分析原因
利用ICSharpCode.SharpZipLib.Zip进行APK解析时，因为APK内编译的名称为中文，查询微软开发文档936为gb2312中文编码

代码语言：c#复制// 错误代码
using (ZipInputStream zip = new ZipInputStream(File.OpenRead(path)))
{
using (var filestream = new FileStream(path, FileMode.Open, FileAccess.Read))
{
// 出现错误部分
ZipFile zipfile = new ZipFile(filestream);
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);
}

Stream strm = zipfile.GetInputStream(entry);
using (BinaryReader s = new BinaryReader(strm))
{
resourcesData = s.ReadBytes((int)entry.Size);
}

// 解决方法
using (ZipInputStream zip = new ZipInputStream(File.OpenRead(path)))
{
using (var filestream = new FileStream(path, FileMode.Open, FileAccess.Read))
{
// 在.Net Core中默认System.Text中不支持CodePagesEncodingProvider.Instance
// 添加下方这行代码允许访问.Net Framework平台上不支持的编码提供程序
System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);
ZipFile zipfile = new ZipFile(filestream);
