Is there a reason why you can't use your colors from a resource dictionary directly like in the example shown below? For simplicity I am showing "inline" resources instead of a separate resource dictionary file. Why do you need to load your resource dictionary in code?

<Window.Resources>
    <x:Array x:Key="colors" Type="{x:Type Color}">
        <x:Static Member="Colors.White" />
        <x:Static Member="Colors.Red" />
        <x:Static Member="Colors.Green" />
        <x:Static Member="Colors.Blue" />
    </x:Array>
</Window.Resources>

<ListBox ItemsSource="{StaticResource colors}">
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <WrapPanel />
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <Rectangle Width="20" Height="20" Margin="2"
                        Stroke="Black">
                    <Rectangle.Fill>
                        <SolidColorBrush Color="{Binding}" />
                    </Rectangle.Fill>
                </Rectangle>
                <TextBlock Text="{Binding}" />
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

If you really must enumerate resources in code then I suggest you reference your resource file in your XAML and use FrameworkElement.FindResource in code-behind to get a hold of your data. In particular example from above, code might look something like:

 var colors = (IEnumerable) FindResource("colors");
 foreach(Color color in colors)
 {
    // Do something here...
 }

Thank you.I want to be able to at runtime import new themes(=resourcedictionary), and be able to edit them aswel. So I do not want to compile in my resourcefiles.

If you want to enumerate a `ResourceDictionary` at runtime, your `XamlReader.Load` approach will work well. Try this: using (var stream = new FileStream(@"path to your file", FileMode.Open)) { var resourceDictionary = (ResourceDictionary) XamlReader.Load(stream); var colors = (IEnumerable) resourceDictionary["colors"]; foreach(Color color in colors) { // ... } }

Hmm, how would you get separate items, not as part of a collection in xaml ? Have editted in an xaml example in my questionIts just that I am still wondering, in terms of my project, I can probably implement it you suggested.

Well, you can do something like this: foreach(Color color in resourceDictionary) { ... }. `ResourceDictionary` is just an `IDictionary` as well as `IEnumerable` so you can iterate over it however you like. In the code above you could extract all `Color` s from the dictionary in your original question.

In what way could I then find the key of that color ?

Sdry 2010-04-29 10:21:08

You have to be more specific in your requests. To get keys you do this: foreach(var key in resourceDictionary.Keys) { var color = resourceDictionary[key] as Color; }

foreach (System.Collections.DictionaryEntry de in ResourceDictionary) { if (de.Value is Color) { Console.WriteLine("####--->" + de.Key + " <----> " + ((Color)de.Value)); } }This is what i was looking for, sorry for the not being specific enough, your answer and comments have helped me a lot. First time using a non generic dictionary.
