using System;
using System.Linq;
using System.IO;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
DirectoryInfo DirInfo = new DirectoryInfo(@"D:\Articles\Pics\jQuery");

DateTime dt1 = new DateTime(2009, 07, 15);
DateTime dt2 = new DateTime(2010, 04, 15);

// LINQ query for files between 15-July 2009 and 15-April 2010.
var files = from file in DirInfo.EnumerateFiles()
where file.CreationTimeUtc > dt1 &
file.CreationTimeUtc < dt2                       
select file;

// Show results.
foreach (var file in files)
{
Console.WriteLine("{0} created on {1}", file.Name, file.CreationTimeUtc);
}
Console.ReadLine();
