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

this is without sorting the list and just iterates the list once.

Person minIdPerson = persons[0];
foreach (var person in persons)
{
    if (person.ID < minIdPerson.ID)
        minIdPerson = person;
}
