Add files to ZIP without paths, using SharpZipLib
提问by TTCG
I need to combine 3 files into 1 zip file and make it available to download for the user. I am able to achieve my requirement except one thing: it zips the files into the subfolders.
我需要将 3 个文件合并为 1 个 zip 文件，并使其可供用户下载。除了一件事之外，我能够实现我的要求：它将文件压缩到子文件夹中。
For example, my files are located like the following:
例如，我的文件位于如下位置：
C:\TTCG\WebSites\Health\ABC.CSV
C:\TTCG\WebSites\Health\XYZ.CSV
C:\TTCG\WebSites\Health3.CSV
But in the zip file, it zip the files in the folder by using "TTCG\WebSites\Health\" as the path. Please see the attach file.
但是在 zip 文件中，它使用“TTCG\WebSites\Health\”作为路径来压缩文件夹中的文件。请参阅附件。
I don't want the folders in the path. I just want 3 files in the zip file without folders. How can I achieve that?
我不想要路径中的文件夹。我只想要 zip 文件中没有文件夹的 3 个文件。我怎样才能做到这一点？
My codes to generate the zip file is as below:
我生成zip文件的代码如下：
ZipFile z = ZipFile.Create(Server.MapPath("~" + @"\Accident.zip"));
//initialize the file so that it can accept updates
z.BeginUpdate();
//add the file to the zip file
z.Add(Server.MapPath("~" + @"\ABC.csv"));
z.Add(Server.MapPath("~" + @"\XYZ.csv"));
z.Add(Server.MapPath("~" + @"3.csv"));
//commit the update once we are done
z.CommitUpdate();
//close the file
z.Close();

Based on the FAQ, you have to strip the folder path out manually:
根据常见问题解答，您必须手动删除文件夹路径：
How can I create a Zip file without folders?
Remove the path portion of the filename used to create a ZipEntry before it is added to a ZipOutputStream
ZipEntry entry = new ZipEntry(Path.GetFileName(fullPath));
如何创建没有文件夹的 Zip 文件？
删除用于创建 ZipEntry 的文件名的路径部分，然后再将其添加到 ZipOutputStream
ZipEntry entry = new ZipEntry(Path.GetFileName(fullPath));

It seems to be a limitation of the library. Hope this helps!
这似乎是图书馆的限制。希望这可以帮助！

z.Add(pathToFile, pathInZipFile);
回答by mandostroke
If you have your files in a FileSystemInfo, you can use: z.Add(file.FullName, Path.GetFileName(file.FullName));
如果您的文件在 FileSystemInfo 中，则可以使用： z.Add(file.FullName, Path.GetFileName(file.FullName));
This will add your files in the root directory of your zip.
这会将您的文件添加到 zip 的根目录中。
