c# - DotNetZip 从 MemoryStream 打开 zip 文件

Question

我喜欢做的不是在磁盘上存储 zip 文件，而是喜欢从 MemoryStream 打开它。

我正在查看 DotNetZip 编程示例的文档:请注意，我根据我认为可能需要的内容对其进行了微调。

    var ms = new MemoryStream();
    using (ZipFile zip = new ZipFile())
    {
       zip.AddFile("ReadMe.txt");
       zip.AddFile("7440-N49th.png");
       zip.AddFile("2008_Annual_Report.pdf");        
       zip.Save(ms); // this will save the files in memory steam
    }


  // now what I need is for the zip file to open up so that 
     the user can view all the files in it. Not sure what to do next after 
     zip.Save(ms) for this to happen.

试试这个:

public ActionResult Index()
{
    var memoryStream = new MemoryStream();

    using (var zip = new ZipFile())
    {
        zip.AddFile("ReadMe.txt");
        zip.AddFile("7440-N49th.png");
        zip.AddFile("2008_Annual_Report.pdf"); 
        zip.Save(memoryStream);
    }

    memoryStream.Seek(0, 0);
    return File(memoryStream, "application/octet-stream", "archive.zip");
}
