Creating a List off of one of List

Question

So I have a list of Car objects.

List<Car> cars = GetCars();

I want to create a list of strings that come from the Car.Name string property.

I could do this:

List<string> carNames = new List<string>();
foreach(Car car in cars)
{
    carNames.Add(car.Name);
}

Is there a more fancy way to do this? Can you do this using LINQ?

Yes try `cars.Select(x=>x.Name).ToList();` You should have atleast googled it first before coming here. — Mahesh, Mar 25 '15 at 17:32

If you like a query expression syntax following works too:

var carNames = 
  (from c in cars
   select c.Name).ToList();

But.. Its not Lambda-expression. This is query-syntax, which will be converted by compiler to fluent-syntax which contains lambda-expressions. – Szer Mar 25 '15 at 17:37
You mean if you DON'T like lambda? – Rufus L Mar 25 '15 at 17:38
I meant Query syntax whereas the other answers are using method syntax. Both work. – Philip Stuyck Mar 25 '15 at 17:42

This will return only First element of car names. Or Default. – Szer Mar 25 '15 at 17:41
