本文實(shí)例講述了Winform基于多線程實(shí)現(xiàn)每隔1分鐘執(zhí)行一段代碼的方法，分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：
1.定義相關(guān)的類Timer.cs，代碼如下：
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace SMIS2013.DSS.Monitor
{
public class MyTimer
{
public delegate void Elapsed(); //定義委托
public event Elapsed OnElapsed;
private long _Interval = 1000;
public long Interval
{
get { return _Interval; }
set { _Interval = value; }
}
private bool _IsStart = false;
private Thread _TimerThread;
public void Start()
{
if (_IsStart)
return;
_IsStart = true;
_TimerThread = new Thread(new ThreadStart(DoTimer));
_TimerThread.Start();
}
public void Stop()
{
try
{
if (!_IsStart)
return;
_IsStart = false;
_TimerThread.Abort();
}
catch (Exception e)
{ }
}
private void DoTimer()
{
try
{
int last = Environment.TickCount;
while (_IsStart)
{
if (Environment.TickCount - last > _Interval)
{
if (OnElapsed != null)
OnElapsed();
last = Environment.TickCount;
}
Thread.Sleep(100);
}
}
catch (Exception e)
{ }
}
}
}
2.在主線程部分引用此類。在需要執(zhí)行的event加入：
private MyTimer _Timer;
private void Form1_Load(object sender, EventArgs e)
{
_Timer = new MyTimer();
_Timer.Interval = _Interval;
_Timer.Start(); //開始
_Timer.OnElapsed += Timer_OnElapsed;
}
void Timer_OnElapsed()
{
Invoke(new Action(() => 加入需要執(zhí)行的event));
//to do
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
//記得需要結(jié)束
if (_Timer != null)
{
_Timer.OnElapsed -= Timer_OnElapsed;
_Timer.Stop();
}
}
希望本文所述對(duì)大家的C#程序設(shè)計(jì)有所幫助。
