在 .NET 中查找 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 Windows 窗体 控件的所有事件处理程序?专门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 Forms 对此有很强的反制措施.大多数控件将事件处理程序引用存储在需要秘密cookie"的列表中.cookie 值是动态创建的，您无法预先猜到.反射是一个后门，你要知道cookie的变量名.例如，Control.Click 事件的名称为EventClick"，您可以在 Reference Source 或 Reflector 中看到它.

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.

这完全是不切实际的，如果你觉得你在做一些不明智的事情，那么你就在正确的轨道上.您可以在我的回答中找到执行此操作的示例代码 这个帖子.

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.
