we have the chance to develop in VB.Net (not in Java) and some variable's definitions can be shortened.

I still use GetFiles() and I have added the code to display the DateTime infos.

Imports System
Imports System.IO
...
Dim dir As New DirectoryInfo(sFolderName)
For Each f In dir.GetFiles()
    Console.WriteLine(">> FILE-NAME: [" & f.Name & "]")
    Console.WriteLine(">> UPDATE-DATE: " & f.lastWriteTime.toString("yyyy-MM-dd"))
    Console.WriteLine(">> CREATE-DATE: " & f.creationTime.toString("yyyy-MM-dd"))
Next

Use DirectoryInfo.GetFiles() and extract the data (Name, CreationTime, etc.) from the FileInfo class.

I've pasted some code from the MSDN page here.

Imports System
Imports System.IO
Public Class GetFilesTest
    Public Shared Sub Main()
        ' Make a reference to a directory.
        Dim di As New DirectoryInfo("c:\")
        ' Get a reference to each file in that directory.
        Dim fiArr As FileInfo() = di.GetFiles()
        ' Display the names of the files.
        Dim fri As FileInfo
        For Each fri In fiArr
            Console.WriteLine(fri.Name)
        Next fri
    End Sub 'Main
End Class 'GetFilesTest
