Question

I have two classes, as follows:

public class Route
{
    public ObservableCollection<Flight> Flights = new ObservableCollection<Flight>();
}

public class Flight
{
    string airlineName;
}

I wish to return a list of all routes that have a flight that is operated by a specified airline.

I tried doing Routes.SelectMany(x => x.Flights).Where(x => x.Airline == airline); but that returns all the flight objects – I need the route objects…

Can anyone explain how I can do this using ObjectQuery? Thanks in advance!

Answer 1

Routes.Where(x =>x.Flights.Any(p=> p.Airline == airline))
