System.IO.Compression is an official release of a decompression toolkit that defaults to using UTF-8 encoding for decompressing files. However, on Windows, encoding can be quite chaotic; if files or directories have Chinese names, decompressed results may be g…
System.IO.Compression 是官方发布的一个由于解压缩的工具包,默认使用 utf8 编码解压缩文件。 但是在 Windows 上,编码比较混乱,如果文件或目录是中文名称,那么解压后会出现乱码,即使压缩包都是 UTF8 编码,.NET 解压也会出现乱码问题,所以需要使用 GB2312 编码解压。 但是 .NET 中默认是不包含 GB2312 编码的。 笔者说的不一定对,可能跟压缩文件也有关,总之, .NET 默认不支持 GB2312 编码,导致解压后中文文件名称乱码。 首先引入 System.Text…
