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。
