如何在C#中从运行时获取表单中的所有控件？

using System;
using System.Windows.Forms;

namespace GetAllControls
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            GetAllControls(this);
        }

        private void GetAllControls(Control control)
        {
            foreach (Control childControl in control.Controls)
            {
                // 处理当前控件
                Console.WriteLine(childControl.Name);

                // 递归处理子控件
                GetAllControls(childControl);
            }
        }
    }
}
