C# 通过System.Timers.Timer获取时间

 1 public delegate void timeDelegate();// Timer获取时间
 2 
 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）

10 private void Timer_TimesUp(object sender, System.Timers.ElapsedEventArgs e)
11 {
12     timeDelegate td = new timeDelegate(timeChange);
13     this.BeginInvoke(td);

17     int hour = System.DateTime.Now.Hour;
18     int minute = System.DateTime.Now.Minute;
19     int second = System.DateTime.Now.Second;
20     textBox1.Text = hour.ToString();
21     textBox2.Text = minute.ToString();
22     textBox3.Text = second.ToString();
