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一个不同的方法/函数，但我真的不确定句法。我应该怎么做？

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?

我想我会和这个代表团一起去，但问题仍然很有意思。

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

推荐答案

真的没有一个事件数组的概念 - 就像谈论一个属性数组。事件真的只是让您订阅并取消订阅处理程序的方法。如果你需要通过索引来做到这一点，我建议你只需要一个方法。 （ AddCommandHandler（int，RecvCommandHandler）和 RemoveCommandHandler（int，RecvCommandHandler））。这不支持正常的事件处理语法糖，当然，但我看不到有很多替代方案。

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.
