Paul H. Harder II commented on LOG4NET-287: ------------------------------------------- My, but that does sound complex. While the idea of disallowing optimization may prove useful as a diagnostic, it won't work for production and I'm looking for a fix now. Until a version of log4net comes out that fixes this issue, I will just duplicate some of what it does, by writing my own BuildLogString method: myLogger.Info(Util.BuildLogString("Something happened here")); That method uses StackFrame (GetFileLineNumber and GetFileName), PathGetFileNameWithoutExtension, Assembly.GetCallingAssembly().FullName, and a regex to build a string that contains what log4net should be putting out when it logs two levels of class, the line number, and a message. my log4net config file section then uses conversion patterns like this: <conversionPattern value="%utcdate{ISO8601} %-12thread %-5level %message%newline%exception"/> This is not ideal, but it works, both in my console app test program and in the Windows service. > Wrong line number for log > -------------------------- > > Key: LOG4NET-287 > URL: https://issues.apache.org/jira/browse/LOG4NET-287 > Project: Log4net > Issue Type: Bug > Components: Appenders > Affects Versions: 1.2.10 > Environment: Windows XP, .NET 3.5, Microsot Virsual Studio > Reporter: Shuang yin Liu > > In our project, we use the line number function of log4net. Many of log line > numbers are 1 line after the actual line.
