如何在运行时克隆 Control 事件处理程序? [英] How to clone Control event handlers at run time?

问题描述

我想复制一个控件，如 Button、TextBox 等.但我不知道如何将事件处理程序方法(如 Click)复制到新控件.

I want to duplicate a control like a Button, TextBox, etc. But I don't know how I can copy event handler methods (like Click) to the new control.

我现在有以下代码:

var btn2 = new Button();  
btn2.Text = btn1.Text;
btn2.size = btn1.size;
// ...
btn2.Click ??? btn1.Click

还有其他方法可以复制控件吗?

Is there any other way to duplicate a control?

推荐答案

克隆任何 WinForms 控件的所有事件:

To clone all events of any WinForms control:

var eventsField = typeof(Component).GetField("events", BindingFlags.NonPublic | BindingFlags.Instance);
var eventHandlerList = eventsField.GetValue(button1);
eventsField.SetValue(button2, eventHandlerList);
