Esempio

Questa sezione fornisce due esempi di codice. Il primo illustra come specificare in modo dichiarativo i valori per diverse proprietà della AssemblyCollection classe . Il secondo illustra come usare i membri della AssemblyCollection classe .

Nell'esempio di file di configurazione seguente viene illustrato come specificare in modo dichiarativo i valori per diverse proprietà della AssemblyCollection classe .
