Log4Net, how to add a custom field to my logging

Question

I use the log4net.Appender.AdoNetAppender appender.
My log4net table are the following fields [Date],[Thread],[Level],[Logger],[Message],[Exception]

Answer 1

1) Modify the command text: INSERT INTO Log4Net ([Date],[Thread],[Level],[Logger],[Message],[Exception],[MyColumn]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception, @CustomColumn)

2) Add the parameter definition for the custom column:

3) Then use one of log4net’s contexts to transfer values to the parameter:

// thread properties...
log4net.LogicalThreadContext.Properties["CustomColumn"] = "Custom value";
log.Info("Message"); 

// ...or global properties
log4net.GlobalContext.Properties["CustomColumn"] = "Custom value";
