Copy directory with only specific extension files

AFAIK, there's no method in the .NET Framework or the VB runtime library which can do this 'out of the box'. We'll therefore need to write a custom method:

using System;

using System.IO;

class Test

{

static void Main()

{

string sourceDir = "c:\\whatever";

string destDir = "c:\\whatever2";

CopyDirectory(sourceDir, destDir, "xls");

}

static void CopyDirectory(string sourceDir, string destDir, string extension)

{

string[] filePaths = Directory.GetFiles(sourceDir, "*." + extension);

if (!Directory.Exists(destDir))

{

Directory.CreateDirectory(destDir);

}

foreach(string filePath in filePaths)

{

string fileName = Path.GetFileName(filePath);

File.Copy(filePath, String.Format("{0}\\{1}", destDir, fileName));

}
