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

1）定義SHGetStockIconInfo函數用到的數據結構

 }

 [Flags]
public enum SHGSI : uint
 {
/// <summary>The szPath and iIcon members of the SHSTOCKICONINFO structure receive the path and icon index of the requested icon, in a format suitable for passing to the ExtractIcon function.

 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,

 SHGSI_SHELLICONSIZE=0x000000004
 }

 [StructLayoutAttribute(LayoutKind.Sequential, CharSet=CharSet.Unicode)]
public struct SHSTOCKICONINFO
 {
public UInt32 cbSize;
public IntPtr hIcon;
public Int32 iSysIconIndex;
public Int32 iIcon;
 [MarshalAs(UnmanagedType.ByValTStr, SizeConst=UACIcon.MAX_PATH)]
public string szPath;
 }

說明：SHSTOCKICONID這里實際只需要定義SIID_SHIELD這一個值就行了，我這里全部貼出來了，以后需要用到的時候可以直接到這里復制了。

2）定義UACIcon的類，在這個類里封裝獲取UAC圖標的方法

public class UACIcon
 {
public const int MAX_PATH=260;

 [DllImport("Shell32.dll", SetLastError=false)]
public static extern Int32 SHGetStockIconInfo(SHSTOCKICONID siid, SHGSI uFlags, ref SHSTOCKICONINFO psii);

 [DllImport("user32.dll", SetLastError=true)]
static extern bool DestroyIcon(IntPtr hIcon);

public static BitmapSource GetUACIcon()
 {
 BitmapSource shieldSource=;

 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;
 }
 }

上面的代碼中包含了從句柄創建WPF ImageSource的代碼，如果對這一塊不了解的話，可以參考^[3]

3）界面XAML如下：

<Grid>
<Button Width="74" Height="28">
<Button.Content>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="32"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>

<Image Stretch="Uniform" x:Name="img_Icon" Width="18" Height="18" HorizontalAlignment="Right"/>
<Label Content="確認" Grid.Column="1" HorizontalAlignment="Left"/>
</Grid>
</Button.Content>
</Button>
</Grid>

4）加載圖標

public partial class MainWindow : Window
 {
public MainWindow()
 {
 InitializeComponent();
this.img_Icon.Source=UACIcon.GetUACIcon();
 }
 }

運行效果：
