Esempio

Nell'esempio di codice seguente viene creato un oggetto XMLTask. Usando la Properties raccolta, vengono impostate le proprietà dell'attività. L'uso della Properties raccolta è il modo consigliato per impostare le proprietà in qualsiasi attività. Non è consigliabile eseguire direttamente il cast dell'attività nella classe e nelle proprietà equivalenti.
