Another LINQ 101 question

[Mike P]

In the SelectManyIndexed example (see below), what syntax do you need to
actually write the results of the query to the screen?

var customerOrders =
customers.SelectMany(
(cust, custIndex) =>
cust.Orders.Select(o => "Customer #" + (custIndex + 1) +
" has an order with OrderID " +
o.OrderID));

In the SelectManyIndexed example (see below), what syntax do you need to
actually write the results of the query to the screen?

var customerOrders =
            customers.SelectMany(
                (cust, custIndex) =>
                cust.Orders.Select(o => "Customer #" + (custIndex + 1) +
                                        " has an order with OrderID " +
o.OrderID));

Just plain old foreach?

foreach (var o in customerOrders) Console.WriteLine(o);

You can of course remove customerOrders entirely, and move the entire
LINQ expression inside foreach(), though in this case it would
probably hamper readability.
