Should I be using SqlDataReader inside a “using” statement?

Question

Which of the following two examples are correct? (Or which one is better and should I use)

In the MSDN I found this:

private static void ReadOrderDat         


        

Answer 1

Would it not be simpler to use this code?

    private static void ReadOrderData(string connectionString)
    {
        string queryString =
            "SELECT OrderID, CustomerID FROM dbo.Orders;";

        using (SqlDataReader reader = SqlHelper.ExecuteReader(connectionString, CommandType.Text, queryString))
        {
            // Call Read before accessing data.
            while (reader.Read())
            {
                Console.WriteLine(String.Format("{0}, {1}",
                reader[0], reader[1]));
            }
        }
    }

This should dispose of the reader, and the implicit connection and command when the using is terminated.

Or have I missed something?
