在运行时检查Windows应用程序AppxManifest

Question

我试着在运行时加载AppxManifest来读取应用程序的版本。我喜欢这篇文章：http://tonychampion.net/blog/index.php/2013/01/examining-the-windows-store-apps-appxmanifest-at-runtime/#comments

我试着从邮局接电话：

var doc = XDocument.Load("AppxManifest.xml", LoadOptions.None);

但是这会抛出以下异常：

{System.Xml.XmlException: An internal error has occurred.
   at System.Xml.XmlXapResolver.GetEntity(Uri absoluteUri, String role, Type ofObjectToReturn)
   at System.Xml.XmlTextReaderImpl.FinishInitUriString()
   at System.Xml.XmlTextReaderImpl..ctor(String uriStr, XmlReaderSettings settings, XmlParserContext context, XmlResolver uriResolver)
   at System.Xml.XmlReaderSettings.CreateReader(String inputUri, XmlParserContext inputContext)
   at System.Xml.XmlReader.Create(String inputUri, XmlReaderSettings settings, XmlParserContext inputContext)
   at System.Xml.Linq.XDocument.Load(String uri, LoadOptions options)
   at MyMedi.Src.Utilities.GetVersion()
   at MyMedi.WindowsPhone.Test.Src.UtilitiesTest.Utilities_GetVersionTest()}

有人能告诉我我做错了什么吗？

谢谢NPadrutt

我不知道您为什么要这样做，但是您可以尝试在文件引用中加载带有ms-appx:// uri模式的文档。

不过，有一个更容易的方法来实现你的目标。

Package package = Package.Current;
PackageId packageId = package.Id;
PackageVersion version = packageId.Version;

var versionString = string.Format(
               CultureInfo.InvariantCulture,
               "{0}.{1}.{2}.{3}",
               version.Major,
               version.Minor,
               version.Build,
               version.Revision);
