Log4Net can't find %username property when I name the file in my appender

Question

log4net doesn\'t do the correct PatternString substitution for my login name. I want my log to be

Logs\\YYYYMMDD\\MSMQcore_[username].lo

Answer 1

Just one improvement to the Kit's solution: Use attribute

[TypeConverter("namespace.ConfigurationSettingsPatternStringConverter")]
public class ConfigurationSettingsPatternString : PatternString
{

And the call to

ConverterRegistry.AddConverter(
// type we want to convert to (from string)...
typeof(ConfigurationSettingsPatternString),
// the type of the type converter that will do the conversion...
typeof(ConfigurationSettingsPatternStringConverter));

is no longer required.
