在上一篇 ^[2] 文章中，介紹了如何獲取系統 Shell 的圖示。在 C#中 呼叫 SHGetStockIconInfo 即可獲取獲取圖示

1）定義 SHGetStockIconInfo 函式用到的數據結構

publicenum SHSTOCKICONID : uint { ///<summary>Document of a type with no associated application.</summary> SIID_DOCNOASSOC = 0, ///<summary>Document of a type with an associated application.</summary> SIID_DOCASSOC = 1, ///<summary>Generic application with no custom icon.</summary> SIID_APPLICATION = 2, ///<summary>Folder (generic, unspecified state).</summary> SIID_FOLDER = 3, ///<summary>Folder (open).</summary> SIID_FOLDEROPEN = 4, ///<summary>5.25-inch disk drive.</summary> SIID_DRIVE525 = 5, ///<summary>3.5-inch disk drive.</summary> SIID_DRIVE35 = 6, ///<summary>Removable drive.</summary> SIID_DRIVEREMOVE = 7, ///<summary>Fixed drive (hard disk).</summary> SIID_DRIVEFIXED = 8, ///<summary>Network drive (connected).</summary> SIID_DRIVENET = 9, ///<summary>Network drive (disconnected).</summary> SIID_DRIVENETDISABLED = 10, ///<summary>CD drive.</summary> SIID_DRIVECD = 11, ///<summary>RAM disk drive.</summary> SIID_DRIVERAM = 12, ///<summary>The entire network.</summary> SIID_WORLD = 13, ///<summary>A computer on the network.</summary> SIID_SERVER = 15, ///<summary>A local printer or print destination.</summary> SIID_PRINTER = 16, ///<summary>The Network virtual folder (FOLDERID_NetworkFolder/CSIDL_NETWORK).</summary> SIID_MYNETWORK = 17, ///<summary>The Search feature.</summary> SIID_FIND = 22, ///<summary>The Help and Support feature.</summary> SIID_HELP = 23, ///<summary>Overlay for a shared item.</summary> SIID_SHARE = 28, ///<summary>Overlay for a shortcut.</summary> SIID_LINK = 29, ///<summary>Overlay for items that are expected to be slow to access.</summary> SIID_SLOWFILE = 30, ///<summary>The Recycle Bin (empty).</summary> SIID_RECYCLER = 31, ///<summary>The Recycle Bin (not empty).</summary> SIID_RECYCLERFULL = 32, ///<summary>Audio CD media.</summary> SIID_MEDIACDAUDIO = 40, ///<summary>Security lock.</summary> SIID_LOCK = 47, ///<summary>A virtual folder that contains the results of a search.</summary> SIID_AUTOLIST = 49, ///<summary>A network printer.</summary> SIID_PRINTERNET = 50, ///<summary>A server shared on a network.</summary> SIID_SERVERSHARE = 51, ///<summary>A local fax printer.</summary> SIID_PRINTERFAX = 52, ///<summary>A network fax printer.</summary> SIID_PRINTERFAXNET = 53, ///<summary>A file that receives the output of a Print to file operation.</summary> SIID_PRINTERFILE = 54, ///<summary>A category that results from a Stack by command to organize the contents of a folder.</summary> SIID_STACK = 55, ///<summary>Super Video CD (SVCD) media.</summary> SIID_MEDIASVCD = 56, ///<summary>A folder that contains only subfolders as child items.</summary> SIID_STUFFEDFOLDER = 57, ///<summary>Unknown drive type.</summary> SIID_DRIVEUNKNOWN = 58, ///<summary>DVD drive.</summary> SIID_DRIVEDVD = 59, ///<summary>DVD media.</summary> SIID_MEDIADVD = 60, ///<summary>DVD-RAM media.</summary> SIID_MEDIADVDRAM = 61, ///<summary>DVD-RW media.</summary> SIID_MEDIADVDRW = 62, ///<summary>DVD-R media.</summary> SIID_MEDIADVDR = 63, ///<summary>DVD-ROM media.</summary> SIID_MEDIADVDROM = 64, ///<summary>CD+ (enhanced audio CD) media.</summary> SIID_MEDIACDAUDIOPLUS = 65, ///<summary>CD-RW media.</summary> SIID_MEDIACDRW = 66, ///<summary>CD-R media.</summary> SIID_MEDIACDR = 67, ///<summary>A writable CD in the process of being burned.</summary> SIID_MEDIACDBURN = 68, ///<summary>Blank writable CD media.</summary> SIID_MEDIABLANKCD = 69, ///<summary>CD-ROM media.</summary> SIID_MEDIACDROM = 70, ///<summary>An audio file.</summary> SIID_AUDIOFILES = 71, ///<summary>An image file.</summary> SIID_IMAGEFILES = 72, ///<summary>A video file.</summary> SIID_VIDEOFILES = 73, ///<summary>A mixed file.</summary> SIID_MIXEDFILES = 74, ///<summary>Folder back.</summary> SIID_FOLDERBACK = 75, ///<summary>Folder front.</summary> SIID_FOLDERFRONT = 76, ///<summary>Security shield.

The numerical value of this flag is zero, so you always get the icon location regardless of other flags.</summary> SHGSI_ICONLOCATION = 0, ///<summary>The hIcon member of the SHSTOCKICONINFO structure receives a handle to the specified icon.</summary> SHGSI_ICON = 0x000000100, ///<summary>The iSysImageImage member of the SHSTOCKICONINFO structure receives the index of the specified icon in the system imagelist.</summary> SHGSI_SYSICONINDEX = 0x000004000, ///<summary>Modifies the SHGSI_ICON value by causing the function to add the link overlay to the file's icon.</summary> SHGSI_LINKOVERLAY = 0x000008000, ///<summary>Modifies the SHGSI_ICON value by causing the function to blend the icon with the system highlight color.</summary> SHGSI_SELECTED = 0x000010000, ///<summary>Modifies the SHGSI_ICON value by causing the function to retrieve the large version of the icon, as specified by the SM_CXICON and SM_CYICON system metrics.</summary> SHGSI_LARGEICON = 0x000000000, ///<summary>Modifies the SHGSI_ICON value by causing the function to retrieve the small version of the icon, as specified by the SM_CXSMICON and SM_CYSMICON system metrics.</summary> SHGSI_SMALLICON = 0x000000001, ///<summary>Modifies the SHGSI_LARGEICON or SHGSI_SMALLICON values by causing the function to retrieve the Shell-sized icons rather than the sizes specified by the system metrics.</summary> SHGSI_SHELLICONSIZE = 0x000000004 } [StructLayoutAttribute(LayoutKind.Sequential, CharSet = CharSet.Unicode)] publicstruct SHSTOCKICONINFO { public UInt32 cbSize; public IntPtr hIcon; public Int32 iSysIconIndex; public Int32 iIcon; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = UACIcon.MAX_PATH)] publicstring szPath; }

說明： SHSTOCKICONID 這裏實際只需要定義 SIID_SHIELD 這一個值就行了，我這裏全部貼出來了，以後需要用到的時候可以直接到這裏復制了。

2）定義 UACIcon 的類，在這個類裏封裝獲取 UAC 圖示的方法

public classUACIcon { publicconstint MAX_PATH = 260; [DllImport("Shell32.dll", SetLastError = false)] publicstaticextern Int32 SHGetStockIconInfo(SHSTOCKICONID siid, SHGSI uFlags, ref SHSTOCKICONINFO psii); [DllImport("user32.dll", SetLastError = true)] staticexternboolDestroyIcon(IntPtr hIcon); publicstatic BitmapSource GetUACIcon() { BitmapSource shieldSource = null; SHSTOCKICONINFO sii = new SHSTOCKICONINFO(); sii.cbSize = (UInt32)Marshal.SizeOf(typeof(SHSTOCKICONINFO)); Marshal.ThrowExceptionForHR(SHGetStockIconInfo(SHSTOCKICONID.SIID_SHIELD, SHGSI.SHGSI_ICON | SHGSI.SHGSI_LARGEICON, ref sii)); shieldSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHIcon( sii.hIcon, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); DestroyIcon(sii.hIcon); return shieldSource; } }

上面的程式碼中包含了從控制代碼建立 WPF ImageSource 的程式碼，如果對這一塊不了解的話，可以參考 ^[3]

3）界面 XAML 如下：

<Grid> <ButtonWidth="74"Height="28"> <Button.Content> <Grid> <Grid.ColumnDefinitions> <ColumnDefinitionWidth="32"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <ImageStretch="Uniform"x:Name="img_Icon"Width="18"Height="18"HorizontalAlignment="Right"/> <LabelContent="確認"Grid.Column="1"HorizontalAlignment="Left"/> </Grid> </Button.Content> </Button> </Grid>
