EventArrivedEventArgs Class

Definition

Holds event data for the EventArrived event.

C#
public class EventArrivedEventArgs : System.Management.ManagementEventArgs
Inheritance
EventArrivedEventArgs

Remarks

The following asynchronous example sets up a WMI timer to raise an event every second, and removes it when no longer needed. The ManagementEventWatcher defines several .NET Framework events which are raised when WMI events are delivered. Delegates are attached to these events for handling the incoming data.

C#
using System;
using System.Management;

// This example shows asynchronous consumption of events.
// In this example you are listening for timer events.
// The first part of the example sets up the timer.
public class EventWatcherAsync
{
    public EventWatcherAsync()
    {
        // Set up a timer to raise events every 1 second
        //=============================================
        ManagementClass timerClass =
            new ManagementClass("__IntervalTimerInstruction");
        ManagementObject timer = timerClass.CreateInstance();
        timer["TimerId"] = "Timer1";
        timer["IntervalBetweenEvents"] = 1000;
        timer.Put();

        // Set up the event consumer
        //==========================
        // Create event query to receive timer events
        WqlEventQuery query =
            new WqlEventQuery("__TimerEvent",
            "TimerId=\"Timer1\"");

        // Initialize an event watcher and
        // subscribe to timer events
        ManagementEventWatcher watcher =
            new ManagementEventWatcher(query);

        // Set up a listener for events
        watcher.EventArrived +=
            new EventArrivedEventHandler(
            this.HandleEvent);

        // Start listening
        watcher.Start();

        // Do something in the meantime
        System.Threading.Thread.Sleep(10000);

        // Stop listening
        watcher.Stop();
    }

    private void HandleEvent(object sender,
        EventArrivedEventArgs e)
    {
        Console.WriteLine("Event arrived !");
    }

    public static void Main(string[] args)
    {
        // start the event watcher
        EventWatcherAsync eventWatcher = new
            EventWatcherAsync();
    }
}
