How to tell NLog to log exceptions?

问题

Target:

<targets>
    <target name="file" xsi:type="File" layout="${longdate} ${level} ${message} ${exception}" fileName="${basedir}/log.txt" archiveAboveSize="10485760" />
</targets>

When I call Logger.Error("some message", e), where e is some exception object, it only logs the message, not the exception information. I need it to output exception message and stack trace. Any ideas what I am doing wrong?

回答1:

Try to use ${exception:innerFormat=Message,StackTrace}. Here is the documentation.

回答2:

I've found ${exception:format=tostring} to be the best format for logging full details.

Yep try adding

includeSourceInfo="true"

to your target file, like;

 <target name="viewer"
            xsi:type="NLogViewer"
            includeSourceInfo="true"
            address="udp://127.0.0.1:9999" />
