Input: IOrderedEnumerable
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 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
