C# winform usercontrols之间的通信以将tab添加到tabcontrol

我想在单击按钮后添加一个选项卡页。对我来说，困难在于我用按钮得到了一个UserControl，而tabpage是一个UserControl，我想用TabControl将它添加到现有的UserControl中

下面是我要添加的选项卡的Usercontrol：

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

namespace Demo
{
    public partial class TabsTravel : UserControl
    {
        private static DateTime ArrivalStart;
        public static DateTime arrivalStart
        {
            get { return ArrivalStart; }
            set { ArrivalStart = value; }

        }

        private static DateTime ArrivalEnd;
        public static DateTime arrivalEnd
        {
            get { return ArrivalEnd; }
            set { ArrivalEnd = value; }

        }

        private static DateTime DepartureStart;
        public static DateTime departureStart

        }

        private static DateTime DepartureEnd;
        public static DateTime departureEnd

这里我得到了UserControl A中的按钮和addTab方法：

public delegate void tabWork(TabControl tabsWork);

private void btnAddWorker_Click(object sender, EventArgs e)
        {

            addTab(tabsTravel);

        }

        static void addTab(TabControl tabsTravel) 
        {

            string title = "worker " + (tabsTravel.TabCount + 1).ToString();

            TabPage travel = new TabPage();
            tabWork work;

            tabsTravel.TabPages.Add(travel);
            travel.Text = title;
            travel.BackColor = Color.White;
            travel.Controls.Add(new TabsTravel());

            work = new tabWork(Page3.addTab);



        }

这里我得到了UserControl B中的addTab方法：

public static void addTab(TabControl tabsWork) 
        {
            TabsWork work = new TabsWork();
            TabPage Tabwork = new TabPage();
            string title = "worker " + (tabsWork.TabCount + 1).ToString();

            tabsWork.TabPages.Add(Tabwork);
            Tabwork.Text = title;
            Tabwork.BackColor = Color.White;
            Tabwork.Controls.Add(new TabsWork());

        }

但是UserControl B中的addTab从未被调用

我如何解决这个问题？

你应该创建一个事件，通知另一个用户控件创建/添加另一个选项卡，传递一个对象，其中包含你想在另一个用户控件中获得的信息

，而我对C“非常陌生”#你能给我一个例子吗？看看这里，研究一下，因为你将更多地作为一个程序员使用它，好吗现在谢谢你。如果我有什么问题，我会回来的。你能再给我一个提示吗？

public static void addTab(TabControl tabsWork) 
        {
            TabsWork work = new TabsWork();
            TabPage Tabwork = new TabPage();
            string title = "worker " + (tabsWork.TabCount + 1).ToString();

            tabsWork.TabPages.Add(Tabwork);
            Tabwork.Text = title;
            Tabwork.BackColor = Color.White;
            Tabwork.Controls.Add(new TabsWork());

        }
