XamlReader.Load 有关问题

XamlReader.Load 问题～

C# code

 Stream stream = Application.GetResourceStream(                    new StreamResourceInfo(packageStream, null),                    new Uri("AppManifest.xaml", UriKind.Relative)).Stream;            String appManifestString = new StreamReader(stream).ReadToEnd();[color=#FF0000] Deployment deployment = (Deployment)XamlReader.Load(appManifestString);[/color]

其中 appManifestString 读取有内容 为 

XAML code

<Deployment xmlns="http://schemas.microsoft.com/client/2007/deployment" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" EntryPointAssembly="Silverlightest_welcome" EntryPointType="Silverlightest_welcome.App" RuntimeVersion="2.0.31005.0">        <Deployment.Parts>               <AssemblyPart x:Name="Silverlightest_welcome" urce="Silverlightest_welcome.dll" />       </Deployment.Parts>  </Deployment>

红色的地方报错，网上搜索了下 好像是说在silverlight2正式版中，这个实现已经用不了了，关键是不能再用Deployment类来读取appManifest信息，而要自行地用XmlReader来获取。不知道该怎么解决，希望能指点下下 ^_^

[解决办法]
XamlReader对xmlns有要求，所以AppManifest.xaml是不能直接用XamlReader读取的
你可以用Deployment.Current来访问

或者你可以用下面的workaround：

C# code

            string str = @"<UserControl xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' xmlns:y='http://schemas.microsoft.com/client/2007/deployment'><UserControl.Resources><y:Deployment x:Key='manifest' EntryPointAssembly='Silverlightest_welcome' EntryPointType='Silverlightest_welcome.App' RuntimeVersion='2.0.31005.0'>        <y:Deployment.Parts>               <y:AssemblyPart x:Name='Silverlightest_welcome' Source='Silverlightest_welcome.dll' />       </y:Deployment.Parts>  </y:Deployment></UserControl.Resources></UserControl>";                        FrameworkElement obj = System.Windows.Markup.XamlReader.Load(str) as FrameworkElement;            Deployment d = obj.Resources["manifest"] as Deployment;
