2023-04-18 C#: SuperTimer 20mS Count Implement

I have implement a SuperTimer class but it seems if I did not dispose it, it will accumate in memory event the object exit the suage function.

So, I rewrite it with dispose() implement as follows.

    public class SuperTimer : IDisposable
    {
        public System.Timers.Timer gTickTimer = new System.Timers.Timer(20);
        private UInt32 gTickCount;
        private UInt32 aStartTick;
        private UInt32 aDuration;
        private UInt32 aStopTick;
        // Constructor
        public SuperTimer()
        {
            gTickCount = 0;
            // Have the timer fire repeated events (true is the default)
            gTickTimer.AutoReset = true;
            // Hook up the Elapsed event for the timer. 
            gTickTimer.Elapsed += gTickTimer_Elapsed;
            // Start the timer
            gTickTimer.Enabled = true;
        }
        private void gTickTimer_Elapsed(Object source, System.Timers.ElapsedEventArgs e)
        {
            gTickCount += 1;
        }
        public void StartTimer(UInt32 inDurationMS)
        {
            aStartTick = gTickCount;
            aDuration = inDurationMS / 20; // 每20mS回Call一次
            aStopTick = aStartTick + aDuration;
        }

        public bool TimerExpired()
        {
            if ((aStopTick == 0) || (gTickCount >= aStopTick))
            {
                aStopTick = 0;
                return (true);
            }
            else
                return (false);
        }

        bool disposed;
        protected virtual void Dispose(bool disposing)
        {
            if (!disposed)
            {
                if (disposing)
                {
                    //dispose managed resources
                }
            }
            //dispose unmanaged resources
            disposed = true;
        }
        public void Dispose()
        {
            gTickTimer.Stop();
            gTickTimer.Dispose();
            Dispose(true);
            GC.SuppressFinalize(this);
        }
    }
