C# 任务、线程、同步（四）

Timer 类使用

  static void Main(string[] args)
         {
             ThreadingTimer();
             TimersTimer();

             Console.Read();
         }
         static void ThreadingTimer()
         {
            using( var t1 = new System.Threading.Timer(TimeAction, null, TimeSpan.FromSeconds(3), TimeSpan.FromSeconds(5)))
            {
                Thread.Sleep(20000);
                t1.Dispose();
            }
         }
         static void TimersTimer()
         {
             var t1 = new System.Timers.Timer(1000);
             t1.AutoReset = true;
             t1.Elapsed += (s, e) => { Console.WriteLine("System.Timers.Timer {0:T}", e.SignalTime); };
             t1.Start();
             Thread.Sleep(10000);
             t1.Stop();
             t1.Dispose();
         }

         static void TimeAction(object o)
         {
             Console.WriteLine("System.Threading.Timer {0:T}", DateTime.Now);
         }
