向主窗體中加A窗體
{
                bool isExitFormConfig = false;//判斷配置窗口是否已經(jīng)打開，防止重復打開多個配置窗口
                foreach (Form openForm in Application.OpenForms)
                {
                    if (openForm.Name == "A")
                    {
                        openForm.Visible = true;//如果配置窗口已打開則將其顯示
                        openForm.Activate();//并激活該窗體
                        isExitFormConfig = true;
                        break;
                    }
                }
                if (!isExitFormConfig)
                {
                   A fc = new A();
                    fc.TopLevel = false;//將被更改以使該窗體成為具有工具窗口邊界的非頂級窗體。

                    fc.Dock = DockStyle.Fill;
                    this.panel1.Controls.Add(fc);//this是你的主窗口
                    fc.Show();
                    fc.TopMost = true;
                }
            }
}

向主窗體中加B窗體

{
                bool isExitFormConfig = false;//判斷配置窗口是否已經(jīng)打開，防止重復打開多個配置窗口
                foreach (Form openForm in Application.OpenForms)
                {
                    if (openForm.Name == "B")
                    {
                        openForm.Visible = true;//如果配置窗口已打開則將其顯示
                        openForm.Activate();//并激活該窗體
                        isExitFormConfig = true;
                        break;
                    }
                }
                if (!isExitFormConfig)
                {
                   B fc = new B();
                    fc.TopLevel = false;//將被更改以使該窗體成為具有工具窗口邊界的非頂級窗體。

                    fc.Dock = DockStyle.Fill;
                    this.panel1.Controls.Add(fc);//this是你的主窗口
                    fc.Show();
                    fc.TopMost = true;
                }
            }
}

幫忙看一下代碼，加載A窗體后，加載后面的窗體B不能出現(xiàn)在最上層
如何改才能讓后來出現(xiàn)的子窗體B在最前層顯示？
