    "Html": "<p>yes, that would work. From the documentation on PutNextEntry() :</p>\r\n<blockquote>\r\n<p>This method returns the <span class=\"code\">ZipEntry</span>. You can modify public properties on the <span class=\"code\">ZipEntry</span>, such as <a href=\"http://cheeso.members.winisp.net/DotNetZipHelp/html/f7bc4e03-e417-79e0-b024-9abc8dfd7033.htm\">Encryption</a>, <a href=\"http://cheeso.members.winisp.net/DotNetZipHelp/html/c21d4132-4533-9740-f3e0-2893e85fad67.htm\">Password</a>, and so on, until the first call to <span class=\"code\">ZipOutputStream.Write()</span>, or until the next call to <span class=\"code\">PutNextEntry()</span>. If you modify the <span class=\"code\">ZipEntry </span><em>after</em> having called <span class=\"code\">Write()</span>, you may get a runtime exception, or you may silently get an invalid zip archive.</p>\r\n</blockquote>\r\n<p>I cannot remember what specific situation I was referring to with \"you may silently get an invalid zip archive\".&nbsp; That seems like pretty impolite behavior by the library. I'll have to look into that rough edge.&nbsp; Anyway, don't do that and you'll avoid that problem.</p>\r\n<p>Here's the way to think about it: the entry metadata (like entry name, timestamp, encryption type, password, and so on) gets emitted into the zipfile stream before any of the compressed data.&nbsp; So, as soon as you call&nbsp;Write() the first time, the metadata gets written, and updating the metadata after that, won't do what you think it should do.&nbsp;</p>\r\n<p>Regarding your code: not sure why you'd assign zipOutStream variable the the result of the method WriteFileToZipOutStream().&nbsp; Seems inappropriate, just from my understanding of what you are doing.</p>",
