C#中的事件数组? [英] array of events in C#?

问题描述

基本上:

public delegate void RecvCommandHandler (ChatApplication sender, byte[] content);
event RecvCommandHandler[] commands = new RecvCommandHandler[255];

我想为每个命令编号激活不同的方法/函数，但我真的不确定语法.我该怎么做?

I want to activate a different method/function for each command number, but I am really uncertain of the syntax. How am I supposed to do it?

对于这个问题，我想我只会用一组代表，但这个问题仍然很有趣.

I think I'll go with just an array of delegates for this one, but the question is still interesting.

推荐答案

实际上没有事件数组的概念 - 就像谈论属性数组一样.事件实际上只是让您订阅和取消订阅处理程序的方法.如果您需要能够通过索引来做到这一点，我建议您只需要一对方法.(AddCommandHandler(int, RecvCommandHandler) 和 RemoveCommandHandler(int, RecvCommandHandler)).当然，这不会支持正常的事件处理语法糖，但我认为没有很多替代方案.

There's really no concept of an array of events - it's like talking about an array of properties. Events are really just methods which let you subscribe and unsubscribe handlers. If you need to be able to do this by index, I suggest you just have a pair of methods. (AddCommandHandler(int, RecvCommandHandler) and RemoveCommandHandler(int, RecvCommandHandler)). That won't support the normal event handling syntactic sugar, of course, but I don't see that there's a lot of alternative.
