C#线程倒计时器源码分享
本文实例为大家分享了C#线程倒计时器源码,供大家参考,具体内容如下
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading; using System.Windows.Forms; namespace ListZZBG { class TimeHeleper { Thread thread; private TimeSpan time; //计时时间 private TimeSpan endTime; //到点时间 private Label lb; private bool whereExit = true; /// <summary> /// 设定计时器计时的时间 /// </summary> /// <param name="StartTime">计时器时间,如:01:00:00 既1小时</param> public TimeHeleper(TimeSpan StartTime, Label lb) { time = StartTime; this.lb = lb; } public void ShowLabel() { lb.Text = time.ToString(); } /// <summary> /// 获取时间 /// </summary> /// <returns></returns> public TimeSpan GetTime() { return time; } /// <summary> /// 开启计时器 /// </summary> public void Open() { //计算到点时间 TimeSpan tsNow = TimeSpan.Parse(DateTime.Now.ToString("HH:mm:ss")); TimeSpan tsAdd = time; endTime = tsNow + tsAdd; //线程开始 whereExit = false; thread = new Thread(TimeThreadStart); thread.IsBackground = true; thread.Start(); } /// <summary> /// 关闭计时器 /// </summary> public void Close() { whereExit = true; thread.Join(1000); } private void TimeThreadStart() { while (!whereExit) { RunTime(); Thread.Sleep(1000); } } private delegate void RunTimeDelegate(); private void RunTime() { if (lb.InvokeRequired) { RunTimeDelegate d = RunTime; lb.Invoke(d); } else { time = endTime - TimeSpan.Parse(DateTime.Now.ToString("HH:mm:ss")); string[] sp = time.ToString().Split(':'); lb.Text = sp[2].ToString(); //liable1控件 } } } }
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
