Commenti
CompilerError rappresenta un errore del compilatore o un avviso restituito dal compilatore.
Nota
Questa classe contiene una richiesta di ereditarietà a livello di classe che si applica a tutti i membri. Viene SecurityException generata un'eccezione quando la classe derivata non dispone dell'autorizzazione di attendibilità totale. Per informazioni dettagliate sulle richieste di ereditarietà, vedere Richieste di ereditarietà.
Costruttori
CompilerError() |
Inizializza una nuova istanza della classe CompilerError. |
CompilerError(String, Int32, Int32, String, String) |
Inizializza una nuova istanza della classe CompilerError utilizzando il nome file, la riga, la colonna, il numero e il testo di errore specificati. |
Proprietà
Column |
Ottiene o imposta il numero della colonna in cui è stato generato l'errore. |
ErrorNumber |
Ottiene o imposta il numero di errore. |
ErrorText |
Ottiene o imposta il testo del messaggio di errore. |
FileName |
Ottiene o imposta il nome del file di origine in cui è contenuto il codice che ha causato l'errore. |
IsWarning |
Ottiene o imposta un valore che indica se l'errore corrisponde a un avviso. |
Line |
Ottiene o imposta il numero di riga in cui è stato generato l'errore. |
Metodi
Equals(Object) |
Determina se l'oggetto specificato è uguale all'oggetto corrente. (Ereditato da Object) |
GetHashCode() |
Funge da funzione hash predefinita. (Ereditato da Object) |
GetType() |
