Příklady

Následující příklad kódu ukazuje, jak získat a nastavit CounterHelp vlastnost. Tento příklad vytvoří dva čítače a nastaví jejich CounterHelp vlastnost pomocí různých technik. Při inicializaci prvního čítače CounterHelp jsou data předána konstruktoru, zatímco druhý čítač nastaví vlastnost explicitně.
