timer loop for reading csv file

Question

Hi wanna ask, is there any way to edit this code to make it as a timer. Because I want to get last edit csv file and save it to the database, at least loop for about 30 second.

 

foreach (FileInfo file in filess)

{
   DateTime lastWriteTime = file.LastWriteTime;
   Console.WriteLine("Time last Edit : " + lastWriteTime);

}

 

thank you
