Windows Explorer is smart enough to know to look into any file with a .DLL extension, and display that version number on the properties tab.&nbsp; It is not something that is simply accessible,\r\n though, in the set of ZipEntry metadata.</p>\r\n<p>To get the file version of the DLL, you'd need to have some code that inspects the DLL itself, and learns the embedded version number.&nbsp; You can do this using the .NET Framework class\r\n<a href=\"http://msdn.microsoft.com/en-us/library/system.diagnostics.fileversioninfo.aspx\">\r\nSystem.Diagnostics.FileVersionInfo</a> on a filesystem file.&nbsp; <a href=\"http://stackoverflow.com/questions/349943/read-a-non-net-dll-version-from-c\">\r\nSee here</a>.</p>\r\n<p>So I think to do what you want, you'd have to extract the DLL to a temporary file, then create a FileVersionInfo object for that temporary file, and examine the FileVersion property on that object.</p>\r\n",
