MAUI 在 Windows下,启动时全窗口最大化

当前MAUI还不完善,没有一个方便的方法做到启动时居中和启动时窗口最大化,下面是一个解决方案:

注意,以下操作是在应用的入口进行

一 添加引用

using Microsoft.Maui.LifecycleEvents;

#if WINDOWS
using Microsoft.UI;
using Microsoft.UI.Windowing;
using Windows.Graphics;
#endif

二 添加代码

#if WINDOWS
        builder.ConfigureLifecycleEvents(events =>
        {
            events.AddWindows(wndLifeCycleBuilder =>
            {
                wndLifeCycleBuilder.OnWindowCreated(window =>
                {
                    IntPtr nativeWindowHandle = WinRT.Interop.WindowNative.GetWindowHandle(window);
                    WindowId win32WindowsId = Win32Interop.GetWindowIdFromWindow(nativeWindowHandle);
                    AppWindow winuiAppWindow = AppWindow.GetFromWindowId(win32WindowsId);
                    if(winuiAppWindow.Presenter is OverlappedPresenter p)
                        p.Maximize();
                    else
                    {
                        const int width = 1200;
                        const int height = 800;
                        winuiAppWindow.MoveAndResize(new RectInt32(1920 / 2 - width / 2, 1080 / 2 - height / 2, width, height));
                    }
                });
            });
        });
#endif
