将System.Drawing.Icon转换为System.Media.ImageSource

尝试这个：

Icon img;Bitmap bitmap = img.ToBitmap();IntPtr hBitmap = bitmap.GetHbitmap();ImageSource wpfBitmap =     Imaging.CreateBitmapSourceFromHBitmap(          hBitmap, IntPtr.Zero, Int32Rect.Empty,BitmapSizeOptions.FromEmptyOptions());

更新 ：纳入亚历克斯的建议，并将其作为扩展方法：

internal static class IconUtilities{    [Dllimport("gdi32.dll", SetLastError = true)]    private static extern bool DeleteObject(IntPtr hObject);    public static ImageSource ToImageSource(this Icon icon)    {         Bitmap bitmap = icon.ToBitmap();        IntPtr hBitmap = bitmap.GetHbitmap();        ImageSource wpfBitmap = Imaging.CreateBitmapSourceFromHBitmap( hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());        if (!DeleteObject(hBitmap))        { throw new Win32Exception();        }        return wpfBitmap;    }}

然后，您可以执行以下操作：

ImageSource wpfBitmap = img.ToImageSource();
