    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();
    }

    static private string GetConnectionString()
    {
        // To avoid storing the connection string in your code, 
        // you can retrieve it from a configuration file.
        return "Data Source=(local);Initial Catalog=AdventureWorks;"
            + "Integrated Security=SSPI";
    }
}
