Esempio

In questa sezione vengono forniti due esempi di codice. La prima 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 .
