接口和事件

本文介绍了接口和事件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

大家好，我需要一些关于接口和代表的建议。 我想在接口内定义一个委托（我知道一个 代表是一个班级，但是听我说话） 这是一个样本： 接口A B级继承接口A 程序C创建一个B类实例，需要消耗来自B类的事件 我希望B类通过 接口A来实现代表。这可能吗？这是对的吗？可以/我应该使用 抽象类吗？有更好的方法吗？

Hey everyone, I need some advice concerning Interfaces and delegates. I would like to define a delegate inside of an interface (I know a delegate is a class but hear me out) Here is a sample: Interface A Class B inherits Interface A Program C creates an instance of Class B and needs to consume events from Class B. I would like for Class B to be required to implement the delegates via Interface A. Is this possible? Is this proper? Can/Should I use an abstract class for this? Is there a better way?

推荐答案

听起来像是一个管道。我会使用 消息传递，而不是使用委托和事件。每个类都会公开一个有界队列（阻塞样式） 并在消息上有一个工作线程（或用户TP）块并处理它们需要 。 - William Stacey [MVP] < go ******** @ gmail。 COM>在留言中写道 news：11 ********************** @ f14g2000cwb.googlegr oups ...... |嘿大家，我需要一些关于接口和代表的建议。 | |我想在界面中定义一个委托（我知道一个 |委托是一个班级，但是听我说） | | |这是一个样本： | |接口A | | B类继承了接口A | |程序C创建一个B类实例，需要消耗事件 |来自B班。 | |我希望B级要求通过 |来实现代表接口A.这可能吗？这是对的吗？可以/应该使用 |抽象类为此？有更好的方法吗？ | Sounds like a pipeline.

William， 谢谢你。很遗憾我不知道如何实现你所说的b $ b。你可以用正确的 方向指出我（和其他人读这篇文章）吗？ 问候.. " William Stacey [MVP] QUOT; <无线************ @ gmail>在消息中写道 新闻：Od **************** @ TK2MSFTNGP15.phx.gbl ...

您当然可以在界面中包含事件（而不是代理）。 它不是非常常见，但在某些情况下这是有道理的。 - Jon Skeet - < sk *** @ pobox> www.pobox/~skeet 博客： www.msmvps/jon.skeet 如果回复该组，请不要给我发邮件

You can certainly include events (not delegates) within interfaces. It''s not terribly common, but it makes sense in certain situations. -- Jon Skeet - <sk***@pobox> www.pobox/~skeet Blog: www.msmvps/jon.skeet If replying to the group, please do not mail me too
