无法识别的配置节log4net的(Unrecognized configuration section log4net) – herizai – 博客园

来源: 无法识别的配置节log4net的(Unrecognized configuration section log4net) – herizai – 博客园

每个配置文件中只允许存在一个 <configSections> 元素,并且,如果存在该元素,它还必须是根 <configuration> 元素的第一个子元素。

 

问题:

I have this code in web.config:

复制代码
<log4net>
  <root>
    <level value="ALL" />
    <appender-ref ref="LogFileAppender" />
  </root>
  <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
    <param name="File" value="D:\logFileFaculty.txt" />
    <param name="AppendToFile" value="true" />
    <rollingStyle value="Size" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="10MB" />
    <staticLogFileName value="true" />
    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
    </layout>
  </appender>
</log4net>
复制代码

And I have downloaded log4net.dll and placed it in Bin Folder.

In one of My aspx.cs pages I have added this code:

using log4net;
[assembly: log4net.Config.XmlConfigurator(Watch = true)]


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

But it’s giving error as Unrecognized configuration section log4net.

 

解决方案:

You need to declare the log4net section:

<configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>

Take a closer look at the documentation which explains the necessary things to do.
