also schon mal danke 🙂
aber bei uns klappt das irgendwie nicht....ich glaube das liegt daran, dass wir visual j# benutzen....
bei uns sieht der Quelltext folgendermaßen aus: (also der schon vom Programm her, vorgegebene Quelltext), das einzige, was wir hinzugefügt haben ist das mit dem double...

und wenn ich da jetzt irgendwo, private oder public hinzufüge, bekomme ich ne Fehlermeldung: "Unexpected private/public", "Syntax error" ....
Wir haben schon sooo vieles ausprobiert und nichts klapppttt ! Vor allem int erkennt dieses Programm komischerweise nicht bzw. erscheinen immer wieder Fehlermeldungen.
