==Range Cartesian Join==

<source lang="csharp">using System;
using System.ruponentModel;
using System.Linq;
class MainClass
{
static void Main()
{
var query = from left in Enumerable.Range(1, 4)
from right in Enumerable.Range(11, left)
select new { Left = left, Right = right };
foreach (var pair in query)
{
Console.WriteLine("Left={0}; Right={1}", pair.Left, pair.Right);
}
}
}</source>

==Range Enumeration==

<source lang="csharp">using System;
using System.ruponentModel;
using System.Linq;
class MainClass
{
static void Main()
{
var collection = Enumerable.Range(0, 10);
foreach (var element in collection)
{
Console.WriteLine(element);
}
}
}</source>

==Range Filtering==

<source lang="csharp">using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ruponentModel;
class MainClass
{
static void Main()
{
var collection = Enumerable.Range(0, 10)
.Where(x => x % 2 != 0)
.Reverse();
foreach (var element in collection)
{
Console.WriteLine(element);
}
}
}</source>

==Range Ordering==

<source lang="csharp">using System;
using System.ruponentModel;
using System.Linq;
class MainClass
{
static void Main()
{
var collection = Enumerable.Range(-5, 11)
.Select(x => new { Original = x, Square = x * x })
.OrderBy(x => x.Square)
.ThenBy(x => x.Original);
foreach (var element in collection)
{
Console.WriteLine(element);
}
}
}</source>

==Range Projection==

<source lang="csharp">using System;
using System.ruponentModel;
using System.Linq;
class MainClass
{
static void Main()
{
var collection = Enumerable.Range(0, 10)
.Where(x => x % 2 != 0)
.Reverse()
.Select(x => new { Original = x, SquareRoot = Math.Sqrt(x) });
foreach (var element in collection)
{
Console.WriteLine("sqrt({0})={1}",
element.Original,
element.SquareRoot);
}
}
}</source>

==Range Reversal==

<source lang="csharp">using System;
using System.ruponentModel;
using System.Linq;
class MainClass
{
static void Main()
{
var collection = Enumerable.Range(0, 10).Reverse();
foreach (var element in collection)
{
Console.WriteLine(element);
}
}
}</source>
