStatus.Items.Insert(0, flight + "landed" 
                + "                 " + time);
        }
    }
