獲取顯示名稱從包ID

Question

通過維克斯標準引導程序應用的源尋找，似乎每個包具有DisplayName的屬性：

pPackage->sczDisplayName 

然而，在維克斯安裝中使用的BootstrapperCore DLL項目沒有這個屬性。有什麼辦法從託管代碼中的捆綁中提取此屬性？

構建過程中生成的BootstrapperApplicationData.xml文件放在您的BA .dll旁邊。您可以加載該XML文件以獲取有關捆綁軟件包和軟件包的大量信息。

要使用本機代碼加載BootstrapperApplicationData.xml，請使用隨WiX工具集提供的balutil.lib中的BalManifestLoad()方法。您可以在src\ext\BalExtension\balutil\balutil.cpp中看到代碼。然後，您也可以在balutil.lib中使用BalInfoParseFromXml()將XML文件解析爲一堆方便的結構。您可以在src\ext\BalExtension\balutil\balinfo.cpp中看到代碼。
