线程之间的事件上升 [英] Rising events between threads

问题描述

大家好，


我最近深入研究了C＃和整个.Net的东西。特别是我

发现了将事件和代表添加到C＃语言中的想法非常有趣，我正试图以各种奇怪的方式使用它们

在我看来。特别是我很难找到一种方法来使用线程之间的事件

。


特别是我想知道如何上升和事件从一个线程和

从另一个线程中的委托收到它（我的意思是另一个

线程唤醒并执行委托）...并且继续...它是否可以播放活动？
？或者，甚至更好，决定

目标线程？


我记得过去那里有窗口中的消息，而不是

事件，你可以安全地通过线程发送它们。但他们是不同的东西，我认为，代表只是功能指针

和事件是捆绑的（好吧，可能还有一些额外的东西）...


那么可以用事件做到这一点吗？或者还有其他方式，

同样简单方便（我不是关于Monitor，Mutex和

co ...我知道他们......）？


提前致谢。再见。

Hi all,

I''ve recently digged into C# and the whole .Net stuff. Particularly I
found the idea of adding Events and Delegates to the C# language very
interesting and I''m trying to use them in every weird way that comes
to my mind. Particularly I''m struggling to find a way to use events
between threads.

In particular I''d like to know how to rise and event from a thread and
have it received from the delegate in another thread (I mean the other
thread wakes up and executes the delegate)... And going over... is it
possible to broadcast events? Or, even better, to decide the
destination thread?

I remember that in the past there where messages in windows, not
events, and you could send them through threads safely. But they were
a different thing cos, I think, delegates are just function pointers
and events are bundles of them (ok, with some extras maybe)...

So is it possible to do this with events? Or are there other ways,
similarly easy and convenient (I''m not taling about Monitor, Mutex and
co... I know them...)?

Thanks in advance. Bye.

推荐答案

你不能在没有

的情况下将一个调用注入到另一个线程的调用堆栈中做一些事情的线程被通知来电。这是

为什么你可以在UI线程上调用委托。因为UI线程有一个循环循环的消息泵，你可以注入一些东西来处理这个循环，在这种情况下，你的委托调用。


对于其他线程，你几乎必须做同样的事情，就是说，

有一个循环等待执行你的委托的信号。

You can not inject a call into the call stack of another thread without
that thread doing something to be notified of the incoming call. This is
why you can have delegates called on a UI thread. Because the UI thread has
a message pump that cycles in a loop, you can inject something to be
processed into that loop, in this case, your delegate call.

For other threads, you pretty much have to do the same thing, that is,
have a loop waiting for a signal to execute your delegate.

就像我告诉你的那样，你基本上必须在你的主题中有一个循环

将处理在其他线程上设置的消息/通知。

您可以使用Windows消息，某种队列结构等等。这是

a基本的生产者/消费者模式。


是否有一个特殊原因，你想拥有一个单独的线程

流程代表？你究竟想做什么？

Just like I told you, you basically have to have a loop in your thread
which will process messages/notifications which are set on other threads.
You can use windows messages, some sort of queue structure, etc, etc. It''s
a basic producer/consumer pattern.

Is there a particular reason why you want to have one single thread
process delegates? What exactly are you trying to do?
