WPF 几行代码实现窗体毛玻璃效果（Aero Glass）

创建一个叫AeroGlass.cs 的类，代码如下：

using System;
using System.Runtime.InteropServices;
using System.Windows;
using System.Windows.Interop;
using System.Windows.Media;

[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;
}
}

把这段代码加到主窗体就可以了！

protected override void OnSourceInitialized(EventArgs e)

{

base.OnSourceInitialized(e);

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

}
