Beispiel

Im folgenden Beispiel wird mithilfe der ServiceController-Klasse überprüft, ob der Warndienst beendet wurde. Im Beispiel wird der Dienst gestartet, sofern er beendet wurde, und es wird gewartet, bis der Dienststatus auf Running festgelegt ist.

' Check whether the Alerter service is started.

Dim sc As New ServiceController()
sc.ServiceName = "Alerter"
Console.WriteLine("The Alerter service status is currently set to {0}", sc.Status)

If sc.Status = ServiceControllerStatus.Stopped Then
   ' Start the service if the current status is stopped.
   Console.WriteLine("Starting the Alerter service...")

   Try
      ' Start the service, and wait until its status is "Running".
      sc.Start()
      sc.WaitForStatus(ServiceControllerStatus.Running)
      
      ' Display the current service status.
      Console.WriteLine("The Alerter service status is now set to {0}.", sc.Status)
   Catch 
      Console.WriteLine("Could not start the Alerter service.")
   End Try
End If

// Check whether the Alerter service is started.
