如何使log4net在前一个文件大于文件限制时创建一个新文件？

Question

当前一个文件变得太大时,如何让log4net创建一个新文件？

我有一个任务,需要1个小时才能完成并生成大约40MB的日志,但是我想要40个1MB的文件而不是一个40MB的文件.我没有配置log4net.我现在拥有的只是库和代码:

private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

然后我就这样做:

log.Debug("some message");

怎么做？

编辑:

<?xml version="1.0"?>
<configuration>
    <startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
    </startup>
    <appSettings>
      <add key="mymail" value="mitja.resek@gmail.com" />
    </appSettings>
    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="log.txt" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="1MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>
</configuration>

这是我的app.config但我仍然有40MB文件:S

Answer 1

<appender name="RollingFileAppenderV1" type="log4net.Appender.RollingFileAppender">
    <file type="log4net.Util.PatternString" value="F:\HornetFeed\%property{LogName}" />
    <appendToFile value="true" />
    <rollingStyle value="Size" />
    <maxSizeRollBackups value="-1" />
    <maximumFileSize value="5000KB" />
    <staticLogFileName value="true" />
    <countDirection value="1"/>
    <layout type="log4net.Layout.PatternLayout">
       <conversionPattern value="%m%n" />
   </layout>
   <filter type="log4net.Filter.PropertyFilter">
       <Key value="Version" />
       <StringToMatch value="1" />
   </filter>
   <filter type="log4net.Filter.DenyAllFilter" />
</appender>

这将创建无限的文件备份,countdirection> 0,以便最新的文件具有最新/最大的名称,即最新备份的log.5(第5次备份).

<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="logfile" />
    <appendToFile value="true" />
    <rollingStyle value="Composite" />
    <datePattern value=".yyyyMMdd-HHmm" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="1MB" />
    <countDirection value="1"/>
    <layout type="log4net.Layout.PatternLayout">
       <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
   </layout>
</appender>

这是一个Composite RollingFileAppender,每分钟最多可保留10个1MB日志备份.

App.config中

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    </configSections>
    <log4net debug="false">
        <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="logfile" />
            <appendToFile value="true" />
            <rollingStyle value="Composite" />
            <datePattern value=".yyyyMMdd-HHmm" />
            <maxSizeRollBackups value="10" />
            <maximumFileSize value="1MB" />
            <countDirection value="1"/>
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
            </layout>
        </appender>
        <root>
            <priority value="ALL" />
            <appender-ref ref="RollingLogFileAppender" />
        </root>
        <category name="testApp.LoggingExample"><priority value="ALL" /></category>
    </log4net>
</configuration>
