查看Wix Standard Bootstrapper应用程序的来源，似乎每个包都有 DisplayName 属性：
pPackage->sczDisplayName
但是，WiX安装项目中使用的BootstrapperCore dll没有此属性。有没有办法从托管代码中的包中提取此属性？

在构建过程中生成的BootstrapperApplicationData.xml文件放在BA .dll旁边。您可以加载该XML文件以获取有关捆绑包和捆绑包中的大量信息。
要在本机代码中加载BootstrapperApplicationData.xml，请使用随WiX工具集提供的BalManifestLoad()中的balutil.lib方法。您可以在src\ext\BalExtension\balutil\balutil.cpp中看到代码。然后，您也可以在BalInfoParseFromXml()中使用balutil.lib将XML文件解析为一堆方便的结构。您可以在src\ext\BalExtension\balutil\balinfo.cpp。
