我尝试了SevenZipLib和SevenZipSharp,但没有成功。
有人能给我一个使用任何免费图书馆将文本文件存档到tar.gz的工作示例吗?
我知道这不是最好的拉链方式,但这是我的要求。

NuGet中支持TAR的最受欢迎的软件包可能是SharpZipLib。其wiki包含使用tar.gz
文件的示例,包括creation。链接的示例归档整个文件夹。
要归档单个文件,可以将示例简化为:
private void CreateTarGZ(string tgzFilename, string fileName)
{
using (var outStream = File.Create(tgzFilename))
using (var gzoStream = new GZipOutputStream(outStream))
using (var tarArchive = TarArchive.CreateOutputTarArchive(gzoStream))
{
tarArchive.RootPath = Path.GetDirectoryName(fileName);
var tarEntry = TarEntry.CreateEntryFromFile(fileName);
tarEntry.Name = Path.GetFileName(fileName);
tarArchive.WriteEntry(tarEntry,true);
}
}
基本上,您需要为要存储的每个文件夹和文件创建TarEntry
。

不喜欢examples的用户如何压缩SharpZipLib提供的目录,因为它们没有将文件夹结构保留在您尝试转换为.tgz的目录中,而是使用方法复制了导致到您要压缩的任何目录。
例如:
如果您尝试压缩folderA
并且它位于//filer/folder1/
中(因此到folderA
的路径是//filer/folder1/folderA
),并且folderA
有一个文件foo.c
,然后将folderA
转换为.tgz
之后,foo.c
文件中fileA.tgz
的路径将是:
folderA.tgz/filer/folder1/foo.c
此解决方案省略了.tgz中的多余文件,从而导致:
folderA.tgz/foo.c

我还没有测试过,因为我毕竟不打算使用tar.gz文件,但看起来很彻底,人们说它有用。
