k, this is embarassing now... I've tried every combination I could think of
and I'm still getting the same result. Neither the datetime output nor the
%newline are working for me. What the hell am I doing wrong??? I feel like
such a poser! ("hey, maybe I'll just get the log4net guys to write the
WHOLE application for me!") Here is my config file and below that is the
output I get:
<log4net>
<appender name="SystemEventInfoLog"
type="log4net.Appender.RollingFileAppender">
<param name="File" value="../logging/" />
<param name="AppendToFile" value="true" />

<header value="[BEGIN LOGGING AT %date ]%n"
type="log4net.Util.PatternString" />
<footer value="[END LOGGING AT %d ]%newline"
type="log4net.Util.PatternString" />
<param name="ConversionPattern" value="%d [%t]
%-5p %c [%x] - %m%n" />
</layout>
</appender>
<!-- Set root logger level to DEBUG and its only appender to A1
-->
<root>
<appender-ref ref="SystemLog" />
<appender-ref ref="SystemEventInfoLog"/>
</root>
</log4net>
Output from the SystemEventInfoLog appender:
[BEGIN LOGGING AT %date ] %n [END LOGGING AT %d ]
[BEGIN LOGGING AT %date ] %n [END LOGGING AT %d ]
[BEGIN LOGGING AT %date ] %n [END LOGGING AT %d ]
/*******************************************************
Output from System Log appender:
[BEGIN LOGGING AT %date ]%n[END LOGGING AT %d ]%newline[BEGIN LOGGING AT
%date ]%n[END LOGGING AT %d ]%newline
/*******************************************************
I'm going to be shot if my manager finds out I spent an hour testing
header/footer dates this morning. These dates are rather important, though,
because they tell me when the application was started and when the first
errors started to occur. This app may be left running independantly for
weeks on end and eventually the logic will be moved into a window service.

Thank you for your patience.

I found these sentances helpful:
"
The goal of this class is to Format a LoggingEvent as a string. The
results depend on the conversion pattern.

Unlike the PatternLayout however the PatternString does does not render
properties of a specific LoggingEvent but of the process in general.

I used a PatternString in the header and footer nodes because I didn't
have a LoggingEvent to pull information out of. PatternString and
PatternLayout have some overlap with things like %date/%d and
%newline/%n. That's where I got confused. I thought I could use %n and
%d as shortcuts in a PatternString but you can't, you need to use the
full %date and %newline patterns.
Line 168 of log4net.Util.PatternStringConverters.DatePatternConverter
confirms that the %date pattern of PatternString uses the current
date/time:
m_dateFormatter.FormatDate(DateTime.Now, writer);
Had that been a PatternLayout, it would have used
loggingEvent.TimeStamp for its DateTime value.
Hope that helps,
Ron
