Sort List<List<string>> by length in ascending order

Question

May I know how to sort List<List<string>> by the length of List<string> in ascending order?

Answer 1

var result = list.OrderBy(x => x.Length)

Answer 2

Have a look at the List<T>.Sort method:

listOfListOfStrings.Sort((a, b) => a.Length.CompareTo(b.Length));

Alternatively, you can create an IEnumerable<List<string>> from the List<List<string>> that returns the lists in sorted order when enumerated, but leaves the original list untouched:

IEnumerable<List<string>> result = listOfListOfStrings.OrderBy(x => x.Length);
