c# - Unity IOC 与 winforms MVP 多个实例

Question

我想要做的是在主窗体内多次启动一个窗体，我在视图和演示者之间有 1 对 1 的关系。因此，当 presnter 或 view 被处理时，它们都会从内存中释放

我只是不知道如何实现这一点。

我能够成功启动标签表单一次，但是在我的按钮上单击我想启动更多标签表单。

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        var unityContainer = new UnityContainer();
        unityContainer.RegisterType<IMainViewUC, MainViewUC>(new ContainerControlledLifetimeManager());

        IMainPresenter mainPresenter = unityContainer.Resolve<MainPresenter>();
        IMainViewUC mainView = mainPresenter.GetView();
        Application.Run((MainViewUC)mainView);

    void IMainPresenter.OnTagsView()

    {
        ((IMainViewUC)this).TagsViewEventRaised();
    }
  
}
