Esempio

In questa sezione vengono forniti due esempi di codice. La prima illustra come specificare in modo dichiarativo i valori per diverse proprietà della BuildProviderCollection classe . Il secondo illustra come usare i membri della BuildProviderCollection classe .

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

Commenti

Viene BuildProviderCollection usato per compilare file di risorse personalizzati. È possibile avere un numero qualsiasi di provider di compilazione. Non BuildProviderCollection fa riferimento ad alcun elemento effettivo nel file di configurazione sottostante. Si tratta di un costrutto che consente di accedere facilmente alle informazioni di compilazione contenute.
