Question

I have a CarData object with the following properties:
PrimaryKey Make Model Year Drivetrain Country

I have about 1000 of these CarData objects in a List :
List<CarData> CarObjects

Is there a simple way to get a list of the distinct Makes?

Answer 1

var makes = CarObjects.Select(car => car.Make).Distinct();

This transforms the list from a list of CarData to a list of Makes, and then just finds the distinct values of the new list.
