uses a compound orderby to sort a list of digits first by length of their name, and then alphabetically.

using System.Text;

public class MainClass {
    public static void Main() {

        string[] digits = { "zero", "one", "two", "three"};

        var sortedDigits =
            from d in digits
            orderby d.Length, d
            select d;

        Console.WriteLine("Sorted digits:");
        foreach (var d in sortedDigits) {
            Console.WriteLine(d);
        }
    }
}
