如何使用 ICSharpCode.SharpZipLib 将文件夹添加到 zip 存档中

我必须在以编程方式创建的 zip 文件内创建两个文件夹ICSharpCode.SharZipLib.Zip。我想要：

    private void AddToZipStream(byte[] inputStream, ZipOutputStream zipStream, string fileName, string fileExtension)
    {
        var courseName = RemoveSpecialCharacters(fileName);

        var m_Bytes = inputStream;
        if ((m_Bytes != null) && (zipStream != null))
        {
            var newEntry = new ZipEntry(ZipEntry.CleanName(string.Concat(courseName, fileExtension)));
            newEntry.DateTime = DateTime.Now;
            newEntry.Size = m_Bytes.Length;

            zipStream.PutNextEntry(newEntry);
            zipStream.Write(m_Bytes, 0, m_Bytes.Length);
            zipStream.CloseEntry();
            zipStream.UseZip64 = UseZip64.Off;
        }
    }

如何使用创建目录ZipEntry以及如何将文件添加到位于内部的目录中Zip档案？

我想到了：

• 你可以简单地做new ZipEntry("Folder1/Archive.txt"); and new ZipEntry("Folder2/Archive2.txt");
