Multiple “order by” in LINQ

I have a list of orders and I need to order it by the date of the order and then a secondary sort by the price of the order. I'm not sure how exactly to do this since I tried orders.OrderBy(o => o.Date).OrderBy(o => o.Price), but it doesn't work. Any help is much appreciated. Thank you

Answer 1

You want to use the ThenBy function:

orders.OrderBy(o => o.Date).ThenBy(o => o.Price)

Answer 2

The other option is to use the LINQ query syntax instead of the method syntax:

 List<Order> sortedOrders = from o in orders
 orderby o.Date, O.Price
 select o;

Answer 3

You can use:

orders.OrderBy(o => o.Date).ThenBy(o => o.Price)
