2. AssemblyInfo.cs中

　　　　

[assembly: AssemblyVersion("1.0.0.0")]

[assembly: AssemblyFileVersion("1.0.0.0")]
[assembly: log4net.Config.DOMConfigurator(ConfigFileExtension = "config", Watch = true)]

　　3.App.config

<configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
  </configSections>
  <log4net>
    <!--错误日志配置-->
    <appender name="ErrorAppender" type="log4net.Appender.RollingFileAppender">

      <param name="MaxFileSize" value="10240"/>
      <param name="StaticLogFileName" value="false"/>
      <param name="DatePattern" value="yyyyMMdd"/>
      <param name="RollingStyle" value="Date"/>
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%n异常时间：%d [%t] %n异常级别：%-5p %n异 常 类：%c [%x] %n%m %n "/>
      </layout>
    </appender>

    <!--信息日志配置-->
    <appender name="InfoAppender" type="log4net.Appender.RollingFileAppender">
