问题描述
为什么我的DispatcherTimer不与Windows服务工作。
背后的目的,我想使用DispatcherTimer用于检查一个窗口服务许可证
公共OIMService()
{
的InitializeComponent();
_dispatcherTimer =新DispatcherTimer();
如果(System.Diagnostics.EventLog.SourceExists(OIM_Log)!)
{
EventLog.CreateEventSource(OIM_Log,OIMLog);
}
EventLog.Source =OIM_Log;
EventLog.Log =OIMLog;
_helpers =新ValidationHelpers();
startTimer所();
}
保护覆盖无效的OnStart(字串[] args)
{
System.Diagnostics.Debugger.Launch();
如果(_helpers.IsValid())
{
ConfigureServer();
startTimer所();
}
,否则
{
this.Stop();
}
}
私人无效startTimer所()
{
const int的时间= 10;
_dispatcherTimer.Tick + =新的EventHandler(DispatcherTimerTick);
_dispatcherTimer.Interval =新时间跨度(0,0,Convert.ToInt32(时间));
_dispatcherTimer.IsEnabled = TRUE;
_dispatcherTimer.Start();
}
私人无效DispatcherTimerTick(对象发件人,EventArgs五)
{
EventLog.WriteEntry(测试测试测试...);
}
的点 DispatcherTimer
是消防调度线程上的勾选
事件。这是因为你只能操纵调度线程上的Silverlight / WPF UI元素是很重要的。在Windows服务中,有是的没有调度线程进行...有没有UI操控。你为什么要使用的 DispatcherTimer
而不是(说)的?
Why my DispatcherTimer don't work with Windows Service .
The purpose behind that i want use DispatcherTimer for check a windows service License
public OIMService()
{
InitializeComponent();
_dispatcherTimer = new DispatcherTimer();
if (!System.Diagnostics.EventLog.SourceExists("OIM_Log"))
{
EventLog.CreateEventSource("OIM_Log", "OIMLog");
}
EventLog.Source = "OIM_Log";
EventLog.Log = "OIMLog";
_helpers = new ValidationHelpers();
StartTimer();
}
protected override void OnStart(string[] args)
{
System.Diagnostics.Debugger.Launch();
if (_helpers.IsValid())
{
ConfigureServer();
StartTimer();
}
else
{
this.Stop();
}
}
private void StartTimer()
{
const int time = 10;
_dispatcherTimer.Tick += new EventHandler(DispatcherTimerTick);
_dispatcherTimer.Interval = new TimeSpan(0, 0, Convert.ToInt32(time));
_dispatcherTimer.IsEnabled = true;
_dispatcherTimer.Start();
}
private void DispatcherTimerTick(object sender, EventArgs e)
{
EventLog.WriteEntry("test test test ...");
}
The point of DispatcherTimer
is to fire its Tick
event on the dispatcher thread. That's important because you can only manipulate Silverlight/WPF UI elements on the dispatcher thread. In a Windows Service, there is no dispatcher thread... there's no UI to manipulate. Why would you want to use a DispatcherTimer
instead of (say) System.Timers.Timer
?
