使用Thread实现可以突破系统最小时间间隔的Timer

使用System.Timers.Timer和System.Threading.Timer创建的计时器会受系统最小时间间隔限制，在 Windows 系统中，默认的最小时间间隔为 15.6 毫秒（数据来自GPT）。Task.Run 方法来创建线程也会受此限制，故而使用Thread来进行实现，欢迎大家优化，代码如下：

public delegate void MyCallback();
class MyTimer
{
    public int Interval { get; set; } = 1000;
    private bool running = false;
    public event MyCallback Elapsed;
    private CancellationTokenSource cts;
    private Thread thread;

    public MyTimer()
    {
        cts = new CancellationTokenSource();
        thread = new Thread(ExecuteTimer);
        thread.Start();
    }

    private void ExecuteTimer()
    {
        Stopwatch sw = Stopwatch.StartNew();
        while (!cts.Token.IsCancellationRequested)
        {
            if (running && sw.ElapsedMilliseconds > Interval)
            {
                sw.Restart();
                Elapsed?.Invoke();
            }
            Thread.Sleep(1);
        }
    }

    public void Start()
    {
        running = true;
    }

    public void Stop()
    {
        running = false;
    }

    public void Close()
    {
        cts.Cancel();
        Elapsed = null;
        thread.Join(); // 等待线程结束
    }
}
