Find the item with the lowest value of a property within a list

Question

Let\'s say I have this class:

class Person {
   public int ID;
   public string Name;
}

And then I have a list of Person\'s.

Answer 1

Use the Min extension method of LINQ:

persons.Min(p => p.ID)

EDIT:

My bad, the previous method returns only the lowest ID, so in case you'd like to use only built-in LINQ methods, here you go:

persons.Aggregate(
    (personWithMinID, currentPerson) =>
        currentPerson.ID <= personWithMinID.ID ? currentPerson : personWithMinID)
