How to create a file in AppData folder using log4net

Question

How to create a log file in appData folder. Path: C: \ Users \ MYNAME \ AppData \ Roaming \ Project \ My Project \ Application. As soon as my project starts, the project folder is created on this path, where this path is hard-coded. How to add a log file to this folder using log4net? I made changes to the configuration file

<?xml version="1.0"?> <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <appender name="Console" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <!-- Pattern to output the caller file name and line number --> <conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" /> </layout> </appender> <appender name="RollingFile" type="log4net.Appender.RollingFileAppender"> <file value="${APPDATA}\\Roaming\\Project\\My Project\\Application\\Log.txt"/> <appendToFile value="true" /> <maximumFileSize value="100KB" /> <maxSizeRollBackups value="10" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%level %thread %logger - %message%newline" /> </layout> </appender> <root> <level value="ALL" /> <appender-ref ref="Console" /> <appender-ref ref="RollingFile" /> </root> </log4net> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> </startup> <system.serviceModel> <bindings /> <client /> </system.serviceModel> </configuration> 

This does not create any files in this folder. And all permissions are granted by the Administrator.

It seems that you are doing it right, however there are cases where it seems that the shell of the variable matters: Another question on this

You can try if: ${AppData} works
