以下代码使用我们的 Rebex ZIP 并展示如何在不使用任何临时文件的情况下将文件添加到 ZIP 存档中文件。然后将该 ZIP 发送到 Web 浏览器。

// prepare MemoryStream to create ZIP archive within
using (MemoryStream ms = new MemoryStream())
{
    // create new ZIP archive within prepared MemoryStream
    using (ZipArchive zip = new ZipArchive(ms))
    {            
         // add some files to ZIP archive
         zip.Add(@"c:\temp\testfile.txt");
         zip.Add(@"c:\temp\innerfile.txt", @"\subfolder");

         // clear response stream and set the response header and content type
         Response.Clear();
         Response.ContentType = "application/zip";
         Response.AddHeader("content-disposition", "filename=sample.zip");

         // write content of the MemoryStream (created ZIP archive) 
         // to the response stream
         ms.WriteTo(Response.OutputStream);
    }
}

// close the current HTTP response and stop executing this page
HttpContext.Current.ApplicationInstance.CompleteRequest();

替代解决方案：

SharpZipLib 和 DotNetZip 广泛使用的免费替代品。

Following code uses our Rebex ZIP and shows how to add files into the ZIP archive without using any temp file. The ZIP is then sent to the web browser.

// prepare MemoryStream to create ZIP archive within
using (MemoryStream ms = new MemoryStream())
{
    // create new ZIP archive within prepared MemoryStream
    using (ZipArchive zip = new ZipArchive(ms))
    {            
         // add some files to ZIP archive
         zip.Add(@"c:\temp\testfile.txt");
         zip.Add(@"c:\temp\innerfile.txt", @"\subfolder");

         // clear response stream and set the response header and content type
         Response.Clear();
         Response.ContentType = "application/zip";
         Response.AddHeader("content-disposition", "filename=sample.zip");

         // write content of the MemoryStream (created ZIP archive) 
         // to the response stream
         ms.WriteTo(Response.OutputStream);
    }
}

// close the current HTTP response and stop executing this page
HttpContext.Current.ApplicationInstance.CompleteRequest();
