Examples

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.");
   }
}
Public Sub ShowOleDbException()
    Dim mySelectQuery As String = "SELECT column1 FROM table1"
    Dim myConnection As New OleDbConnection _
       ("Provider=Microsoft.Jet.OLEDB.4.0;DataSource=")
    Dim myCommand As New OleDbCommand(mySelectQuery, myConnection)

    Try
        myCommand.Connection.Open()
    Catch e As OleDbException
        Dim errorMessages As String
        Dim i As Integer

        For i = 0 To e.Errors.Count - 1
            errorMessages += "Index #" & i.ToString() & ControlChars.Cr _
                           & "Message: " & e.Errors(i).Message & ControlChars.Cr _
                           & "NativeError: " & e.Errors(i).NativeError & ControlChars.Cr _
                           & "Source: " & e.Errors(i).Source & ControlChars.Cr _
                           & "SQLState: " & e.Errors(i).SQLState & ControlChars.Cr
        Next i

       Dim log As System.Diagnostics.EventLog = New System.Diagnostics.EventLog()
       log.Source = "My Application"
       log.WriteEntry(errorMessages)
       Console.WriteLine("An exception occurred. Please contact your system administrator.")
    End Try
End Sub

Remarks

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.

For general information about handling exceptions for a .NET Framework data provider, see SqlException.
