It’s simple to get all file's names from the directory using the DirectoryInfo class and get the all files from that directory in dot.net. we have to set for Subdirectory if there are subdirectory is there than it will not check for subdirectory it will count from the root directory only and return the file name from that root directory.

{
  if (!IsPostBack)
  {
    DirectoryInfo d = new DirectoryInfo(Server.MapPath("~/FileToRead/"));
    string d2 = d.FullName.ToString();
    List<string> Files = Directory.GetFiles(d2, "*", SearchOption.AllDirectories).ToList();
    foreach (List<string> li in Files)
    {
      Response.Write(Files[0].ToString());
    }
