ASP.NET下载所有的文件邮编 [英] ASP.NET Download All Files as Zip

问题描述

我有一个文件夹中，有数以百计的MP3文件在它我的Web服务器上。我想提供的选项为用户从网页上下载每个MP3的压缩文档的目录。

I have a folder on my web server that has hundreds of mp3 files in it. I would like to provide the option for a user to download a zipped archive of every mp3 in the directory from a web page.

我想COM preSS编程仅在需要时的文件。因为zip文件将是相当大的，我想，我需要将zip文件发送到响应流中的因为它是被压缩，出于性能的考虑。

I want to compress the files programmatically only when needed. Because the zip file will be quite large, I am thinking that I will need to send the zip file to the response stream as it is being zipped, for performance reasons.

这可能吗？我该怎么办呢？

Is this possible? How can I do it?

推荐答案

下面是code我用用DotNetZip做到这一点 - 工作得非常好。很显然，您需要提供变量ou​​tputFileName，夹folderName和includeSubFolders。

Here is code I use to do this with DotNetZip - works very well. Obviously you will need to provide the variables for outputFileName, folderName, and includeSubFolders.

response.ContentType = "application/zip";
response.AddHeader("content-disposition", "attachment; filename=" + outputFileName);
using (ZipFile zipfile = new ZipFile()) {
  zipfile.AddSelectedFiles("*.*", folderName, includeSubFolders);
  zipfile.Save(response.OutputStream);
}
