Hello, you can try this: download log4net sources and attach them to your project instead of reference to log4net.dll. Now you'll be able to debug inside of AdonetAppender and you can find what exactly is null and guess the correct value, I hope. Radovan Raszka

I definitely get the same error as you. Can I ask if you are using MySql at all? Unfortunately though, I havent had any luck with asking this question on this list, it would appear that the list is not as busy as I thought it initially was, or the other subscribers are unable to comment. To help you with your problem, if it isnt the same as mine, would be to post your code on the list itself. That gives everyone the chance to take a look and see if they can spot the issue. If you do have the same problem as me, could you post your solution should you fix it? That way others, including myself will be able to resolve this in future. ________________________________ Date: Wed, 20 May 2009 22:02:14 +0000 From: lewd_revel...@yahoo.co.uk Subject: Key cannot be null error To: log4net-user@logging.apache.org Hello, Could someone explain to me what the following error means please? log4net:ERROR [AdoNetAppender] Could not open database connection [] System.ArgumentNullException: Key cannot be null.
