Voici une classe que j'utilise pour écrire des services. J'ai généralement un écran interactif qui s'affiche lorsque le service n'est pas appelé. À partir de là, j'utilise le cours si nécessaire. Il permet plusieurs instances nommées sur la même machine, par exemple le champ InstanceID.
Exemple d'appel
IntegratedServiceInstaller Inst = new IntegratedServiceInstaller();
Inst.Install("MySvc", "My Sample Service", "Service that executes something",
_InstanceID,
// System.ServiceProcess.ServiceAccount.LocalService, // this is more secure, but only available in XP and above and WS-2003 and above
System.ServiceProcess.ServiceAccount.LocalSystem, // this is required for WS-2000
System.ServiceProcess.ServiceStartMode.Automatic);
if (controller == null)
{
controller = new System.ServiceProcess.ServiceController(String.Format("MySvc_{0}", _InstanceID), ".");
}
if (controller.Status == System.ServiceProcess.ServiceControllerStatus.Running)
{
Start_Stop.Text = "Stop Service";
Start_Stop_Debugging.Enabled = false;
}
else
{
Start_Stop.Text = "Start Service";
Start_Stop_Debugging.Enabled = true;
}
