每当应用程序开始使用lo4net时如何创建新的日志文件 [英] how to create a new log file every time when the application starts using lo4net

问题描述

每次应用程序开始使用lo4net时如何创建新的日志文件.或者我想每次清除日志文件. RollingFileAdapter没有给我任何解决方案. 看到我的代码:

how to create a new log file every time when the application starts using lo4net. or I wanted to clear the log file each time. RollingFileAdapter doesn't give me any solution. see my code:

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <param name="File" value="Log.txt"/>
  <param name="AppendToFile" value="true" />
  <rollingStyle value="Size" />
  <maxSizeRollBackups value="10" />
  <maximumFileSize value="1MB" />
  <staticLogFileName value="true" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%identity - [%date] [%level] %class %method  %message %exception %newline" />
  </layout>
</appender>

在这里我必须添加任何其他内容吗?

here I have to add anything or anything else?

现在我更改为此名称，但是我希望为每次执行添加一个带有日期时间的文件名.

Now I changed to this but I want a filename added with datetime for each execution.

<appender name="RollingFileAppender"type="log4net.Appender.RollingFileAppender"> 
  <file value="log\" />
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
  <datePattern value="dd.MM.yyyy'.log'" />
  <appendToFile value="false" />
  <staticLogFileName value="false" />
  <rollingStyle value="Composite" />
  <maxSizeRollBackups value="10" />
  <maximumFileSize value="5MB" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="[%date] [%level] Class Name: %class Method Name: %method line No: %line %message %exception %newline" />
  </layout>

推荐答案

您可以在每次执行时创建一个新的日志文件:rollingStyle->一次，并将appendtofile设置为false:

You can make a new log file on each execution: rollingStyle -> once, and set appendtofile to false:

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <param name="File" value="Log.txt"/>
  <param name="AppendToFile" value="false" />
  <rollingStyle value="Size" />
  <maxSizeRollBackups value="10" />
  <maximumFileSize value="1MB" />
  <staticLogFileName value="true" />
   <rollingStyle value="Once" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%identity - [%date] [%level] %class %method  %message %exception %newline" />
  </layout>
</appender>
