Unfortunately I have the same problem and found no solution for this issue (using Ionic.Zip.dll 1.9.1.8).\r<br />\n<br />\nAfter uploading a ZIP file I must validate and manipulate the file in memory. Therefore I must execute the Save method to get the file into MemoryStream (to be able to use OpenReader()). To update the MemoryStream after changing the content I have to execute the Save method of the manipulated ZipFile object again but get the known exception.\r<br />\n<br />\nI try to prevent using object copies in memory because of large uploaded files. A previous version already goes that way resulting in OutOfMemory exceptions.\r<br />\n<br />\nThank you for any hint.\r<br />\n<br />\nBest Regards\r<br />\nMarcus<br />\n",
