我对这项任务有疑问。我不知道如何纠正它。谢谢您的帮助。
在这里，我为您创建了
Timer要使用计时器，请编写：
Timer timer = new Timer("Some Name", 100, TimeSpan.FromSeconds(1));
timer.Started += OnTimerStarted;
timer.Tick += OnTimerTick;
timer.Stopped += OnTimerStopped;
timer.Start();
private void OnTimerStarted()
{
}
private void OnTimerTick()
{
}
private void OnTimerStopped()
{
}
或
Timer timer = new Timer("Some Name", 100, TimeSpan.FromSeconds(1), OnTimerStarted, OnTimerTick, OnTimerStopped); // This one will start timer immediately
或
Timer timer = Timer.Run("Some Name", 100, TimeSpan.FromSeconds(1), OnTimerStarted, OnTimerTick, OnTimerStopped); // This one will start timer immediately

同样的任务？你设法解决它了吗？我现在真的需要帮助..
