使用复选框列表下载多个文件 [英] Downloading Multiple files using checkbox list

问题描述

我试图使用复选框列表一次从目录列表中下载多个文件.文件名成功显示在列表中，但下载后...该文件夹为空..
以下是填充复选框列表的代码:

Im trying to download multiple files at onces from the directory list using a checkboxlist.The filename successfully appears on the list but upon downloading ...the folder is empty..
Below isthe code to populate the checkboxlist:

string[] files = Directory.GetFiles(Server.MapPath(".") + @"\NewFolder1");


                    chklist.Items.Clear();
                    foreach (string file in files)
                    {

                        chklist.Items.Add(new ListItem(Path.GetFileName(file), file));

                    }

在btndownload下，我有..

Under the btndownload i have..

Response.Clear();

            Response.ContentType = "application/zip";

            Response.AddHeader("content-disposition", "filename=" + "Album.zip");



            using (ZipFile zip = new ZipFile())
            {

                foreach (ListItem item in chklist.Items)
                {

                    if (item.Selected)
                    {

                        zip.AddFile(item.Value, "Album");

                    }

                }

                zip.Save(Response.OutputStream);

任何出现错误的项目..或者任何人都可以纠正我

推荐答案

您正在用C ++编写网页吗?你最近怎么样?

正如我昨天告诉您的那样，您需要进行一些调试以弄清楚为什么您的zip文件为空.奇怪的原因是您要从一个空文件夹中压缩文件.不要再问同样的事情，尤其是在没有实际执行我们告诉您的操作的情况下.

You''re writing a web page with C++ ? How are you doing that ?

As I told you yesterday, you need to do some debugging to work out why your zip is empty. The odds are the reason is that you''re zipping files from an empty folder. Don''t ask the same thing again, esp without actually doing what we told you to do.
