在Winform和WPF中启用Aero效果
API导入：
View Code
public class DwmApi { [DllImport("dwmapi.dll", PreserveSig = false)] public static extern void DwmEnableBlurBehindWindow(IntPtr hWnd, DWM_BLURBEHIND pBlurBehind); /// <summary> /// 启用Areo效果 /// </summary> /// <param name="hWnd"></param> /// <param name="pMargins"></param> [DllImport("dwmapi.dll", PreserveSig = false)] public static extern void DwmExtendFrameIntoClientArea(IntPtr hWnd, MARGINS pMargins); /// <summary> /// 系统是否支持Areo效果 /// </summary> /// <returns></returns> [DllImport("dwmapi.dll", PreserveSig = false)] public static extern bool DwmIsCompositionEnabled(); [DllImport("dwmapi.dll", PreserveSig = false)] public static extern void DwmGetColorizationColor( out int pcrColorization, [MarshalAs(UnmanagedType.Bool)]out bool pfOpaqueBlend); [DllImport("dwmapi.dll", PreserveSig = false)] public static extern void DwmEnableComposition(bool bEnable); [DllImport("dwmapi.dll", PreserveSig = false)] public static extern IntPtr DwmRegisterThumbnail(IntPtr dest, IntPtr source); [DllImport("dwmapi.dll", PreserveSig = false)] public static extern void DwmUnregisterThumbnail(IntPtr hThumbnail); [DllImport("dwmapi.dll", PreserveSig = false)] public static extern void DwmUpdateThumbnailProperties(IntPtr hThumbnail, DWM_THUMBNAIL_PROPERTIES props); [DllImport("dwmapi.dll", PreserveSig = false)] public static extern void DwmQueryThumbnailSourceSize(IntPtr hThumbnail, out Size size); [StructLayout(LayoutKind.Sequential)] public class DWM_THUMBNAIL_PROPERTIES { public uint dwFlags; public RECT rcDestination; public RECT rcSource; public byte opacity; [MarshalAs(UnmanagedType.Bool)] public bool fVisible; [MarshalAs(UnmanagedType.Bool)] public bool fSourceClientAreaOnly; public const uint DWM_TNP_RECTDESTINATION = 0x00000001; public const uint DWM_TNP_RECTSOURCE = 0x00000002; public const uint DWM_TNP_OPACITY = 0x00000004; public const uint DWM_TNP_VISIBLE = 0x00000008; public const uint DWM_TNP_SOURCECLIENTAREAONLY = 0x00000010; } [StructLayout(LayoutKind.Sequential)] public class MARGINS { public int cxLeftWidth, cxRightWidth, cyTopHeight, cyBottomHeight; public MARGINS(int left, int top, int right, int bottom) { cxLeftWidth = left; cyTopHeight = top; cxRightWidth = right; cyBottomHeight = bottom; } } [StructLayout(LayoutKind.Sequential)] public class DWM_BLURBEHIND { public uint dwFlags; [MarshalAs(UnmanagedType.Bool)] public bool fEnable; public IntPtr hRegionBlur; [MarshalAs(UnmanagedType.Bool)] public bool fTransitionOnMaximized; public const uint DWM_BB_ENABLE = 0x00000001; public const uint DWM_BB_BLURREGION = 0x00000002; public const uint DWM_BB_TRANSITIONONMAXIMIZED = 0x00000004; } [StructLayout(LayoutKind.Sequential)] public struct RECT { public int left, top, right, bottom; public RECT(int left, int top, int right, int bottom) { this.left = left; this.top = top; this.right = right; this.bottom = bottom; } } }
在Winform中使用方法：
直接在窗体的onload事件中加入
if (DwmApi.DwmIsCompositionEnabled())
{
DwmApi.DwmExtendFrameIntoClientArea(this.Handle, new DwmApi.MARGINS(0, 0, 0, 0));
}
并重载OnPaintBackground
protected override void OnPaintBackground(PaintEventArgs e)
{
base.OnPaintBackground(e);
if (DwmApi.DwmIsCompositionEnabled())
{
e.Graphics.Clear(Color.Black);
}
}
在WPF中使用方法：
WPF无法直接得到窗体句柄，可以使用下面辅助类
View Code
class AeroHelper { public static bool ExtendGlassFrame(Window window, Thickness margin) { if (!DwmApi.DwmIsCompositionEnabled()) return false; //WPF中不能直接得到Window句柄，要借助WindowInteropHelper 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; DwmApi.MARGINS margins = new DwmApi.MARGINS((int)margin.Left, (int)margin.Top, (int)margin.Right, (int)margin.Bottom); DwmApi.DwmExtendFrameIntoClientArea(hwnd, margins); return true; } }
在Loaded事件中加入 AeroHelper.ExtendGlassFrame(this, new Thickness(-1));就可以了
