List<T> OrderBy Alphabetical Order
If you mean an in-place sort (i.e. the list is updated):
people.Sort((x, y) => string.Compare(x.LastName, y.LastName));
If you mean a new list:
var newList = people.OrderBy(x=>x.LastName).ToList(); // ToList optional
Do you need the list to be sorted in place, or just an ordered sequence of the contents of the list? The latter is easier:
var peopleInOrder = people.OrderBy(person => person.LastName);
To sort in place, you'd need an IComparer<Person>
or a Comparison<Person>
. For that, you may wish to consider ProjectionComparer
in MiscUtil.
(I know I keep bringing MiscUtil up - it just keeps being relevant...)
people.OrderBy(person => person.lastname).ToList();
