Log4net 配置输出文本, 按年月日分文件夹 z

在项目中新建 “log4net.config” 文件

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

    <configSections>

        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

    </configSections>

    <log4net>

        <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">

            <File value="Log\" />

            <!--是否是向文件中追加日志-->

            <AppendToFile value="true" />

            <!--每个文件的大小-->

            <MaximumFileSize value="1MB"/>

            <!--log文件数-->

            <MaxSizeRollBackups value="" />

            <!--日志文件名是否是固定不变的-->

            <StaticLogFileName value="false" />

            <!--日志文件名格式为:yyyy-MM-dd.log-->

            <DatePattern value="yyyy\\MM\\dd\\yyyy-MM-dd'.log'" />

            <!--日志根据日期滚动-->

            <RollingStyle value="Date" />

            <layout type="log4net.Layout.PatternLayout">

                <ConversionPattern value="%date %logger [%thread] %level %message%newline" />

            </layout>

        </appender>

        <root>

            <!--(高) OFF > FATAL > ERROR > WARN > INFO > DEBUG > ALL (低) -->

            <level value="all" />

            <appender-ref ref="RollingLogFileAppender" />

        </root>

    </log4net>

</configuration>

配置好后在程序集 AssemblyInfo.cs 中加入

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

或者用代码初始化

private void InitLog4net()

{

    var logCfg = new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.config");

    XmlConfigurator.ConfigureAndWatch(logCfg);

    //修改日志路径

    var repository = LogManager.GetRepository();

    var appenders = repository.GetAppenders();

    var targetApder = appenders.First() as RollingFileAppender;

    targetApder.File = string.IsNullOrWhiteSpace(Settings.Default.LogPath) ? Path.Combine( Environment.CurrentDirectory,"log.txt") : Settings.Default.LogPath;

    targetApder.ActivateOptions();

    this.log = LogManager.GetLogger("mainlog");

}
