Creating virtual directory tree in zip file using dotnetzip

Question

I am trying to create a zip file from code, I'm using dotnetzip

I want to create a directory tree in the folder that doesn't exist on disk. How do I do this?

I have tried using AddDirectory but this seems to want to find the directory on disk. I have also tried AddEntry but this requires some content.

My files are stored in a SQL Server using the FileStream option and organised in a hierarchy there.

I wrote this recursive method to do it but the AddDirectory line doesn't work.

    private void GetFiles(ZipFile zipFile, Folder folder, string path)
    {
        zipFile.AddDirectory(folder.FolderName, path);

        foreach (var file in folder.Files)
            zipFile.AddEntry(file.FileName, file.FileData);

        foreach(var subfolder in folder.SubFolders)
        {
            GetFiles(zipFile, subfolder, path + "\\" + subfolder.FolderName);
        }
    }

You can use AddDirectoryByName to create a new directory in the zipfile instead of importing a directory
