查找在.NET Windows窗体控件的所有事件处理程序 [英] Find all event handlers for a Windows Forms control in .NET

问题描述

有没有办法找到一个 Windows窗体控制所有事件处理程序？特别是静态定义的事件处理程序？

Is there a way to find all event handlers for a Windows Forms control? Specifically statically defined event handlers?

推荐答案

Windows窗体具有较强的反制措施反对这样做。大多数控件存储，需要一个秘密的饼干列表中的事件处理程序的参考。 cookie的值是动态创建的，你不能猜测它前面。反思是一个后门程序，你必须知道cookie的变量名。一个为Control.Click活动被命名为EventClick为例，你可以看到这个在参考源或反射器。

Windows Forms has strong counter-measures against doing this. Most controls store the event handler reference in a list that requires a secret 'cookie'. The cookie value is dynamically created, you cannot guess it up front. Reflection is a backdoor, you have to know the cookie variable name. The one for the Control.Click event is named "EventClick" for example, you can see this in the Reference Source or with Reflector.

这是所有令人难以置信不现实的，如果你要，你正在做的事情是不明智的感觉，那么你是在正确的轨道。你可以找到样本code，这是否在我的答案在<一个href="http://stackoverflow.com/questions/293007/is-it-possible-to-steal-an-event-handler-from-one-control-and-give-it-to-anothe/293031#293031">this螺纹。

This is all incredibly unpractical, if you're getting the feeling you are doing something unwise then you're on the right track. You can find sample code that does this in my answer in this thread.
