Is there any way to access app.xaml resources of an imported XA开发者_如何学PythonP file (from host silverlight app) ???

Or better, import guest app.xaml into Host app.xaml

Problem is that in the imported Silverlight application, I lost all app.xaml resources, and I just see host resources... I would like to merge them...

It's possible?

I load XAP in this way

private void wc_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
    var manifestStream = Application.GetResourceStream(
        new StreamResourceInfo(e.Result, null),
        new Uri("AppManifest.xaml", UriKind.Relative));

    string appManifest = new StreamReader(manifestStream.Stream).ReadToEnd();
    string assemblyName =m_rootAssembly + ".dll";
    XmlReader reader = XmlReader.Create(new StringReader(appManifest));
    Assembly asm = null;
    while (reader.Read())
    {
        if (reader.IsStartElement("AssemblyPart"))
        {
            reader.MoveToAttribute("Source");
            reader.ReadAttributeValue();
            if (reader.Value == assemblyName)
            {
                var assemblyStream = new StreamResourceInfo(e.Result, "application/binary");
                var si = Application.GetResourceStream(assemblyStream, new Uri(reader.Value, UriKind.Relative));
                AssemblyPart p = new AssemblyPart();
                asm = p.Load(si.Stream);
                break;
            }
        }
    }

    if (asm == null)
        throw new InvalidOperationException("Could not find specified assembly.");

    var o = asm.CreateInstance(m_typeName);
    if (o == null)
        throw new InvalidOperationException("Could not create instance of requested type.");

    RaiseXapLoadedEvent(o);
}


if you know the uri of the resource file, like: "/COMPONENTNAME;component/resourcepath.xaml",

you can simply add this resource dictionary to your application by writing codes like: Application.Current.Resources.MergedDictionaries.Add("*resourceuri*");

the "Application.Current" always points to the runtime application instance (host application), no matter where it is used.
