如何从UserControl的外部Window继承资源？

Question

I start my WPF app per Windows Application new Application().Run(new MainWindow()) - so I don't have an app.xaml

I have a main window, which contains any used UserControls per ContentControl

<Window ..>
    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="..." />
                <!-- ... -->
            <converter:BooleanToIntConverter x:Key="BooleanToIntConverter" />
        </ResourceDictionary>
    </Window.Resources>

    <ContentControl Grid.Column="0" Content="{Binding MyUserControl}" />
</Window>

How can I inherit resources from my MainWindow to UserControls which are within iny MainWindow?

Answer 1

You can set the resources of the Application by accessing the Resources ResourceDictionary :

Application app = new Application();
app.Resources["MySharedResource"] = ...;
app.Resources["MyOtherSharedResource"] = ...;
app.Run(new MainWindow());

This is exactly what is done with the App.xaml file.
