Esempio

Nell'esempio di codice seguente viene illustrato come ottenere e impostare la CounterHelp proprietà . In questo esempio vengono creati due contatori e viene impostata la relativa CounterHelp proprietà usando tecniche diverse. Quando il primo contatore viene inizializzato, i CounterHelp dati vengono passati al costruttore, mentre il secondo contatore imposta la proprietà in modo esplicito.
