Append current Date to Log file with Log4NetTake the tour × Stack Overflow is a question and answer site for professional and enthusiast programmers. It's 100% free, no registration required. All I want to do is append the current date and time to my log file, say: "export_(Wed_Feb_21_2009_at_1_36_41PM)" Here is my current config from my app.config Is appending the date to my log file possible, or is it one of those things I need to do in code and not config?
