Question

Ich versuche, meine Website auf dem Remoteserver zu veröffentlichen. Mein Hosting-Provider hat mir dsn-Konnektivität über Dotnetpanel zur Verfügung gestellt. Wenn ich meine Seite veröffentliche, erhalte ich den Fehler wie im Screenshot gezeigt. Ich habe auch meine Datei web.config aufgenommen.

Meine web.config ist wie folgt,

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

Aus dem Stack-Trace es sieht aus wie Sie ein SqlClient.SqlConnection Objekt verwenden, aber DSN ist für ODBC-Verbindungen.

Sie ändern entweder Ihre Verbindungszeichenfolge, um eine SQL Server-Verbindungszeichenfolge zu verwenden, oder Sie ändern das Verbindungsobjekt in Ihrem Code zu ODBCConnection.

Answer 2

Eine große Sammlung gültiger Verbindungszeichenfolgenbeispiele für die verschiedenen Datenbanken und Technologien finden Sie unter connection strings website.
