如何使用ZipOutputStream在zip文件中添加EmptyFolder或目录

Question

我希望能够使用ICSharpCode.SharpZipLib.Zip.ZipOutputStream创建包含空文件夹的zip文件。我可以使用ICSharpCode.SharpZipLib.Zip.FastZip.CreateEmptyDirectories = true，但FastZip不允许使用UTF8文件名。

我知道这已经很老了，但我遇到了同样的问题（使用ZipOutputStream压缩空目录）。

我正在根据不同的父目录进行递归调用。

public void CompressFolder(string path, ZipOutputStream zipStream, int folderOffset)
    {
        var files = Directory.GetFiles(path);
        var directories = Directory.GetDirectories(path);

        //this is where I add the empty directory
        //code begin
        if (files.Count() == 0 && directories.Count() == 0)
        {
            DirectoryInfo di = new DirectoryInfo(path);
            string cleanName = ZipEntry.CleanName(path.Substring(folderOffset)) + "/";
            ZipEntry zipEntry = new ZipEntry(cleanName);
            zipEntry.DateTime = di.LastWriteTime;
            zipStream.PutNextEntry(zipEntry);
            zipStream.CloseEntry();
            return;
        }
        //code end

        foreach (string file in files)
        {
            FileInfo fileInfo = new FileInfo(file);
            string cleanName = ZipEntry.CleanName(file.Substring(folderOffset));
            ZipEntry zipEntry = new ZipEntry(cleanName);
            zipEntry.DateTime = fileInfo.LastWriteTime;
            zipEntry.Size = fileInfo.Length;
            zipStream.PutNextEntry(zipEntry);
            byte[] numArray = new byte[4096];
            using (FileStream fileStream = File.OpenRead(file))
            {
                StreamUtils.Copy(fileStream, zipStream, numArray);
            }
            zipStream.CloseEntry();
        }

        foreach (string directory in directories)
        {
            CompressFolder(directory, zipStream, folderOffset);
        }
    }

请参阅http://community.sharpdevelop.net/forums/p/10856/29901.aspx其中（我引用）： “我们当前的路线图包括UTF条目文件名处理[...]” 这将使我了解目前不支持UTF文件名。
