log4net菜鸟指南二----生成access和txt

前言

有可能目标计算机缺少某些组件，导致无法生成access文件，或者打不开文件，这时txt文件就可以方便的使用了

 

一，标准的控制台程序输出日志到access

<?xml version="1.0" encoding="utf-8" ?>
<log4net xmlns="urn:log4net">
  <root xmlns="">
    <level value="ALL" />
    <appender-ref ref="AdoNetAppender_Access" />
  </root>
  <appender  xmlns="" name="AdoNetAppender_Access" type="log4net.Appender.AdoNetAppender">
    <connectionString value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=log\log.mdb" />
    <commandText value="INSERT INTO Table1([LogDate],[Thread],[logLevel],[Logger],[Message]) VALUES(@logDate, @thread, @logLevel,@logger,@message)" />

    <!--BufferSize为缓冲区大小，只有日志记录超10条才会一块写入到数据库-->
    <bufferSize value="10"/>
    <!--定义各个参数-->
    <parameter>
      <parameterName value="@logDate" />
      <dbType value="String" />
      <size value="240" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@thread"/>
      <dbType value="String" />
      <size value="240" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%thread" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@logLevel" />
      <dbType value="String" />
      <size value="240" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%level" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@logger" />
      <dbType value="String" />
      <size value="240" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%logger" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@message" />
      <dbType value="String" />
      <size value="240" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%message" />
      </layout>
    </parameter>
  </appender>
</log4net>
