[UWP] 프로그램 실행 시 화면의 크기를 최대화하는 방법

• 프로그램을 작성하여 운용할 때 실행창을 곧바로 최대화해야 할 상황이 올 수 있다.

 

<MainPage.xaml.cs>

namespace TestProject
{
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            MaximizePageOnLoad();
            this.InitializeComponent();
        }

        void MaximizePageOnLoad()
        {
            var page = DisplayInformation.GetForCurrentView();

            // 화면 해상도를 얻어온다
            var page_resolution = new Size(page.ScreenWidthInRawPixels, page.ScreenHeightInRawPixels);

            // 유효한 픽셀단위로 화면 크기를 계산한다..
            var page_scale = page.ResolutionScale == ResolutionScale.Invalid ? 1 : page.RawPixelsPerViewPixel;
            var page_bounds = new Size(page_resolution.Width / page_scale, page_resolution.Height / page_scale);

            ApplicationView.PreferredLaunchViewSize = new Size(page_bounds.Width, page_bounds.Height);
            ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.PreferredLaunchViewSize;
        }
    }
}
