我正在实现一种通信算法，以非常快地定期发送信息，即每包之间发送 1 毫秒。我有一个使用任务发送包的功能版本。这是我的代码示例:

private void Work()
{
    Stopwatch stopwatch = new Stopwatch();
    stopwatch.Start();

    while (!cancellationTokenSource.Token.IsCancellationRequested)
    {
        if (!Pack.PeriodicOn)
            cancellationTokenSource.Cancel();

        // Time used to send the packs before the interval time
        double tolerance = Pack.Interval * 0.2F;

        // In case of interval bigger than 25ms send pasks only 5ms before
        if (tolerance > 5) tolerance = 5;

        TimeSpan timeSpan = stopwatch.Elapsed;

        // The waiting time is controlled by the condition below, if the condition is false, the while loop continues execution         
        // Send the information a little bit before to interval time to deal with the transmision delay
        if (Pack.LastSent.TotalMilliseconds == 0 ||
             timeSpan.TotalMilliseconds - Pack.LastSent.TotalMilliseconds >=
             (Pack.Interval - tolerance))
        {
            SendData(Pack);
            Pack.LastSent = timeSpan;
        }
    }

    Pack.LastSent = new TimeSpan(0);
}
