Public ReadOnly Property BaseDirectory As String

Valore della proprietà

String

Directory di base usata dal resolver dell'assembly per verificare la presenza di assembly.

Implementazioni

BaseDirectory

Eccezioni

AppDomainUnloadedException

L'operazione viene tentata in un dominio dell'applicazione non caricato.

Esempio

Nell'esempio di codice seguente viene creato un nuovo dominio applicazione, specificando una directory di base da usare durante la ricerca di assembly da caricare nel dominio. Nell'esempio viene quindi usata la BaseDirectory proprietà per ottenere il percorso della directory di base, per la visualizzazione nella console.
