LINQ - Restriction Operator 'where'

The .NET Framework 3.5 version extends the .NET Framework 2.0 and 3.0 versions. One of the new features is the Language-Integrated Query (LINQ) and this extends powerful query capabilities to the C# language syntax (and VB as well) in the form of standard easily-learned query patterns.

A very simple program that displays the odd digits in LINQ:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace TestLinQ

{

    class Program

    {

        static void Main(string[] args)

        {

           // declare an array of integers

           int[] digits = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };

           // find all odd digits

           var oddDigits = from n in digits where n % 2 == 1 select n;

           // display all odd digits

           foreach(var x in oddDigits)

           {

              Console.WriteLine(x);

           }

        }

    }

}

This is indeed my first LINQ experience ;-), more precisely with the restriction operation 'where' ...
