//压缩 string fromFileDirectory = @"C:\test\我是目录"; string outFilePath = @"C:\压缩包1.zip"; CompressHelper.ZipCompress(fromFileDirectory, outFilePath);   //解压缩 string fromFilePath = @"C:\压缩包1.zip"; string outFileDirectory = @"C:\解压目录\压缩包1"; CompressHelper.Decompress(fromFilePath, outFileDirectory);

五.中文乱码问题

老版本直接加入下面一行代码就可以了

SharpCompress.Common.ArchiveEncoding.Default = Encoding.GetEncoding ("utf-8");

但是我使用的是0.23.0版本，.ArchiveEncoding已经从静态类改为普通类了，无法这样调用

参考：https://github.com/adamhathcock/sharpcompress/issues/268

 

 最后发现：ArchiveEncoding类是OptionsBase的属性，而OptionsBase是WriterOptions的基类，ZipArchive的SaveTo方法带WriterOptions参数，那就ok了
