Linq select objects in list where exists IN (A,B,C)

I have a list of orders.
I want to select orders based on a set of order statuses.

So essentially select orders where order.StatusCode in ("A", "B", "C")

// Filter the orders based on the order status
var filteredOrders = from order in orders.Order
                     where order.StatusCode.????????("A", "B", "C")
                     select order;
