我正在编写一个简单的测试项目来试验log4net,而且我已经立即打了一个墙.无论我在配置文件中执行什么操作,都会初始化我的记录器,并将所有"IsXXXXEnabled"标志设置为false.这是我非常简单的app.config:

  <log4netgroup>
    <log4net xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
        <param name="LogName" value="Application" />
        <param name="ApplicationName" value="HelloProgram" />
        <threshold value="DEBUG"/>
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%logger - %newline%message" />
        </layout>
      </appender>

      <root>
        <level value="DEBUG" />
        <appender-ref ref="EventLogAppender" />
      </root>
      <logger name="HelloLogger">
        <level value="DEBUG" />
        <appender-ref ref="EventLogAppender" />
      </logger>
    </log4net>
  </log4netgroup>

以下是Main中的简单测试:

    ILog Log = LogManager.GetLogger("HelloLogger");

    if(Log.IsErrorEnabled)
        Console.WriteLine("The logger is working!");
    else
        Console.WriteLine("Nope");

输出是"不".我尝试将阈值和级别值切换为"ALL",但没有任何改变.这看起来很简单,我错过了什么来启用一切？谢谢

我已经编写了3个ASP.net MVC Web应用程序,并且所有这些应用程序都部署在我的ISP的共享主机服务器上.

所有3个应用程序在配置和设置方面都非常相似.第一个应用程序部署到与第二个和第三个不同的服务器.第一个应用程序没有给我任何错误.

第二个和第三个应用程序稍微吐出以下SecurityException :随机:

例外文字:

 Security Exception

我一直试图在我的asp.net Web应用程序中记录log4net,但没有成功或任何明显的错误.我试图使用ADONetAppender appender与以下配置:

<log4net>
<appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
  <bufferSize value="1" />
  <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
  <connectionString value="server=" />
  <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception],[Context]) VALUES 
                            (@log_date, @thread, @log_level, @logger, @message, @exception, @context)" />
  <parameter>
    <parameterName value="@log_date" />
    <dbType value="DateTime" />
    <layout type="log4net.Layout.RawTimeStampLayout" />
  </parameter>
  <parameter>
    <parameterName value="@thread" />
    <dbType value="String" />
    <size value="32" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%t" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@log_level" />
    <dbType value="String" />
    <size value="512" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%p" />
    </layout>
  </parameter>
  <parameter> …

我想将log4net记录的所有内容重定向到System.Diagnostics Trace类.我对我应该做的事情的理解是将log4net指向system.diagnostics.traceappender,然后配置system.diagnostics.这是我的web.config中的重要部分:

<log4net>
<appender name="trace" type="log4net.Appender.TraceAppender, log4net">
  <immediateFlush value="true" />
  <layout type="log4net.Layout.PatternLayout,log4net">
    <param name="ConversionPattern"
         value="%d{ABSOLUTE} %-5p %c{1}:%L - %m%n" />
  </layout>
</appender>

<root>
  <priority value="DEBUG"/>
  <appender-ref ref="trace"/>
</root>    
</log4net>


<system.diagnostics>
<sources>

  <source name="Console" switchName="DefaultSwitch">
    <listeners>
      <add type="System.Diagnostics.DefaultTraceListener" name="Default">
        <filter type="" />
      </add>
    </listeners>
  </source>

  <source name="Metabase" switchName="MetabaseSwitch">
    <listeners>
      <add name="MetabaseListener" />
      <remove name="Default" />
    </listeners>
  </source>

  <source name="TextFile" switchName="TextFileSwitch">
    <listeners>
      <add name="TextFileListener" />
      <remove name="Default" />
    </listeners>
  </source>

</sources>
<sharedListeners>
  <!--<add name="ConsoleListener" type="XXX.Manufacturing.Utilities.Diagnostics.ColorConsoleTraceListener,XXX.Manufacturing.Utilities" />-->
  <add name ="TextFileListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="TextFile.log" /> …

我有一个使用log4net的.Net 4.0 Windows服务应用程序.

这是我的log4net配置.

<log4net>

    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger [%property{Context}] - %message%newline" />
    </layout>
  </appender>

  <appender name="ColorConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
    <mapping>
      <level value="ERROR" />
      <foreColor value="Red, HighIntensity" />
    </mapping>
    <mapping>

      <foreColor value="Red, HighIntensity" />
