Unzipping a .gz file using C#
提问by Ed.
I have a tarred gunzip file called ZippedXmls.tar.gz which has 2 xmls inside it. I need to programmatically unzip this file and the output should be 2 xmls copied in a folder.
我有一个名为 ZippedXmls.tar.gz 的 tarred gunzip 文件，其中包含 2 个 xml。我需要以编程方式解压缩此文件，输出应为复制到文件夹中的 2 个 xml。
How do I achieve this using C#?
我如何使用 C# 实现这一点？

I've used .Net's built-in GZipStreamfor gzipping byte streams and it works just fine. I suspect that your files are tarred first, before being gzipped.
我已经使用 .Net 的内置GZipStream来压缩字节流，它工作得很好。我怀疑您的文件在被 gzip 之前首先被压缩。
You've asked for code, so here's a sample, assuming you have a single file that is zipped:
您已要求提供代码，因此这里有一个示例，假设您有一个已压缩的文件：
FileStream stream = new FileStream("output.xml", FileMode.Create); // this is the output
GZipStream uncompressed = new GZipStream(stream, CompressionMode.Decompress);
uncompressed.Write(bytes,0,bytes.Length); // write all compressed bytes
uncompressed.Flush();
uncompressed.Close();
stream.Dispose();
Edit:
编辑：
You've changed your question so that the file is a tar.gz file - technically my answer is not applicable to your situation, but I'll leave it here for folks who want to handle .gz files.
您已经更改了您的问题，因此该文件是 tar.gz 文件 - 从技术上讲，我的回答不适用于您的情况，但我会将其留在这里供想要处理 .gz 文件的人使用。

I know this question is ancient, but search engines redirect here for how to extract gzip in C#, so I thought I'd provide a slightly more recent example:
我知道这个问题很古老，但是搜索引擎重定向到这里以了解如何在 C# 中提取 gzip，所以我想我会提供一个稍微更新的示例：
using (var inputFileStream = new FileStream("c:\myfile.xml.gz", FileMode.Open))
using (var gzipStream = new GZipStream(inputFileStream, CompressionMode.Decompress))
using (var outputFileStream = new FileStream("c:\myfile.xml", FileMode.Create))
{
await gzipStream.CopyToAsync(outputFileStream);
}
For what should be the simpler question of how to untar see: Decompress tar files using C#
对于如何解压缩的更简单的问题应该是什么，请参阅：Decompress tar files using C#
