        // Get the file contents of the directory to copy.
        FileInfo[] files = dir.GetFiles();

                // Copy the subdirectories.
                DirectoryCopy(subdir.FullName, temppath, copySubDirs);

        string path = @"C:\TEXTFILES\";
        string path2 = @"P:\myNetworkPath\tesssst";

        try
        {
            Directory.CreateDirectory(path2);

            foreach (string fileName in Directory.GetFiles(path))
            {
                File.Copy(
                    Path.Combine(path, fileName),
                    Path.Combine(path2, fileName), true);
            }
        }
        catch
        {
            Console.WriteLine("Exception");
        }

private void copyDirectory(string strSource, string strDestination)
{
    if (!Directory.Exists(strDestination))
    {
        Directory.CreateDirectory(strDestination);
    }

    DirectoryInfo dirInfo = new DirectoryInfo(strSource);
    FileInfo[] files = dirInfo.GetFiles();
    foreach(FileInfo tempfile in files )
    {
        tempfile.CopyTo(Path.Combine(strDestination,tempfile.Name));
    }

    DirectoryInfo[] directories = dirInfo.GetDirectories();
    foreach(DirectoryInfo tempdir in directories)
    {
        copyDirectory(Path.Combine(strSource, tempdir.Name), Path.Combine(strDestination, tempdir.Name));
    }
