在C＃中将实例方法传递给线程 [英] Passing Instance Method to Thread in C#

问题描述

我想同时从另一个类运行两个方法。显然，下面的代码不起作用。我怎么能这样做？

节点node =  new 节点（）; 
 EHNode ehnode =  new  EHNode（）; 
 
线程normalNode =  new 线程（node.RunNode（））; 
线程ehNode = 新线程（ehnode.RunNode（））; 
 
 normalNode.Start（）; 
 ehNode.Start（）; 

解决方案

是的，这个问题很有意思。我解决这个问题的方法是使用线程包装器。这个想法是：将this传递给线程，该线程是对包装器的引用。这将打开线程代码的包装器的所有实例成员（不仅是实例方法）。 （如果你共享任何一个，不要忘记使用线程同步，但线程包装器也有助于很好地封装同步原语。）

你明白了吗？

< blockquote>你有 Node 和 EHNode 的来源，是吗？然后你可以添加一个方法 StartRunNode（），它用 RunNode（）创建一个新线程，启动它，然后返回到来电者。

I want to run two methods from another class simultaneously. Obviously, the code below will not work. How can I do something like this?

Node node = new Node();
EHNode ehnode = new EHNode();

Thread normalNode = new Thread(node.RunNode());
Thread ehNode = new Thread(ehnode.RunNode());

normalNode.Start();
ehNode.Start();

解决方案

Yes, the question is interesting. My method of solving such problem is using a thread wrapper. The idea is: pass "this" to the thread, which is the reference to the wrapper. This will open all the instance members (not only instance methods) of the wrapper to the thread code. (Don''t forget to use thread synchronization if you share any of them, but a thread wrapper also helps to encapsulate the synchronization primitives nicely.)

Did you get the idea?

—SA

Do you have the sources for Node and EHNode, resp.? Then you could add a method StartRunNode() which creates a new thread with RunNode(), starts it, and returns to the caller.
