In log4net, we can use the FileAppender to log information into text files. There are two ways to specify the file: 1. Specify the file name in absolutely path. For example: <log4net> <appender name = "FileAppender" type = "log4net.Appender.FileAppender" > <file value = "c:\logs\log-file.txt" /> <appendToFile value = "true" /> <lockingModel type = "log4net.Appender.FileAppender+MinimalLock" /> <layout type = "log4net.Layout.PatternLayout" > <conversionPattern value = "%date [%thread] %-5level %logger - %message%newline" /> </layout> </appender> </log4net> Obviously, the file will be created in c:\logs\log-file.txt 2. Specify the file name in relative path. For example: <log4net> <appender name = "FileAppender" type = "log4net.Appender.FileAppender" &g
