每秒C＃限制呼叫

Question

我正在呼叫僅允許10次呼叫的服務。 我正在使用Stopwatch和Thread.Sleep限制通話。 這些是該工作的正確工具，還是我應該使用計時器或其他工具？

     public void SomeFunction() {
        Stopwatch stopwatch = new Stopwatch();
        int numCallsThisSecond = 0;

        foreach(MyEvent changedEvent in changedEvents) {
            stopwatch.Start();

            service.ChangeEvent(changedEvent);

            numCallsThisSecond += 1;
            stopwatch.Stop();
            if(numCallsThisSecond==10 && stopwatch.ElapsedMilliseconds<=1000)
                Thread.Sleep((int)(1100-stopwatch.ElapsedMilliseconds));
            if(stopwatch.ElapsedMilliseconds>1000) {
                stopwatch.Reset();
                numCallsThisSecond = 0;
            }
        }
    }

預先感謝您的任何幫助！

如您所知，它可以是10個呼叫/秒。 代碼可以很簡單，如下所示：

    public void SomeFunction() 
    {
        foreach(MyEvent changedEvent in changedEvents) 
        {
            service.ChangeEvent(changedEvent);
            Thread.Sleep(100);//you already know it can be only 10 calls / sec
        }
    }

編輯：好的，請查看以下替代方法是否會有所幫助，它每秒僅允許10次或更少的呼叫，具體取決於其性能：

    public void SomeFunction() 
    {
        DateTime lastRunTime = DateTime.MinValue;

        foreach(MyEvent changedEvent in changedEvents) 
        {
            lastRunTime = DateTime.Now;
            for (int index = 0; index < 10; index++)
            {
                if (lastRunTime.Second == DateTime.Now.Second)
                {
                    service.ChangeEvent(changedEvent);
                }
                else
                {
                    break;//it took longer than 1 sec for 10 calls, so break for next second
                }
            }
        }
    }
