How do I display full exception information including inner exception(s)

[David Thielen]

Our log4net (config below) gives us the Exception.Message, but that's all. I 
need it to log the stack trace and all inner exceptions, with the stack trace 
for each of those.
How do I do this?
<log4net>
    <appender name="RollingFileAppender" 
type="log4net.Appender.RollingFileAppender">
        <param name="File" value="C:/temp/AutoTag_Word.log"/>
        <param name="AppendToFile" value="true"/>
        <param name="MaxSizeRollBackups" value="10"/>
        <param name="MaximumFileSize" value="1000KB"/>
        <param name="RollingStyle" value="Size"/>
        <param name="StaticLogFileName" value="true"/>
        <layout type="log4net.Layout.PatternLayout">
            <param name="ConversionPattern" value="%d [%t] ac.server %-5p %c - 
%m%n%exception"/>
        </layout>
    </appender>
    <root>
        <level value="DEBUG"/>
        <appender-ref ref="RollingFileAppender"/>
    </root>
    <logger name="WindwardArrow.net.windward.arrow.datasource.ado">
        <level value="DEBUG"/>
    </logger>
</log4net>
