Question

I have some images added to Properties.Resources, where I can access them like:

Properties.Resources.LayerIcon;

and want to use it in Xaml, but don’t know how to do this.

I know there are different ways for images to be added into a WPF project, but I need to use Properties.Resources, because that’s the only way I found where the images show up, when the application is launched via reflection.

The images in Properties.Resources are of type System.Drawing.Bitmap, but WPF uses System.Windows.Media.ImageSource. You can create a converter:

[ValueConversion(typeof(System.Drawing.Bitmap), typeof(ImageSource))]
public class BitmapToImageSourceConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        var bmp = value as System.Drawing.Bitmap;
        if (bmp == null)
            return null;
        return System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
                    bmp.GetHbitmap(),
                    IntPtr.Zero,
                    Int32Rect.Empty,
                    BitmapSizeOptions.FromEmptyOptions());
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}

And use it as follows:

<Image Source="{Binding Source={x:Static prop:Resources.LayerIcon}, Converter={StaticResource bitmapToImageSourceConverter}}" />

Make sure your Resource is set to public and not internal.
