Adding String to a List - Quicker way?

Is there a quicker or more efficient way to add Strings to a List than the below example?:

List<String> apptList = new List<String>();

foreach (Appointment appointment in appointments){

    String subject = appointment.Subject;
    //...(continues for another 10 lines)

    //...And then manually adding each String to the List:   
    apptList.Add(subject);
    //...(continues for another 10 lines)

    //And then send off List apptList to another method
}

How about this:

List<string> apptList = appointments.Select(x => x.Subject).ToList();

I'm not sure if I'm getting your code right, but since your Appointment class is already implementing IEnumerable, you should be able to call ToList() to convert it to a list in one shot.
