在 UWP 中的辅助监视器上打开新窗口 [英] Open new window on secondary monitor in UWP

问题描述

我有一个带有两个显示器的 UWP 项目，我想用它在辅助显示器上打开一个新窗口.应用包括三个部分:

I have a UWP project with two monitors that I want to use to open a new window on a secondary monitor. The application includes three parts:

1. 在第一台显示器上打开主页
2. 创建新页面
3. 在辅助监视器上打开

第一和第二部分我写对了，但我找不到第三部分的解决方案.

I wrote the first and second parts correctly, but I can't find a solution for the third part.

请帮我将窗口移到另一台显示器上.

Please help me with moving the window to another monitor.

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();

      //called creat new page function
        NewWindow();
    }

    private async void NewWindow()
    {
        var myview = CoreApplication.CreateNewView();
        int newid = 0;
        await myview.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        {
            Frame newframe = new Frame();
            newframe.Navigate(typeof(Newpage), null);

            Window.Current.Content = newframe;
            Window.Current.Activate();
            ApplicationView.GetForCurrentView().Title = "Z";

            newid = ApplicationView.GetForCurrentView().Id;
        });

        await ApplicationViewSwitcher.TryShowAsStandaloneAsync(newid, ViewSizePreference.UseMinimum);

    }

}

推荐答案

我找到了解决方案并使用了 ProjectionManger 类.

I found the solution and used ProjectionManger Class.

 private async void expand()
    {
        var NewWindow = CoreApplication.CreateNewView();
        int Windowid = ApplicationView.GetForCurrentView().Id;
        int NewWindowid = 0;

        await NewWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        {
            Frame newframe = new Frame();
            newframe.Navigate(typeof(Newpage), null);

            Window.Current.Content = newframe;
            Window.Current.Activate();
            ApplicationView.GetForCurrentView().Title = "New Page";

            NewWindowid = ApplicationView.GetForCurrentView().Id;
        });

        //Call ProjectionManager class for moving new window to secodary display
        bool available = ProjectionManager.ProjectionDisplayAvailable;

        ProjectionManager.ProjectionDisplayAvailableChanged += (s, e) =>
        {
            available = ProjectionManager.ProjectionDisplayAvailable;
        };

        await ProjectionManager.StartProjectingAsync(NewWindowid, Windowid);
    }
