将指令发送给一个线程正在等待对TCP？ [英] Sending instructions to a thread which is waiting for TCP?

问题描述

我想了解的多线程TCP所以我编码一个基本的Telnet文本路由器。

I'm trying to understand multi-threading in TCP so I'm coding a basic telnet text "router".

使用的ReadLine（）使用一个TCP监听器将等待来自Telnet客户端输入，然后每个线程响应此基础上发送的文本。我有这个正与多线程和多telnet客户端。

using ReadLine() each thread using a TCP listener will wait for input from the telnet client and then respond based on the text which is sent. I have this working with multiple threads and multiple telnet clients.

我要有条件地将消息发送到所有线程。 例如，如果从任何一个线程发出的文本是警报！然后，我想每一个线程连接的客户端执行的WriteLine（警报！）

I want to conditionally send messages to all threads. For example, if the text sent from any one thread is "Alert!" then I want every thread for connected clients to execute WriteLine("Alert!")

这是否有道理？ 我的问题是，我不知道如何让一个线程引发一个事件在另一个线程。

Does this make sense? My problem is that I don't know how to make one thread raise an event in another thread.

推荐答案

您需要看一个事件代理模式。基本上你将有你的所有线程订阅事件的一个对象。它也将有一个可以被称为将调用该事件的方法。这也许听起来很复杂，但它相当简单。

You need to look at a Event Broker pattern. Basically you would have one object with an event that all your threads subscribe to. It will also have a method that can be called which will invoke the event. It maybe sounds complicated, but its fairly simple.
