Question

Ho una copia funzionante del sito di asp.net mvc localmente. Ho appena caricato l'intero sito sul mio server di hosting web. tutto sembra a posto, ma quando effettuo il login, viene visualizzato il seguente errore:

System.ArgumentException: Parola chiave non supportata: 'provider'.

qualche suggerimento?

Answer 1

The value that was provided for the connection string may be wrong, or it may contain an invalid syntax.

Il mio suggerimento è quello di correggere la stringa di configurazione.

Answer 2

Questo MSDN article contiene tutti i valori di parola chiave consentiti all'interno dell'oggetto ConnectionString per SqlConnection. "Provider" non è nella lista.

Sono disponibili due opzioni:

• Rimuovi "provider" parola chiave;
• utilizzare un OleDbConnection invece di SqlConnection.

Answer 3

Rimuovere "Provider=MSDORA" dalla stringa di connessione. E poi questo dovrebbe funzionare.

Answer 4

anche Quando la connessione stringa di parametro "User ID" utilizzare lo spazio, se è scritto come "UserID" poi anche dà errore

Answer 5

orologio per parole chiave nel connectionstring che hanno bisogno di spazi. Come User ID è corretto ma UserID avrà esito negativo.
