C#Timer Interval不起作用

Question

正如标题中所写,Timer Interval中的某些内容似乎已关闭.计时器应该从"DateTimePicker"获取时间,将其转换为秒并将Interval更改为DateTimePicker上设置的时间.之后它应该在推特上发布推文,虽然它不起作用.它只是一遍又一遍地发送垃圾邮件.

            private void IntervalChoose_ValueChanged(object sender, EventArgs e) //DateTimePicker
    {
        postInterval.Interval = (IntervalChoose.Value.Hour * 3600) + (IntervalChoose.Value.Minute * 60) + IntervalChoose.Value.Second;
        saveTimerInterval = postInterval.Interval; //saveTimerInterval is set 0 at the beginning
        MessageBox.Show("Current Interval in Seconds: " + postInterval.Interval.ToString());
    }

    private void button1_Click(object sender, EventArgs e)
    {
        if (button1.Text == "Start Bot") //Starts program (works)
        {
            IntervalChoose.Enabled = false;
            MessageBox.Show(saveTimerInterval.ToString());
            postInterval.Interval = saveTimerInterval; //Sets the interval (once again, safecall)
            postInterval.Start(); //starts posting.
            button1.Text = "Stop Bot";
        }
    private void postInterval_Tick(object sender, EventArgs e)
    {
        var service = new TwitterService("", "", "", ""); //Auth Keys
        var twitterStatus = service.SendTweet(new SendTweetOptions() { Status = "Hi" + counter });
        if (twitterStatus != null)
        {
            MessageBox.Show("Your Message:\n\n\"" + "Hi" + counter + "\"\n\n has been successfully tweeted.", "Success!", MessageBoxButtons.OK);
            counter++;

        }
        else
        {
            //MessageBox.Show("An Error occured while the Bot was running. Please Contact the Developer.", "Error!", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
        }
    label2.Text = "Next Post in:\n" + (postInterval.Interval / 3600) + " Hour(s) " + ((postInterval.Interval / 3600) / 60) + " Minute(s) " + (((postInterval.Interval / 3600) / 60) / 60) + " Second(s)";
    }

结果:

如图中所示,标签不会刷新,也不会使用新的设定时间.它只是随机发布文本.在此先感谢您的帮助.

该Timer.Interval酒店有此文件:

经过的事件之间的时间(以毫秒为单位).该值必须大于零,并且小于或等于Int32.MaxValue.默认值为100毫秒.

(我的重点)

所以3930毫秒比每4秒快一点.

实现这一点的另一种方法是计算应该提交下一篇文章的DateTime,然后"经常足够"运行计时器,比如说每秒一次,并检查当前计算机时间是否已超过计算的DateTime值.

如果有,做任何事情,然后计算它应该运行的下一个时间点.
