Silverlight從動態XAP加載導入App.xaml

Question

有什么方法（從主機silverlight應用程序）訪問導入的XAP文件的app.xaml資源？

或者更好的是，將來賓app.xaml導入主機app.xaml

問題是在導入的Silverlight應用程序中，我丟失了所有app.xaml資源，而我只看到主機資源...我想將它們合並...

這是可能的？

我以這種方式加載XAP

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);
}

如果您知道資源文件的uri，例如：“ / COMPONENTNAME ; component / resourcepath .xaml”，

您只需編寫以下代碼即可將此資源字典添加到您的應用程序中： Application.Current.Resources.MergedDictionaries.Add("*resourceuri*");

無論在何處使用，“ Application.Current”始終指向運行時應用程序實例（主機應用程序）。
