使用Paul Ingles的此
CodeProject文章中的
GetFileIcon方法，并作为参数传递。
.ext``name
该
GetFileIcon方法是对本机的包装，
SHGetFileInfo并在此处复制以用于说明：
public static System.Drawing.Icon GetFileIcon(string name, IconSize size, bool linkOverlay){ Shell32.SHFILEINFO shfi = new Shell32.SHFILEINFO(); uint flags = Shell32.SHGFI_ICON | Shell32.SHGFI_USEFILEATTRIBUTES; if (true == linkOverlay) flags += Shell32.SHGFI_linkOVERLAY; if (IconSize.Small == size) { flags += Shell32.SHGFI_SMALLICON ; // include the small icon flag } else { flags += Shell32.SHGFI_LARGEICON ; // include the large icon flag } Shell32.SHGetFileInfo( name, Shell32.FILE_ATTRIBUTE_NORMAL, ref shfi, (uint) System.Runtime.InteropServices.Marshal.SizeOf(shfi), flags ); // Copy (clone) the returned icon to a new object, thus allowing us // to call DestroyIcon immediately System.Drawing.Icon icon = (System.Drawing.Icon) System.Drawing.Icon.FromHandle(shfi.hIcon).Clone(); User32.DestroyIcon( shfi.hIcon ); // Cleanup return icon;}
