通过DotNetZip库以编程方式提取ZIP文件？ [英] Extract a ZIP file programmatically by DotNetZip library?

问题描述

我有一个获取ZIP文件并将其提取到目录
中的函数（我使用 DotNetZip 库。）

I have a function that get a ZIP file and extract it to a directory (I use DotNetZip library.)

public void ExtractFileToDirectory(string zipFileName, string outputDirectory)
{
     ZipFile zip = ZipFile.Read(zipFileName);
     Directory.CreateDirectory(outputDirectory);
     zip.ExtractAll(outputDirectory,ExtractExistingFileAction.OverwriteSilently);
}

我的ZIP文件包含多个文件和目录。但是我只想提取其中一些文件中的
，而不是全部。

My ZIP file contains multiple files and directories. But I want to extract only some of these files, not all of them.

我如何进行这项工作？

推荐答案

您需要测试每个 ZipEntry 以查看是否要提取它：

You need to test each ZipEntry to see if you want to extract it:

public void ExtractFileToDirectory(string zipFileName, string outputDirectory)
{
     ZipFile zip = ZipFile.Read(zipFileName);
     Directory.CreateDirectory(outputDirectory);
      foreach (ZipEntry e in zip)
      {
        // check if you want to extract e or not
        if(e.FileName == "TheFileToExtract") 
          e.Extract(outputDirectory, ExtractExistingFileAction.OverwriteSilently);
      }
}

。

ZipFile zip = ZipFile.Read(zipFileName); //Runs in framework 4.5
