How to check log4net log path?

Question

My configuration file is :

<log4net  xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <appender name="InfoFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="D:/" />
            <appendToFile value="true" />
            <param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
            <rollingStyle value="Date" />
            <maxSizeRollBackups value="100" />
            <datePattern value="YYYY-MM-DD'.log'"/>
            <maximumFileSize value="1024KB" />
            <staticLogFileName value="false" />
            <encoding value="utf-8"/>           
            <filter type="log4net.Filter.LevelRangeFilter">
                <param name="LevelMin" value="INFO" />
                <param name="LevelMax" value="INFO" />
            </filter>
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date %-5level %logger  - %message%newline" />
            </layout>
        </appender>
        <appender name="ErrorFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="D:/" />
            <appendToFile value="true" />
            <rollingStyle value="Size" />
            <maxSizeRollBackups value="100" />
            <maximumFileSize value="10240KB" />
            <datePattern value="YYYY-MM-DD'.log'"/>
            <staticLogFileName value="true" />
            <encoding value="utf-8"/>
            <filter type="log4net.Filter.LevelRangeFilter">
                <param name="LevelMin" value="WARN" />
                <param name="LevelMax" value="FATAL" />
            </filter>
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date %-5level %logger - %message%newline" />
            </layout>
        </appender>
        <root>
            <level value="INFO" />
            <appender-ref ref="InfoFileAppender" />
            <appender-ref ref="ErrorFileAppender" />
        </root>
    </log4net>

in app.config.

But it has no log file in disk D:!!!!

Answer 1

Just verified your config - works fine. You probably didn't initialize log4net properly. You should add into AssemblyInfo.cs file:

[assembly: XmlConfigurator(Watch = true)]

Or you can use XmlConfigurator.ConfigureAndWatch method or simply

XmlConfigurator.Configure();

Unlike NLog, log4net cannot initialize itself.

NOTES: You should change your date pattern to yyyy-MM-dd'.log' - year and day should be lowercase letters. Also you can write several levels with single appender. There is no need to create two appenders which write to same file.

Answer 2

Try as below

<file value="D:/ABC.txt" />

assemblyinfo.cs

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "~\\Abc\\xyz\\log4net.config", Watch = true)]
