Examples

The following example displays the properties of the OleDbError.

public void DisplayOleDbErrorCollection(OleDbException exception)
{
    for (int i = 0; i < exception.Errors.Count; i++)
    {
        Console.WriteLine("Index #" + i + "\n" +
            "Message: " + exception.Errors[i].Message + "\n" +
            "Native: " + exception.Errors[i].NativeError.ToString() + "\n" +
            "Source: " + exception.Errors[i].Source + "\n" +
            "SQL: " + exception.Errors[i].SQLState + "\n");
    }
    Console.ReadLine();
}

Public Sub DisplayOleDbErrorCollection(ByVal exception As OleDbException)
    Dim i As Integer

    For i = 0 To exception.Errors.Count - 1
        Console.WriteLine("Index #" & i.ToString() & ControlChars.Cr _
           & "Message: " & exception.Errors(i).Message & ControlChars.Cr _
           & "Native: " & exception.Errors(i).NativeError.ToString() & ControlChars.Cr _
           & "Source: " & exception.Errors(i).Source & ControlChars.Cr _
           & "SQL: " & exception.Errors(i).SQLState & ControlChars.Cr)
    Next i
    Console.ReadLine()
End Sub

Remarks

This class is created by the OleDb data adapter when an error occurs. An instance of OleDbError is created and managed by the OleDbErrorCollection class, which in turn is created by the OleDbException class.

If the severity of the error is too great, the server may close the OleDbConnection. However, the user can reopen the connection and continue.
