我有一个运行2个计时器的Windows服务,一个是15分钟,一个是24小时。 我添加了事件日志记录来检查已过时的事件处理程序是否在15分钟内触发,但似乎没有。任何人都可以看到这个代码有什么问题?
public partial class GTstaging : ServiceBase
{
System.Timers.Timer regularTimer = new System.Timers.Timer();
System.Timers.Timer longTimer = new System.Timers.Timer();
DateTime _scheduleTime;
public staging()
{
InitializeComponent();
_scheduleTime = DateTime.Today.AddDays(1).AddHours(Convert.ToDouble(ConfigurationManager.AppSettings["ScheduleTime_" + DateTime.Now.DayOfWeek.ToString()]));
}
protected override void OnStart(string[] args)
{
//** original - ConsoleApplication1.Program.DoProcessing();
using (EventLog eventLog = new EventLog("Application"))
{
eventLog.Source = "Application";
eventLog.WriteEntry("START, regular timer:" + ConfigurationManager.AppSettings["RegularTimer"], EventLogEntryType.Information, 101, 1);
}
this.regularTimer.Enabled = true;
this.regularTimer.Interval = Convert.ToDouble(ConfigurationManager.AppSettings["RegularTimer"]);
this.regularTimer.AutoReset = true;
this.regularTimer.Elapsed += new System.Timers.ElapsedEventHandler(this.DoRegular);
this.longTimer.Enabled = true;
this.longTimer.Interval = _scheduleTime.Subtract(DateTime.Now).TotalSeconds * 1000;
this.longTimer.Elapsed += new System.Timers.ElapsedEventHandler(this.DoLongRunning);
}
private void DoRegular(object sender, System.Timers.ElapsedEventArgs e)
{
//do stuff then log
using (EventLog eventLog = new EventLog("Application"))
{
eventLog.Source = "Application";
eventLog.WriteEntry("Regular Process End", EventLogEntryType.Information, 101, 1);
}
}
private void DoLongRunning(object sender, System.Timers.ElapsedEventArgs e)
{
//do stuff
}
protected override void OnStop()
{
this.regularTimer.Stop();
this.longTimer.Stop();
this.regularTimer = null;
this.longTimer = null;
}
}
}
答案 0 :(得分:1)
我会这样调试:
在下一行放置一个BreakPoint,以确保定时器是 设置,然后在调试模式下运行应用程序:
this.longTimer.Elapsed += new System.Timers.ElapsedEventHandler(this.DoLongRunning);
如果达到上一个BreakPoint,请将定时器间隔设置为5和10 秒,只是为了测试它们是否正常工作,然后运行应用程序 调试模式:
this.regularTimer.Interval = 5000; //Convert.ToDouble(ConfigurationManager.AppSettings["RegularTimer"]);
this.longTimer.Interval = 10000; //_scheduleTime.Subtract(DateTime.Now).TotalSeconds * 1000;
然后在DoRegular
方法中放置一个BreakPoint,在DoLongRunning
方法中放一个BreakPoint并在调试模式下运行应用程序
如果您注意到某个秒后达到了DoRegular
方法
OnStartMethod
,您看到达到了DoLongRunning
方法
我们只需要检查this.regularTimer.Interval
和
this.longTimer.Interval
已使用原始来源正确设置
码。
您可以在this.longTimer.Elapsed
BreakPoint时检查其值
到达。 (请记住,该值表示为毫秒)
我希望通过这种方式修复您的代码,祝您度过愉快的一天!
