這些技術在上一篇文章的介紹的軟件里有用到，現在單獨摘出來說明一下。

添加 using System.Runtime.InteropServices;

[StructLayout(LayoutKind.Sequential)]
public struct MARGINS
{
public int cxLeftWidth;
public int cxRightWidth;
public int cyTopHeight;
public int cyBottomHeight;
}
#region 引用 Dll
[DllImport("DwmApi.dll")] //玻璃
public static extern int DwmExtendFrameIntoClientArea(IntPtr hwnd, ref MARGINS pMarInset);
[DllImport("user32.dll", EntryPoint = "SendMessage")]// 移動
public static extern int SendMessage(int hWnd, int wMsg, int wParam, int lParam);
[DllImport("user32.dll", EntryPoint = "ReleaseCapture")]
public static extern int ReleaseCapture();
public const int WM_SysCommand = 0x0112;
public const int SC_MOVE = 0xF012;

#endregion

public MainWindow()
{
InitializeComponent();

this.Background = Brushes.Transparent;
ExtendAeroGlass(this);

}

private void ExtendAeroGlass(Window window)
{
try
{
// 為WPF程序獲取窗口句柄
IntPtr mainWindowPtr = new WindowInteropHelper(window).Handle;
HwndSource mainWindowSrc = HwndSource.FromHwnd(mainWindowPtr);
mainWindowSrc.CompositionTarget.BackgroundColor = Colors.Transparent;
// 設置Margins
MARGINS margins = new MARGINS();

// 擴展Aero Glass
margins.cxLeftWidth = -1;
margins.cxRightWidth = -1;
margins.cyTopHeight = -1;
margins.cyBottomHeight = -1;

int hr = DwmExtendFrameIntoClientArea(mainWindowSrc.Handle, ref margins);
if (hr < 0)
{
checkBox1.IsChecked = false;
MessageBox.Show("玻璃效果加載失敗！");
}
}
catch (DllNotFoundException)
{
Application.Current.MainWindow.Background = Brushes.White;
}
}
private void Window_MouseDown(object sender, MouseButtonEventArgs e) //鼠標按下時，移動
{
IntPtr mainWindowPtr = new WindowInteropHelper(this).Handle;
HwndSource mainWindowSrc = HwndSource.FromHwnd(mainWindowPtr);
ReleaseCapture();
SendMessage(mainWindowSrc.Handle.ToInt32(), WM_SysCommand, SC_MOVE, 0);
}

完成 。。
