The select operator can accept an integer argument as an indexer.
This works only with local queries:
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.Select((s, i) => i + "=" + s);
foreach(String s in query){
Console.WriteLine(s);
}
}
}
The output:
0=Java
1=C#
2=Javascript
3=SQL
4=Oracle
5=Python
6=C++
7=C
8=HTML
9=CSS
