CompilerInfo
Esempio
Nell'esempio di codice seguente vengono visualizzate le impostazioni di configurazione del provider di linguaggio. Gli argomenti della riga di comando vengono usati per specificare una lingua, un'estensione del nome file o un tipo di provider. Per l'input specificato, l'esempio determina il provider di linguaggio corrispondente e visualizza le impostazioni del compilatore di linguaggio configurate.
// Command-line argument examples:
// - Displays Visual Basic, C#, and JScript compiler settings.
// <exe_name> Language CSharp
// - Displays the compiler settings for C#.
// <exe_name> All
// - Displays settings for all configured compilers.
// <exe_name> Config Pascal
// - Displays settings for configured Pascal language provider,
// if one exists.
// <exe_name> Extension .vb
// - Displays settings for the compiler associated with the .vb
// file extension.

Commenti
Usare la CompilerInfo classe per determinare se un'implementazione CodeDomProvider è configurata nel computer o per esaminare le impostazioni di configurazione e compilatore per un provider di linguaggio specifico.
L'elemento< system.codedom> nel file di configurazione del computer contiene le impostazioni di configurazione del provider di linguaggio e del compilatore. Ogni provider di linguaggio configurato ha un elemento di configurazione del compilatore corrispondente. Ogni elemento definisce il tipo di implementazione, i nomi del linguaggio supportati, le estensioni del nome file supportate e i parametri del CodeDomProvider compilatore.
.NET Framework definisce le impostazioni iniziali del compilatore nel file di configurazione del computer. Gli sviluppatori e i fornitori di compilatori possono aggiungere impostazioni di configurazione per una nuova implementazione di CodeDomProvider.
La CompilerInfo classe fornisce l'accesso in sola lettura a queste impostazioni nel file di configurazione del computer. Usare i GetLanguagesmembri , GetExtensionse CodeDomProviderType per esaminare gli attributi di configurazione corrispondenti per un provider di linguaggio. Usare il CreateDefaultCompilerParameters metodo per ottenere le opzioni del compilatore e i valori degli attributi a livello di avviso per un provider di linguaggio.
Per altre informazioni sulle impostazioni del provider di linguaggio nel file di configurazione, vedere Schema delle impostazioni del provider di linguaggio e del compilatore.
Nota
Questa classe contiene una richiesta di collegamento a livello di classe che si applica a tutti i membri. Viene SecurityException generato quando il chiamante immediato non dispone dell'autorizzazione di attendibilità completa. Per informazioni dettagliate sulle richieste di collegamento, vedere Richieste di collegamento.
