Question

In c#, Given the following code:

public class Person
{
    public int PersonID { get; set; }
    public int Age { get; set; }
    public string Name { get; set; }
}

and

    List<Person> people = new List<Person>();

    for (int i = 0; i != 15; i++)
    {
        Person p = new Person();
        p.PersonID = i;
        p.Age = i * 12;
        p.Name = "Name " + i;
        people.Add(p);
    }


    var sortedPeople = from qPeople in people
                       where qPeople.Age > 0 && qPeople.Age < 25 || qPeople.Age > 100
                       orderby qPeople.Age descending
                       select qPeople;

Can I load the results of sortedPeople back into a List<Person> without a loop?

Thanks.

Answer 1

Yes. There is a .ToList() extension method available, so all you would need to do is make a call to it like this.

var sortedPeople = (from qPeople in people 
                       where qPeople.Age > 0 && qPeople.Age < 25 || qPeople.Age > 100 
                       orderby qPeople.Age descending 
                       select qPeople).ToList(); 

Now sortedPeople will be a List<Person> instead of an IOrderedEnumerable<Person>
