C#中三种Timer计时器的详细用法

//定义全局变量
public int currentCount = 0;
 
private void FrmMain_Load(object sender, EventArgs e)
{
    //设置Timer控件可用
    this.timer.Enabled = true;
    //设置时间间隔（毫秒为单位）
    this.timer.Interval = 1000;
}

private void timer_Tick(object sender, EventArgs e)
{
    currentCount += 1;
    this.txt_Count.Text = currentCount.ToString().Trim();
}

private void btn_Start_Click(object sender, EventArgs e)
{
    //开始计时
    this.timer.Start();
}

private void btn_Stop_Click(object sender, EventArgs e)
{
    //停止计时
    this.timer.Stop();
}

delegate void SetTextCallback(string text);

void timersTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    //使用代理
    string text = "子线程执行,线程ID：" + System.Threading.Thread.CurrentThread.ManagedThreadId.ToString() + "\r\n";
    SetTextCallback deg = new SetTextCallback(SetText);
    this.Invoke(deg, new object[] { text });
    i++;
}

private void SetText(string text)
{
    lblSubThread.Text += text;
}

void Main()
{
    System.Timers.Timer timersTimer = new System.Timers.Timer();
    timersTimer.Enabled = false;
    timersTimer.Interval = 100;

    //设置执行一次（false）还是一直执行(true)，默认为true
    timersTimer.AutoReset = true;

    timersTimer.Elapsed += new System.Timers.ElapsedEventHandler(timersTimer_Elapsed);
    timersTimer.SynchronizingObject = this;

}

void timersTimer_Elapsed(object sender, ElapsedEventArgs e)
{
    //e.SignalTime
}

private void Form1_Load(object sender, EventArgs e)
{
    System.Threading.Timer threadTimer = new System.Threading.Timer(new System.Threading.TimerCallback(ThreadMethod), null, -1, -1);  //最后两个参数依次为：多久后开始，隔多久执行一次。
}

public void ThreadMethod(Object state)
{
    //使用代理
    string text = "子线程执行,线程ID：" + System.Threading.Thread.CurrentThread.ManagedThreadId.ToString() + "\r\n";
    SetTextCallback d = new SetTextCallback(SetText);
    this.Invoke(d, new object[] { text });
    i++;
}

//立即开始计时，时间间隔1000毫秒:
threadTimer.Change(0, 1000);
//停止计时:
threadTimer.Change(Timeout.Infinite, 1000);
//暂停计时：
threadTimer.Change(-1， -1);
