C#中,上传apk时,怎样获取apk的基本信息

Answer 1

安卓的APK么？

安卓的APK是个压缩包格式，我给你个思路 具体代码你去写 还是比较简单的

分为两步：
①上传按钮点击时解压APK压缩包
②获取压缩包内AndroidManifest.xml（apk的包名，版本号，版本名称都在此XML文件内）
③解析这个XML

既然答了 我就完善一下：（在codeplex上面找到的）

追问

using AndroidXml;
在哪下载啊，我下载下来是错的

var reader = new AndroidXmlReader(stream);报错

C#通过调用aapt获取apk文件的包名等信息
