Im fünften Teil meiner Serie möchte ich auf erweiterte Möglichkeiten der Konfiguration des Dienstes eingehen. Über die ApplicationSettings ist es in Visual Studio ganz einfach möglich Strings, Integer usw. als globale Anwendungseinstellungen (web.config bei ASP.NET – sonst app.config) abzuspeichern:<\/p>\n

\n

Der Zugriff auf die Einstellung “ServerName” erfolgt dann ganz einfach über Properties.Settings.Default.ServerName<\/em>. Man kann sogar zur Laufzeit die Settings ändern und wieder abspeichern.<\/p>\n
Wenn man jedoch komplexere Strukturen in den Einstellungen ablegen möchte, kommt man um etwas Code nicht mehr herum. Im folgenden Beispiel lege ich die neue Sektion “entrances” an, um dort dann beliebig viele Eingangsverzeichnisse überwachen zu lassen:<\/p>\n
