lognet 配置

1：引入log4net

2：新建配置文件 logn4net.config

具体如下所示：

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <!--Log4net Begin by Tony  2008.11.20-->
  <log4net>
    <appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
      <bufferSize value="10" />

      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data,Version=10.0.1600.22, Culture=neutral" />
      <connectionString value="data source=.;initial catalog=Test;integrated security=false;persist security info=True;User ID=sa;Password=301415" />
      <commandText value="INSERT INTO ErrorLog ([dtDate],[sThread],[sLevel],[sLogger],[sMessage],[sException]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />

  <!--参数集合，和数据库字段对应-->
      <parameter>
        <parameterName value="@log_date" />
        <dbType value="DateTime" />
        <layout type="log4net.Layout.RawTimeStampLayout" />
      </parameter>
      <parameter>
        <parameterName value="@thread" />
        <dbType value="String" />
        <size value="100" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%t" />
        </layout>
      </parameter>
      <parameter>
        <parameterName value="@log_level" />
        <dbType value="String" />
        <size value="200" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%p" />
        </layout>
      </parameter>
      <parameter>
        <parameterName value="@logger" />
        <dbType value="String" />
        <size value="500" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%logger" />
        </layout>
      </parameter>
      <parameter>
        <parameterName value="@message" />
        <dbType value="String" />
        <size value="3000" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%m" />
        </layout>
      </parameter>
      <parameter>
        <parameterName value="@exception" />
        <dbType value="String" />
        <size value="4000" />
        <layout type="log4net.Layout.ExceptionLayout" />
      </parameter>
    </appender>
    <!-- setup the root category, add the appenders and set the default level -->
    <root>
      <level value="WARN"/>
      <level value="INFO"/>
      <level value="DEBUG"/>
      <level value="FINE"/>
      <appender-ref ref="ADONetAppender" />
    </root>
    <!-- specify the level for some specific categories -->
    <logger name="iNotes">
      <level value="WARN"/>
      <level value="INFO"/>
      <level value="DEBUG"/>
      <level value="FINE"/>
      <appender-ref ref="ADONetAppender"/>
    </logger>
    <logger name="StellaLogger">
      <level value="ALL"/>
      <appender-ref ref="AdoNetAppender" />
    </logger>
  </log4net>
  <!--Log4net End-->
</configuration>

3：添加集合 在Properites.AssemblyInfo.cs 文件里面

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "logn4net.config", ConfigFileExtension = "config", Watch = true)]

4：实例化对象

 private static log4net.ILog myLogger = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);  

5：输出

            myLogger.Error("asd");
            myLogger.Debug("asd");
            myLogger.Info("asd"); 
            myLogger.Fatal("asd");
