How to render DrawingBrush elements in ResourceDictionary in WPF?

Question

I have a Xaml like the shown below. I have generated the Xaml from an emf file in expression. I need to enumerate and render the DrawingBrush elements. How can I accomplish that? Thanks!

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<DrawingBrush x:Key="UnnamedObject0" Stretch="Uniform">

                    <GeometryDrawing.Pen>
                        <Pen Thickness="0.97367" StartLineCap="Round" EndLineCap="Round" LineJoin="Round" Brush="#FF000000"/>
                    </GeometryDrawing.Pen>

</ResourceDictionary>

Answer 1

You could use an ItemsControl and bind a list of the DrawingBrush from the ResourceDictionary

Example:

Xaml:

<Window x:Class="WpfApplication8.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow"  Name="UI" Width="262" Height="318">

    <Grid DataContext="{Binding ElementName=UI}">
        <ItemsControl ItemsSource="{Binding Visuals}">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <Rectangle Width="200" Height="200" Fill="{Binding}" />
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </Grid>
</Window>

Code:

namespace WpfApplication8
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        // Application Resources or any other ResourceDictionary
        public IEnumerable<DrawingBrush> Visuals
        {
            get { return Application.Current.Resources.Values.OfType<DrawingBrush>(); }
        }
    }
}

Result:

---

Edit:

If you are using MergedDictionaries you can use

public IEnumerable<DrawingBrush> Visuals
{
    get { return Application.Current.Resources.MergedDictionaries.SelectMany(r => r.Values.OfType<DrawingBrush>()); }
}
