我已经尝试使用SevenZipLib 和 SevenZipSharp,但都没有成功。
有人能否提供一个使用任何免费库将文本文件归档到 tar.gz 的工作示例呢?
我知道这不是最好的压缩方式,但这是我的要求。

在NuGet中最受欢迎的支持TAR格式的软件包可能是SharpZipLib。它的维基页面包括使用tar.gz
文件的示例,包括创建示例。链接的示例将整个文件夹归档。
如果要对单个文件进行归档,则可以简化示例如下:
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,您需要为想要存储的每个文件和文件夹创建一个TarEntry
。我不喜欢SharpZipLib提供的有关如何压缩目录的 示例,因为它们的方法并未保留要转换为 .tgz 的目录中的文件夹结构,而是复制了通往该目录的文件夹路径。
例如:
如果您要压缩位于//filer/folder1/folderA
的folderA
(其中包含一个名为foo.c
的单个文件),那么在将folderA
转换成.tgz
后,在 .tgz 文件中,foo.c
所在的路径将是:
folderA.tgz/filer/folder1/foo.c
folderA.tgz/foo.c
