Visual Studio 2008 - LINQ Ordering Operators Sample

OrderBy - Simple
This sample prints an alphabetically sorted version of an input string array. The sample uses orderby to perform the sort.
publicvoid Linqsample()
{
string[] colors = { "Blue", "red", "green" };
var sortedcolorss = from c in colors
orderby c
select c;
Console.WriteLine("The sorted list of colors:");
foreach (var c in sortedcolors)
{
Console.WriteLine(c);
}
}
Result
The sorted list of words:
Blue
green
red

Visual Studio 2008 - LINQ Restriction Operators Sample

Where - Simple 1
This sample prints each element of an input integer array whose value is less than 500. The sample uses a query expression to create a new sequence of integers and then iterates over each element in the sequence, printing its value.

public void LinqSample()
{
int[] arr= { 500, 400, 100, 300, 900, 800, 600, 700, 200, 000 };
var lowNums = from result in arr
where result < 500
select result ;
Console.WriteLine("arr < 500:");
foreach (var n in lowNums)
{
Console.WriteLine(n);
}
}
Result:
arr < 500:
400
100
300
200
000

Visual Studio 2008 - LINQ Partitioning Operators Sample

Partitioning Operators

Take - Simple

This sample uses Take to generate a sequence of the first three elements of an integer array. It then iterates through the sequence to print the results.
public void LinqSample()
{
int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };
var first3Numbers = numbers.Take(3);
Console.WriteLine("First 3 numbers:");
foreach (var n in first3Numbers)
{
Console.WriteLine(n);
}
}
ResultFirst 3 numbers:
5
4
1
