推荐答案

尝试: ... Random r = new Random(); int questionNumber = r.Next(0, numberOfQuestions); AskQuestion(questionNumber); Timer t = new Timer(); t.Interval = 10000; // 10 seconds t.Elapsed+=new ElapsedEventHandler(OnTimedEvent); t.Start(); ... private static void OnTimedEvent(object source, ElapsedEventArgs e) { Timer t = source as Timer; if (t != null) { t.Stop(); } FailedToAnswerInTime(); }

有一些细节，例如将Random对象保留为类的一部分，以确保每次都不相同，确保您在一次会话中不会问相同的问题，等等.思想.

There are some details, like keeping the Random object as part of your class to ensure it is different each time, making sure you don''t ask teh same question twice in a session, etc. But those you can handle with a bit of thought.
