Folders

[timhargan]

When I am adding files using a stream and I want to create a folder structure of files this way there is a problem with the folders. It will create the paths in the zip file for the files but I cant get it to actually create the folder entries in the zip. How can I create the folder entry without the file system? This is an issue with opening this with other systems.

ZipFile contains a method for that.

ZipEntry zd = zf.AddDirectoryByName(folder.Path);

Then zd will allow you to set folder parameters like time and so on. When saved it will contain the folder entries in the ZIP file as expected.

I know this is old but I couldn't find this info anywhere else. If you append a DirectorySeperatorChar to the filename it will create it as an empty directory entry.

...
using (var zip = new ZipOutputStream(fileStream))
{
     if (!directoryName.EndsWith(Path.DirectorySeparatorChar.ToString()))
          directoryName += Path.DirectorySeparatorChar.ToString();

     var entry = zip.PutNextEntry(directoryName);
}
...

This issue can be closed.
