将子控件上按钮的点击事件传递给父控件

如何解决将子控件上按钮的点击事件传递给父控件

我有一个父表单 FormSubscribingToTheEvent 和一个子表单 FormThatThrowsTheEvent 子窗体有一个按钮。当单击子窗体上的按钮时，我希望通知父窗体并且 MessageBox 显示消息："The Close button was clicked."

我找到了帖子：“将子控件的点击事件传递给父控件” Pass click event of child control to the parent control 并且我遵循了 Reza Aghaei 的说明，这是唯一且可接受的答案。

不幸的是，我收到错误消息："An unhandled exception of type 'System.StackOverflowException' occurred in PassClickEventOfChildControlToTheParentControl.exe"

代码：

    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;

    namespace PassClickEventOfChildControlToTheParentControl
    {
        public partial class FormSubscribingToTheEvent : Form
        {
            public FormSubscribingToTheEvent()
            {
                InitializeComponent();

                FormThatThrowsTheEvent instanceOfFormThatThrowsTheEvent = new FormThatThrowsTheEvent();
                instanceOfFormThatThrowsTheEvent.CloseButtonClicked += new EventHandler(instanceOfFormThatThrowsTheEvent.CloseButton_Click);
                instanceOfFormThatThrowsTheEvent.Show();
            }

            private void InstanceOfFormThatThrowsTheEvent_CloseButtonClicked(object sender,EventArgs e)
            {
                MessageBox.Show("The Close button was clicked.");
            }
        }
    }    
    
    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;

    namespace PassClickEventOfChildControlToTheParentControl
    {
        public partial class FormThatThrowsTheEvent : Form
        {
            public event EventHandler CloseButtonClicked;

            public FormThatThrowsTheEvent()
            {
                InitializeComponent();
            }

            public void CloseButton_Click(object sender,EventArgs e)
            {
                OnCloseButtonClicked(e); // !!! An unhandled exception of type 'System.StackOverflowException' occurred in PassClickEventOfChildControlToTheParentControl.exe
            }

            /// <summary>
            /// To raise the XXXX event,it is enough to invoke the XXXX event delegate.
            /// the reason for creating the protected virtual OnXXXX is just to follow the pattern to let the derivers override the method 
            /// and customize the behavior before/after raising the event.
            /// </summary>
            /// <param name="e"></param>
            protected virtual void OnCloseButtonClicked(EventArgs e)
            {
                CloseButtonClicked.Invoke(this,e); // !!! An unhandled exception of type 'System.StackOverflowException' occurred in PassClickEventOfChildControlToTheParentControl.exe
            }
        }
    } 

请解释我做错了什么，以及如何更正代码，以便父窗体收到子窗体上的按钮单击事件和 MessageBox 的通知以显示消息："The Close button was clicked."
