C# 通过System.Timers.Timer获取时间

 1 public delegate void timeDelegate();// Timer获取时间

 3 private void Form1_Load(object sender, EventArgs e)
 4 {
 5     System.Timers.Timer t = new System.Timers.Timer(1000); //设置时间间隔为5秒
 6     t.Elapsed += new System.Timers.ElapsedEventHandler(Timer_TimesUp);
 7     t.Enabled = true; //是否触发Elapsed事件
 8     t.AutoReset = true; //每到指定时间Elapsed事件是触发一次（false），还是一直触发（true）
