listing the files depends on file creation time

Question

At present i am retrieving the file names depends up on creation time of file ...

private void filteringFiles()
{
  string filenamepath = @"C:\defualt\Access\backupdb\";
  List<String> listfiles = Directory.GetFiles(@"C:\defualt\Access\backupdb\", "backup-*.zip").ToList();
  List<String> files = new List<String>();
  List<String> getfiles = new List<String>();
  foreach (var allfiles in listfiles)
  {

    files.Add(Path.GetFileName(allfiles));
    //DateTime creationtime = File.GetCreationTime(files);
  }
  if (cbbackupforms.Text == "Month")
  {
    getfiles = (from string s in files where (DateTime.Now.Day - Convert.ToInt32(File.GetCreationTime(Path.Combine(filenamepath, s)).AddDays(-30).Day) < 1) && ((DateTime.Now.Year - (File.GetCreationTime(Path.Combine(filenamepath, s))).Year) == 0) select s).ToList();

  }

  if (cbbackupforms.Text == "ALL")
  {
    getfiles = files.ToList();

  }

  listbox1.DataSource = getfiles;

I mean if i created file at this time ...that file will be on top of list ... (ascending order depends upon file creation time)
