检查控件是否在 Click EventHandler 上有事件

Check if the control has events on Click EventHandler(检查控件是否在 Click EventHandler 上有事件)

问题描述

我想知道控件是否在 Click 事件上分配了方法.

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

我需要一些至少可以告诉我控件是否对点击事件有某种方法的东西.

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