 if (!existed_channel.Contains(channel_name))
            {

                if (x)
                {
                    tabpagex.BackColor = Color.Ivory;

                    tabControl1.TabPages.Add(tabpagex);

                    client_chat c = new client_chat(channel_name, owner);   //Here the client_chat is my Winform that do all the chatting thing.
                    c.TopLevel = false;
                    c.Visible = true;
                    c.BackColor = Color.Ivory;
                    c.FormBorderStyle = FormBorderStyle.None;
                    c.Dock = DockStyle.Fill;
                    tabControl1.TabPages[tab_index].Controls.Add(c);   //Here i fill up the tabpage with client_chat winform

                    tab_index++;                        //Increment the index everytime i add an tabpage.
                    existed_channel.Add(channel_name);  //Add the name of the page to an arraylist, to make sure everytime there is no duplicate page
                }
            }

如您所见，当我关闭其中一个 Winform（在标签页上）时，我必须发回数据并修改 tab_index。我可以同时关闭 Winform 和标签页，但很难将数据发回。我知道如何将数据从 childForm 发送回 parentForm，但这里的情况略有不同。

您可以在所有控件都可以访问的父级上使用全局属性
