Copy Directory or Move folder in .NET

By Default, .NET doesn't provide any inbuilt method to copy directory/sub-directory or move folder as like XCopy command in DOS. Here is the method for this:

 private void XCopy(String src, String dest,Boolean isOverwrite)
    {
        DirectoryInfo currentDirectory;
        currentDirectory = new DirectoryInfo(src);
        if (!Directory.Exists(dest))
            Directory.CreateDirectory(dest);  
        foreach (FileInfo filein in currentDirectory.GetFiles())
        {
            filein.CopyTo(System.IO.Path.Combine(dest, filein.Name), true);
           // To move files uncomment following line
           // filein.Delete();
        } 
        foreach (DirectoryInfo dr in currentDirectory.GetDirectories())
        {
            XCopy(dr.FullName, Path.Combine(dest, dr.Name), isOverwrite); 
        }
    }
