Winform基于多线程实现每隔1分钟执行一段代码

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：

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：

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。
