List all Files in .NET 4.0 Based on the Creation Date

Tweet

I had recently posted on 7 New methods to Enumerate Directory and Files in .NET 4.0

A user commented asking if it was possible to returns a list of files from a directory for a given date range (i.e. start date - end date). Here’s how to do so:

C#

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();
}
}
}

VB.NET 10.0 (converted)

Namespace ConsoleApplication1
Friend Class Program
Shared Sub Main(ByVal args() As String)
Dim DirInfo As New DirectoryInfo("D:\Articles\Pics\jQuery")

Dim dt1 As New Date(2009, 07, 15)
Dim dt2 As New Date(2010, 04, 15)

' LINQ query for files between 15-July 2009 and 15-April 2010.
Dim files = From file In DirInfo.EnumerateFiles()
Where file.CreationTimeUtc > dt1 And file.CreationTimeUtc < dt2
Select file

' Show results.
For Each file In files
Console.WriteLine("{0} created on {1}", file.Name, file.CreationTimeUtc)
Next file
Console.ReadLine()
End Sub
End Class
End Namespace

OUTPUT
