Question

I need to check if a postcode is within a given start and end postcode, using linq.

Here is what I have so far but it’s not right at all, can someone point me in the right direction?

List<DestinationStation> stations = DestinationStation.GetDestinationStations();
var query = from s in stations
            where postcode <= s.FromPostcode && postcode >= s.ToPostcode
            select s;
Console.WriteLine(query.ToList());

Answer 1

Try CompareTo for strings. Does this work?

var query =
    from s in stations
    where postcode.CompareTo(s.FromPostcode) >= 0
    where postcode.CompareTo(s.ToPostcode) <= 1
    select s;
