This article is to share with you the content of an example analysis of the C# thread countdown timer. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The details are as follows

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; / / timing time private TimeSpan endTime; / / time to point private Label lb;private bool whereExit = true;/// set timer timing time / timer time, for example, 01:00:00 or 1 hour public TimeHeleper (TimeSpan StartTime, Label lb) {time = StartTime This.lb = lb;} public void ShowLabel () {lb.Text = time.ToString ();} / get time / public TimeSpan GetTime () {return time;} / start timer / public void Open () {/ / calculate to point time TimeSpan tsNow = TimeSpan.Parse ("HH:mm:ss"); TimeSpan tsAdd = time;endTime = tsNow + tsAdd;// thread start whereExit = false Thread = new Thread (TimeThreadStart); thread.IsBackground = true;thread.Start ();} / turn off timer / 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 controls} Thank you for reading! This is the end of this article on "sample analysis of C# thread countdown timer".
