WPFによるウールガラス効果の実現

1と2は、Microsoft.WindowsAPICodePack.Shell.dllとusing System.Windows.Interopを参照する必要があり、DwmApi.dllバージョンのWindowsオペレーティングシステムでのみ使用できます.この2つの方法の共通の欠点は、フォームを起動すると点滅することです.
一、

 [StructLayout(LayoutKind.Sequential)]

        public struct MARGINS

        {

            public int cxLeftWidth;

            public int cxRightWidth;

            public int cyTopHeight;

            public int cyBottomHeight;

        };



        [DllImport("DwmApi.dll")]

        public static extern int DwmExtendFrameIntoClientArea(

            IntPtr hwnd,

            ref MARGINS pMarInset);



        private void ExtendAeroGlass(Window window)

        {

            try

            {

                //  WPF        

                IntPtr mainWindowPtr = new WindowInteropHelper(window).Handle;

                HwndSource mainWindowSrc = HwndSource.FromHwnd(mainWindowPtr);

                mainWindowSrc.CompositionTarget.BackgroundColor = Colors.Transparent;



                //   Margins

                MARGINS margins = new MARGINS();



                //   Aero Glass

                margins.cxLeftWidth = -1;

                margins.cxRightWidth = -1;

                margins.cyTopHeight = -1;

                margins.cyBottomHeight = -1;



                int hr = DwmExtendFrameIntoClientArea(mainWindowSrc.Handle, ref margins);

                if (hr < 0)

                {

                    MessageBox.Show("DwmExtendFrameIntoClientArea Failed");

                }

            }

            catch (DllNotFoundException)

            {

                Application.Current.MainWindow.Background = Brushes.White;

            }

        }

        private void Window_Loaded(object sender, RoutedEventArgs e)

        {

            this.Background = Brushes.Transparent;

            ExtendAeroGlass(this);

        }

二、

[StructLayout(LayoutKind.Sequential)]

public struct MARGINS

{

    public MARGINS(Thickness t)

    {

        Left = (int)t.Left;

        Right = (int)t.Right;

        Top = (int)t.Top;

        Bottom = (int)t.Bottom;

    }

    public int Left;

    public int Right;

    public int Top;

    public int Bottom;

}



public class GlassHelper

{

    [DllImport("dwmapi.dll", PreserveSig = false)]

    static extern void DwmExtendFrameIntoClientArea(

        IntPtr hWnd, ref MARGINS pMarInset);

    [DllImport("dwmapi.dll", PreserveSig = false)]

        static extern bool DwmIsCompositionEnabled();



    public static bool ExtendGlassFrame(Window window, Thickness margin)

    {

        if (!DwmIsCompositionEnabled())

            return false;



        IntPtr hwnd = new WindowInteropHelper(window).Handle;

        if (hwnd == IntPtr.Zero)

            throw new InvalidOperationException(

            "The Window must be shown before extending glass.");



        // Set the background to transparent from both the WPF and Win32 perspectives

        window.Background = Brushes.Transparent;

        HwndSource.FromHwnd(hwnd).CompositionTarget.BackgroundColor = Colors.Transparent;



        MARGINS margins = new MARGINS(margin);

        DwmExtendFrameIntoClientArea(hwnd, ref margins);

        return true;

    }

}



        protected override void OnSourceInitialized(EventArgs e)

        {

            base.OnSourceInitialized(e);

            GlassHelper.ExtendGlassFrame(this, new Thickness(-1));

        }

三、
この方法にはMicrosoft.Windows.Shell.dllが必要です   一閃の欠陥はない!

 xmlns:shell="clr-namespace:Microsoft.Windows.Shell;assembly=Microsoft.Windows.Shell"

<shell:WindowChrome.WindowChrome>

        <shell:WindowChrome GlassFrameThickness="-1" ResizeBorderThickness="1" 

                            CaptionHeight="15" CornerRadius="0" />

    </shell:WindowChrome.WindowChrome>

    <Window.Template>

        <ControlTemplate TargetType="{x:Type Window}">

            <Border BorderThickness="1">

                <DockPanel>

                    <Grid x:Name="WindowHeader" DockPanel.Dock="Top" Height="15">

                        <TextBlock Text="{TemplateBinding Title}"/>

                    </Grid>

                    <ContentPresenter Margin="5,5,5,5"/>

                </DockPanel>

            </Border>

        </ControlTemplate>

    </Window.Template>
