Question

Assume

class Person
{
string FirstName;
string LastName;
int Age;
}

and a list

List<Person> listPerson;

Possible ways to get a list of only first names of all the person in this list

Answer 1

I think your easiest way will be

List<string> firstNames = listPerson.Select(p => p.FirstName).ToList()

But in order to do this, you’ll need to make the properties public.
