Detailed explanation of the use of timers in C# and the application of automatic memory cleaning in schedule

The project is larger and sometimes it is more stuck. Although there is a GC automatic cleaning mechanism, there are still some unsatisfactory aspects. So try to manually write a timer in the project startup file to clean the memory regularly and speed up the project running.

public class Program
  {
    [DllImport("")]
    static extern int EmptyWorkingSet(IntPtr hwProc); //Cleaning memory related   static void Main()
    {
      //Cleaning memory timed      SetTimer();
    }
       /// <summary>
    /// Clean the memory regularly    /// </summary>
    private static void SetTimer()
    {
       aTimer = new (); //Initialize the timer       = 60000;//Configuration time 1 minute       += new (OnTimedEvent);
       = true;//Elapsed whenever the Elapsed event is reached       = true; //Indicates whether the Timer should raise an Elapsed event.    }
//Timer triggered processing eventprivate static void OnTimedEvent(Object source, ElapsedEventArgs e)
    {
      //Clean the memory      ();
      ();
      Process[] processes = ();
      foreach (Process process in processes)
      {
        //The following system processes do not have permissions, so skip them to prevent errors from affecting efficiency.        if (( == "System") && ( == "Idle"))
          continue;
        try
        {
          EmptyWorkingSet();
        }
        catch
        {
        }
      }
    }
}
