Log4net - Suppress “exception” from being appended to custom “PatternLayout”

Question

When using a custom \"PatternLayout\", log4net is appending the \"exception\" information (when present) to every log entry. I am trying to control the output of the message

Answer 1

Configure the layout like this:

<layout type="Example.Class.CustomLog4netLayouts,Example">
    <IgnoresException value="False" />
    ...

Setting IgnoresException to false tells the appender that the layout will take care of the exception. Thus you can choose not to print the stack trace.
