log4net保存到数据库系列二：独立配置文件中配置log4net

园子里面有很多关于log4net保存到数据库的帖子,但是要动手操作还是比较不易，从头开始学习log4net数据库日志一、WebConfig中配置log4net

• 一、WebConfig中配置log4net
• 二、独立配置文件中配置log4net
• 三、代码中xml配置log4net
• 四、完整代码配置log4net
• 五、新增数据库字段

下面先一点一点来学习如果进行配置

1.下载，2.数据库脚本，请参考log4net保存到数据库系列一：WebConfig中配置log4net

3.配置文件

log4net.config文件属性为嵌入的资源，始终复制

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>
<log4net>
    <!--注册Appender-->
    <root>
      <level value="ALL" />
      <appender-ref ref="AdoNetAppender" />
    </root>
    <!--配置Appender-->
    <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">

        <layout type="log4net.Layout.RawTimeStampLayout" />
      </parameter>
      <parameter>

        <dbType value="String" />
        <size value="255" />
        <layout type="log4net.Layout.PatternLayout">

      </parameter>
      <parameter>
        <parameterName value="@log_level" />
        <dbType value="String" />
        <size value="50" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%level" />

        </layout>
      </parameter>
      <parameter>
        <parameterName value="@message" />
        <dbType value="String" />
        <size value="4000" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%message" />
        </layout>
      </parameter>
      <parameter>
        <parameterName value="@exception" />
        <dbType value="String" />
        <size value="2000" />
        <layout type="log4net.Layout.ExceptionLayout" />
      </parameter>
    </appender>
  </log4net>
</configuration>

log4net.config配置文件

4.设置监控

AssemblyInfo.cs中增加代码

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

5.测试代码

6.测试成功
