But it is not allowed to extract any files to my harddisk, so I must open the ZIP-File and read the needed files step by step into a MemoryStream.</p>\r\n<p>What is the best way to do this?</p>\r\n<p>Can I read the first XML-File into a MemoryStream and then open the file with XDocument.load(MemoryStream...)?<br>When the Archive is encrypted, how can I find out the entryption-mode (e.g. AES256 or other method)?<br>Can I change different entries in the XML-File/MemoryStream and save back the changes into ZIP-File without saving about the harddisk (I don't know the count of files)?</p>\r\n<p>I'm very happy when you can answer the above questions.</p>\r\n<p>Thanks a lot for your support.</p>\r\n<p>Regards,<br>Maximilian</p>",
