            command.Connection.Open();
            command.ExecuteNonQuery();
        }
        catch (SqlException ex)
        {
            DisplaySqlErrors(ex);
        }
    }
}

private static void DisplaySqlErrors(SqlException exception)
{
    for (int i = 0; i < exception.Errors.Count; i++)
    {
        Console.WriteLine("Index #" + i + "\n" +
            "Error: " + exception.Errors[i].ToString() + "\n");
    }
    Console.ReadLine();
}

Public Sub ShowSqlException(ByVal connectionString As String)
    Dim queryString As String = "EXECUTE NonExistantStoredProcedure"

    Using connection As New SqlConnection(connectionString)

        Try
            command.Connection.Open()
            command.ExecuteNonQuery()

        Catch ex As SqlException
            DisplaySqlErrors(ex)
        End Try
    End Using
End Sub

Private Sub DisplaySqlErrors(ByVal exception As SqlException)
    Dim i As Integer

    For i = 0 To exception.Errors.Count - 1
        Console.WriteLine("Index #" & i & ControlChars.NewLine & _
            "Error: " & exception.Errors(i).ToString() & ControlChars.NewLine)
    Next i
    Console.ReadLine()
End Sub
