我如何订阅另一个大会中提出的事件 [英] how do I subscribe to an event in raised in another assembly

问题描述

我有一个包含3个项目的解决方案.一个项目处理异步通信.完成回调后，将引发事件SomethingCompleted. 如何在同一解决方案中从另一个项目订阅此事件?

I have a solution which contains 3 project. One project handles asynchronous communinications. When it has completed it's callback, it raises an event SomethingCompleted. How do I subscribe to this event from another project in the same solution?

我在接收项目中内置了事件处理程序，但是在发送项目中看不到该事件.

I have the event handlers built in the receiving project but it does not see the event in the sending project.

推荐答案

您需要引用引发事件的类以注册事件处理程序.

You need to have a reference to the class raising the event to register an event handler.

一旦有了它，就像注册其他任何事件处理程序一样:

Once you have that, it's done like registering any other event handler:

foo.SomethingCompleted += (sender, e) => this.DoSomething();
