GetHatchBrush

Case

first create ObjectProvider in App.xaml xmlns:sys="clr-namespace:System;assembly=mscorlib"

 <ObjectDataProvider x:Key="HatchStyles" MethodName="GetValues" ObjectType="sys:Enum">
	                <ObjectDataProvider.MethodParameters>
	                    <x:Type Type="hc:HatchStyle"/>
	                </ObjectDataProvider.MethodParameters>
</ObjectDataProvider>

then create a HatchBrushConverter converter

public class HatchBrushConverter : IValueConverter
	    {
	        private readonly HatchBrushGenerator _brushGenerator;
	
	        public HatchBrushConverter()
	        {
	            _brushGenerator = new HatchBrushGenerator();
	        }
	
	        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
	        {
	            if (value is HatchStyle style)
	            {
	                return _brushGenerator.GetHatchBrush(style, ResourceHelper.GetResource<Color>("DarkPrimaryColor"), ResourceHelper.GetResource<Color>("BackgroundColor"));
	            }
	            return Brushes.Transparent;
	        }
	
	        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
	        {
	            throw new NotImplementedException();
	        }
	    }

now you can use hatch

 <Border Style="{StaticResource BorderRegion}" Margin="32" Background="{Binding SelectedValue,ElementName=ComboBoxDemo,Converter={StaticResource HatchBrushConverter}}">
	            <ComboBox SelectedIndex="0" VerticalAlignment="Center" Name="ComboBoxDemo" Width="180" ItemsSource="{Binding Source={StaticResource HatchStyles}}"/>
	        </Border>
