如何订阅另一个程序集中引发的事件
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。当它完成回调时，它会引发一个事件 SomethingCompleted。 如何从同一解决方案中的另一个项目订阅此事件？
我在接收项目中内置了事件处理程序，但在发送项目中看不到该事件。
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?
I have the event handlers built in the receiving project but it does not see the event in the sending project.

在单独的程序集中引发的事件没有什么特别之处，除非事件本身是使用
internal访问修饰符声明的。检查它是否是公开的。举个例子来说明我的意思，我确信您不会再三考虑订阅
Button.Click- 但Button位于不同的程序集中，不是”是吗？There's nothing special about events raised in a separate assembly, unless the event itself is declared with the
internalaccess modifier. Check that it's public.To give an example of what I mean, I'm sure you don't think twice about subscribing to
Button.Click- butButtonis in a different assembly, isn't it?该事件必须在定义它的类中声明为公共：
然后您可以像订阅任何其他事件一样订阅它：
The event must be declared as public in the class which defines it:
You can then subscribe to it just as to any other event:
您需要引用引发事件的类来注册事件处理程序。
完成后，就像注册任何其他事件处理程序一样完成：
You need to have a reference to the class raising the event to register an event handler.
Once you have that, it's done like registering any other event handler:
