Something like this:

var persons = (from n in names()
               let s = n.split('~')
               select new Person { Name=s[1], Age=int.Parse(s[0]) }
              ).ToList();

var persons = names.Select(n => n.Split('~'))
                   .Select(a => new Person { Age=int.Parse(a[0]), Name=a[1] })
                   .ToList();

Essentially the same as Marcelo's answer.

Assuming that the source data are completely valid (i.e. no negative ages, names do not contain '~', every line has both age and name, and so on), here's a very easy implementation:

List<Person> persons = new List<Person>;

foreach (var s in names()) {
    var split = s.Split('~');
    int age = int.Parse (split[0]);
    string name = split[1];
    var p = new Person() { Age = age, Name = name };
    persons.Add (p);
}

You can also use a Linq query, which is shorter. See Marcelo's Answer for an example.
