推荐答案

，您正在创建RoomDiagram类的新实例，然后尝试将其删除.所以它不起作用.

试试

you are creating the new instance of the RoomDiagram class and then trying to remove it. So it is not working.

Try

maincDockPanel.Children.Clear();
maincDockPanel.Children.Add(new UserControl2());

它将删除DockPanel的所有子元素.如果要删除特定的控件，请使用控件的ID.

It will remove all the child elements of the DockPanel. If you want to remove the specific one then use the ID of the control.

maincDockPanel.Children.Remove(ControlID);
