Thread.sleep代码 [英] Thread.Sleep
问题描述
如果你想继续阅读物品的价值（10秒）
不断变化，
你会怎么做？我试过这个，但是没用了
线程th =新线程（新的ThreadStart（自述文件））;
th.Start（）;
Thread.Sleep（3000）;
th.Abort（）;
Thread.Sleep（1000）;
If you want to keep reading the value of a property (10 seconds) that
keeps changing,
how would you do it. I tried this, but it did not work
Thread th = new Thread(new ThreadStart(ReadMe));
th.Start();
Thread.Sleep(3000);
th.Abort();
Thread.Sleep(1000);
推荐答案
JPSutor，
我不会使用像这样的轮询机制。相反，我会在课堂上有一些
类型的通知，指示属性何时发生变化。
框架有这样的标准。
第一个（.NET 2.0之前的版本）是在您的班级上有一个名为
< property name>已更改的事件。此事件的类型为EventHandler，当事件发生更改时，您将触发它。
如果您使用的是.NET 2.0，则应使用INotifyPropertyChanged
界面指示属性何时发生变化（
一般比旧方法更有效）。
如果你想要调查属性，然后我会使用一个计时器，而不是
导致线程进入睡眠状态，并检查那里的属性值。
希望这有帮助。

JPSutor,
I wouldn''t use a polling mechanism like this. Rather, I would have some
sort of notification on class which indicates when the property changes.
The framework has a standard for things like this.
The first (pre .NET 2.0) is to have an event on your class named
<property name>Changed. This event is of type EventHandler, and you fire it
when the event changes.
If you are using .NET 2.0, you should use the INotifyPropertyChanged
interface to indicate when a property changed (it''s more efficient in
general than the old method).
If you want to poll the property, then I would use a timer, instead of
causing a thread to sleep, and check the property value there.
Hope this helps.

我也可能会添加一个具有睡眠持续时间的while循环非常好地工作。我注意到在.Net 2.0之前，计时器在某些情况下不够可靠
。一个while循环似乎可以作为替代
解决方案。

I might also add that a while loop with a sleep duration works quite
well. I noticed in pre .Net 2.0 the timer just wasn''t reliable enough
in certain situations. A while loop seemed to work well as an alternate
solution.

Thread th = new Thread(new ThreadStart(ReadMe));
th.Start();
Thread.Sleep(3000);
th.Abort();
Thread.Sleep(1000);
这不起作用导致Thread.Sleep引用当前线程，
。
无需调用Abort顺便说一句。
ITOH，我不会这样做就这样，我会用一个计时器。
甚至更好的活动。

This does not work cause Thread.Sleep refer to the current thread , the
thread where the method is called, for this to work Thread.Sleep should be
in the ReadMe() method.
No need to call Abort btw.
ITOH, I would not do it this way, I would use a timer .
Or even better an event.
