- 딜레이 함수 만들기

private static DateTime Delay(int MS)
{
   DateTime ThisMoment = DateTime.Now;
   TimeSpan duration = new TimeSpan(0, 0, 0, 0, MS);
   DateTime AfterWards = ThisMoment.Add(duration);
 
   while (AfterWards >= ThisMoment)
   {
       System.Windows.Forms.Application.DoEvents();
       ThisMoment = DateTime.Now;
   }
 
   return DateTime.Now;
}

System.Threading.Thread.Sleep(자연수);
