完美解决C#解压缩中文乱码问题
只为记录自己踩过的坑, 亲测 ! ! !项目用到的 ICSharpCode.SharpZipLib.dll最终问题定位在这里,帮助类ZipHelper里面少了句代码以下是帮助类的完整代码经过网友提问,验证出了只在NetFramework 不会乱码,NetCore依旧乱码,哪位大佬如果有其他方法,请留言更正,谢谢~最近因为公司项目,要写一个FTP自动上传 删除,下载…
要把文件夹压缩后再上传.我使用的 ICSharpCode.SharpZipLib.dll(版本:0.86.0 是在官网下载的,当然有最新的1.3.3,因为我用的是 .NetFramework 3.5)
在网上各种找帮助类Helper,最终发现压缩一会都会乱码,解决了文件名有中文乱码,但是文件夹却还是乱码,折腾了一整天, 终于找到问题所在.自己改了一下Helper, 如有问题,请各位指出.

最终问题定位在这里,帮助类ZipHelper里面少了句代码
ZipEntry ZipEntry = new ZipEntry(fileName);//因为帮助类里面少了这句代码,设置字符集,解决乱码ZipEntry.IsUnicodeText = true;
以下是帮助类的完整代码
