检查控件是否有单击EventHandler的事件 [英] Check if the control has events on Click EventHandler

问题描述

 按钮b = new Button（） ; 
 b.Click + =（sender，e）=> {}; 
 
 / *我想要什么* / 
 b.Click.Count // 1 
  

我需要一些东西，至少可以告诉我控件是否有一些点击事件的方法。

解决方案

您可以阅读本主题确定事件处理程序的列表绑定到事件，似乎它可能与您尝试做什么有关。

I want to know if a control has a method assigned on the Click event.

Button b = new Button();
b.Click += (sender, e) => { };

/* What I want */
b.Click.Count // 1

I need something that can at least tell me if the control has or not some method on the click event.

解决方案

You might do some reading into this topic Determine list of event handlers bound to event , it appears that it may be somewhat related to what you are trying to do.
