ThenBy

Input:	IOrderedEnumerable<TSource>
Lambda expression:	TSource => TKey

Append a ThenBy operator:

 
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main()
    {
        string[] names = { "Java", "C#", "Javascript", "SQL", "Oracle", "Python", "C++", "C", "HTML", "CSS" };


        IEnumerable<string> query = names.OrderBy(s => s.Length).ThenBy(s => s);

        foreach (String s in query)
        {
           Console.WriteLine(s);
        }
    }
}

The output:


C
C#
C++
CSS
SQL
HTML
Java
Oracle
Python
Javascript

The following sorts first by length, then by the second character, and finally by the first character:


using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main()
    {
        string[] names = { "Java", "C#", "Javascript", "SQL", "Oracle", "Python", "C++", "C", "HTML", "CSS" };

        names.OrderBy(s => s.Length).ThenBy(s => s[1]).ThenBy(s => s[0]);

        foreach (String s in names)
        {
           Console.WriteLine(s);
        }
    }
}

The output:


Java
C#
Javascript
SQL
Oracle
Python
C++
C
HTML
CSS
