想了解Winform基于多线程实现每隔1分钟执行一段代码的相关内容吗,在本文为您仔细讲解Winform每隔1分钟执行一段代码的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Winform,多线程,每隔,1分钟,执行,代码,下面大家一起来学习吧。

本文实例讲述了Winform基于多线程实现每隔1分钟执行一段代码的方法,分享给大家供大家参考。具体实现方法如下:

1.定义相关的类Timer.cs,代码如下:

复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;

namespace SMIS2013.DSS.Monitor
{
    public class MyTimer
    {
        public delegate void Elapsed(); //定义委托 
        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.在主线程部分引用此类。在需要执行的event加入:

复制代码 代码如下:
private const int _Interval =40000;
        private MyTimer _Timer;

  private void Form1_Load(object sender, EventArgs e)
        {

            _Timer = new MyTimer();
            _Timer.Interval = _Interval;
            _Timer.Start(); //开始
            _Timer.OnElapsed += Timer_OnElapsed;
        }
 void Timer_OnElapsed()
        {
            Invoke(new Action(() => 加入需要执行的event));
            //to do
        }

private void Form1_FormClosed(object sender, FormClosedEventArgs e)

{

//记得需要结束

if (_Timer != null)

{

_Timer.OnElapsed -= Timer_OnElapsed;

_Timer.Stop();

}

}

希望本文所述对大家的C#程序设计有所帮助。
