    "Html": "<p>The error you're getting has nothing to do with an error in SharpZipLib.&nbsp;</p>\r\n<p>They are different implementations.&nbsp; Any similarities are coincidental.</p>\r\n<p>The stack trace indicates that you are trying to update a zipfile.&nbsp; At least one of the entries in the existing zip file is unchanged. DotNetZip will copy through the metadata+data for each unchanged zip entry, from the source to the target zip file.</p>\r\n<p>To do this, DotNetZip needs to seek within the original (source) Zip file, to the location of the original entry.&nbsp; It then does a read/write copy loop.&nbsp; But the Seek is failing because the original, source zip file is closed.</p>\r\n<p>I don't kniow why that would be the case.&nbsp; I'd like to see more of your code - for example, how do you instantiate the ZipFile object, before passing it to the method you included above?</p>\r\n<p>&nbsp;</p>",
