是否可以订阅C＃中的事件订阅？ [英] Is it possible to subscribe to event subscriptions in C#?

问题描述

如果我有这样的事件：

public delegate void MyEventHandler(object sender, EventArgs e);
public event MyEventHandler MyEvent;

并添加了一个这样的事件处理程序：

And adds an eventhandler like this:

MyEvent += MyEventHandlerMethod;

...是否可以以某种方式注册？换句话说 - 可以有如下的东西：

... is it then possible to register this somehow? In other words - is it possible to have something like:

MyEvent.OnSubscribe += MySubscriptionHandler;

推荐答案

类似于自动实现的属性，

Similar to auto-implemented properties, events are auto-implemented by default as well.

您可以如下扩展事件的声明：

You can expand the declaration of an event as follows:

public event MyEventHandler MyEvent
{
    add
    {
        ...
    }
    remove
    {
        ...
    }
}

请参阅如何使用字典存储事件实例（C＃编程指南）

请参阅事件在C＃4中第一部分：Locks 关于C＃3和C＃4之间的自动实施事件的不同

See Events get a little overhaul in C# 4, Part I: Locks for how auto-implemented events differ between C# 3 and C# 4.
