在C＃中没有创建log4net日志文件

Question

log file is not getting created, using below call to get logger and config file. is it required to give full path for file?

private static readonly log4net.ILog logger = log4net.LogManager.GetLogger
(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821" requirePermission="false"/>
    </configSections>

    <!-- Log4net Logging Setup -->
    <log4net>
        <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="log.txt" />
            <appendToFile value="true" />
            <rollingStyle value="Size" />
            <maxSizeRollBackups value="50" />
            <maximumFileSize value="50MB" />
            <staticLogFileName value="true" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
            </layout>
        </appender>
        <root>
            <level value="ALL" />
            <appender-ref ref="RollingFileAppender" />
        </root>
    </log4net>
</configuration>

Answer 1

Does your code call

log4net.Config.XmlConfigurator.Configure();

on startup?

The <root> section I use has priority , not level :

    <root>
        <priority value="ALL" />
        <appender-ref ref="LogFileAppender" />
    </root>

(Apparently, that's not the issue https://stackoverflow.com/a/24188507/21336 )

Answer 2

after adding below line in AssemblyInfo.cs, could see log file getting created and logs coming. [assembly: log4net.Config.XmlConfigurator(Watch = true)]
