The first time this runs (and the file is already in the zip, thus is being removed and re-added already on the first attempt), this works well.</p><p>&nbsp;</p><p>The second&#43;&#43; time this code in executed it runs without exeception, but the file in the zip is of 0 bytes length, though the memory stream contained something like 10000 bytes of data.</p><p>&nbsp;</p><p>But this data somehow gets lost. The workaround is to do a ZipFile.Save() after removing the entry and again after adding it.</p><p>&nbsp;</p><p>I use Ionic.Zip.Reduced Version 1.9.1.8 (the latest).</p><p>&nbsp;</p><p>If this a bug in the library?</p><p>&nbsp;</p><p>Thanks</p><p>Karlo</p></pre>\r\n</div>\r\n&nbsp;</pre>\r\n</div>\r\n",
