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 CounterHelp prvního čítače se data předají konstruktoru, zatímco druhý čítač nastaví vlastnost explicitně.
