LocationInformation in LoggingEvent in CustomAppendar

问题

I have written custon Appendar and override Append method. I am getting LoggingEvent in that method but when I looked at LocationInformation it is empty it shows only "?" in following properties.

protected override void Append(log4net.Core.LoggingEvent loggingEvent)
{

ClassName = loggingEvent.LocationInformation.ClassName /*contains "?"*/,
MethodName = loggingEvent.LocationInformation.MethodName /*contains "?"*/,
FileName = loggingEvent.LocationInformation.FileName /*contains "?"*/,
FullInfo = loggingEvent.LocationInformation.FullInfo /*contains "?"*/,

}

What I am doing wrong ?

Thanks

回答1:

Could you try adding following line in the constructor of your custome appender:

Fix = FixFlags.All;

回答2:

Set the Fix Property on the LoggingEvent in the Append-Method:

protected override void Append(LoggingEvent loggingEvent)
{
     loggingEvent.Fix = FixFlags.All;

     var className = loggingEvent.LocationInformation.ClassName;
     // ... 
}
