This class is created whenever the .NET Framework Data Provider for OLE DB encounters an error generated from the server. (Client side errors are thrown as standard common language runtime exceptions.) OleDbException always contains at least one instance of OleDbError.
If the severity of the error is too great, the server may close the OleDbConnection. However, the user can reopen the connection and continue.
The following example generates an OleDbException because of a missing data source, and then displays the exception.
public void ShowOleDbException() { string mySelectQuery = "SELECT column1 FROM table1"; OleDbConnection myConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;DataSource="); OleDbCommand myCommand = new OleDbCommand(mySelectQuery,myConnection); try { myCommand.Connection.Open(); } catch (OleDbException e) { string errorMessages = ""; for (int i=0; i < e.Errors.Count; i++) { errorMessages += "Index #" + i + "\n" + "Message: " + e.Errors[i].Message + "\n" + "NativeError: " + e.Errors[i].NativeError + "\n" + "Source: " + e.Errors[i].Source + "\n" + "SQLState: " + e.Errors[i].SQLState + "\n"; } System.Diagnostics.EventLog log = new System.Diagnostics.EventLog(); log.Source = "My Application"; log.WriteEntry(errorMessages); Console.WriteLine("An exception occurred. Please contact your system administrator."); } }
