分析原因
利用ICSharpCode.SharpZipLib.dll解析APK时，进入APK的AndroidXml获取时出现报错
出错代码
using (ICSharpCode.SharpZipLib.Zip.ZipInputStream zip = new ICSharpCode.SharpZipLib.Zip.ZipInputStream(File.OpenRead(path)))
{
using (var filestream = new FileStream(path, FileMode.Open, FileAccess.Read))
{
ICSharpCode.SharpZipLib.Zip.ZipFile zipfile = new ICSharpCode.SharpZipLib.Zip.ZipFile(filestream);
ICSharpCode.SharpZipLib.Zip.ZipEntry item;
// 出错部分
while ((item = zip.GetNextEntry()) != null)
{
if (item.Name.ToLower() == "androidmanifest.xml")
{
manifestData = new byte[50 * 1024];
using (Stream strm = zipfile.GetInputStream(item))
{
strm.Read(manifestData, 0, manifestData.Length);
}
}
if (item.Name.ToLower() == "resources.arsc")
{
using (Stream strm = zipfile.GetInputStream(item))
{
using (BinaryReader s = new BinaryReader(strm))
{
resourcesData = s.ReadBytes((int)s.BaseStream.Length);
}
}
}
}
}
解决方法
经过查阅资料，解决方法如下
using (ZipInputStream zip = new ZipInputStream(File.OpenRead(path)))
{
using (var filestream = new FileStream(path, FileMode.Open, FileAccess.Read))
{
System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);
ZipFile zipfile = new ZipFile(filestream);
// 代码更换部分
foreach (ZipEntry entry in zipfile)
{
if (entry != null)
{
if (entry.Name.ToLower() == "androidmanifest.xml")
{
manifestData = new byte[50 * 1024];
Stream strm = zipfile.GetInputStream(entry);
strm.Read(manifestData, 0, manifestData.Length);
}
if (entry.Name.ToLower() == "resources.arsc")
{
Stream strm = zipfile.GetInputStream(entry);
using (BinaryReader s = new BinaryReader(strm))
{
resourcesData = s.ReadBytes((int)entry.Size);
}
}
}
}
}
}
