C# 动态加载的多个UserControl 如何更新数据--------深夜在线等

Question

1.需求
1）采用UserControl布置一些控件（button、lable、pictrue）
2）将UserControl在初始化时按配置动态加载到FORM，我采用的是加载到TableLayoutPanel内
3）问题：如何快速简洁正确更新各UserControl中的button、lable、pictrue
图为动态加载后的载图
图中，有三种UserControl，每种UserControl都有可能存在几个，根据配置来的，不固定

2、我的测试代码（完全新手，完全百度）
度娘找了很多资料，最终看到某文说可以用“"list"来实现数据的操作，但具体如何做不知道。
如果有更好的办法也可以，总之，上图的Pictrue、lable、button等，可以根据实时数据更新（每个UserControl都对应一种设备）

int count = 1;
            LinkedList<UserControl> list = new LinkedList<UserControl>();//双向链表
            LinkedListNode<UserControl> linkNode = list.First;

            for (int i = 0; i < count; i++)
            {
                主枪柜_ctrl userControl1 = new 主枪柜_ctrl();
                userControl1.Parent = tableLayoutPanel1;
                userControl1.Anchor = AnchorStyles.None;
                userControl1.Dock = DockStyle.Fill;
                userControl1.title_lab.Text = "# - " + i.ToString();
                userControl1.open_door_test_btn.Name = "open_door_test_btn_" + i.ToString();
                userControl1.light_btn.Name = "light_btn_" + i.ToString();
                int userControl1length = userControl1.Size.Width / 2;
                int title_lablength = userControl1.title_lab.Size.Width / 2;
                int x = userControl1length - title_lablength;
                userControl1.title_lab.Location = new System.Drawing.Point(x, 6);

                userControl1.open_door_test_btn.Click += delegate (object sender, EventArgs e)
                {
                    open_door_test(((Button)sender).Name);
                };
                userControl1.light_btn.Click += delegate (object sender, EventArgs e)
                {
                    open_door_test(((Button)sender).Name);
                };

                list.AddLast(userControl1);

以后不要干深夜等的傻事，深夜你的帖子是待审核状态，根本就发不出来。

就你的问题，如果你希望动态更新控件，你可以
foreach (UserControl类型 uc in this.Controls.OfType())
uc.调用一个方法();

反过来，如果控件需要更新主程序，可以在控件里定义一个事件
比如你定义了一个 UpdateMainUI 的事件
那么添加创建控件的时候可以
UserControl的类型 uc = new UserControl的类型();
...
uc.UpdateMainUI += 你主窗体的一个事件函数;
在这个函数里更新
