The above error was caused by the fact that i was running the above on a network without giving Ionic FullTrust via Caspol. I ran the caspol [you can also do that from admin tools] and then tried again and it works like a charm!!!</p>\r\n<p>&nbsp;</p>\r\n<p>&nbsp;</p>\r\n<p>Thanks again as the extraction is a charm with the dll.</p>",
