我正在使用 Log4Net 在我的 Web 应用程序中记录异常。

在这里，我找到了一个配置示例：http ://www.cshaptocsharp.com/log4net-configuration-for-rockin-loggin

<?xml version="1.0"?>

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

  <log4net>
    <!--
  This writes the log information to the console window.  It only logs events
  that are at least at the INFO level (which would mean that DEBUG events are not
  captured.
  -->
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date{ABSOLUTE} [%thread] %level %logger - %message%newlineExtra Info: %property{testProperty}%newline%exception"/>
      </layout>
      <filter type="log4net.Filter.LevelRangeFilter">
        <levelMin value="INFO"/>
        <levelMax value="FATAL"/>
      </filter>
    </appender>
    <!--
  This stores information in the log.txt file.  It only captures log events
  that contain the key word test or error.
  -->
    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
           <file value="L:\Name\trunk\Name.Web\log.txt"/>
      <appendToFile value="true"/>
      <rollingStyle value="Size"/>
      <maxSizeRollBackups value="5"/>
      <maximumFileSize value="10MB"/>
      <staticLogFileName value="true"/>
      <filter type="log4net.Filter.StringMatchFilter">
        <stringToMatch value="test"/>
      </filter>
      <filter type="log4net.Filter.StringMatchFilter">
        <stringToMatch value="error"/>
      </filter>
      <filter type="log4net.Filter.DenyAllFilter"/>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %level %logger - %message%newline%exception"/>
      </layout>
    </appender>
    <root>
      <level value="FATAL"/>
      <appender-ref ref="RollingFileAppender"/>
    </root>
    <logger name="Log4NetTest.OtherClass">
      <level value="DEBUG"/>
      <appender-ref ref="ConsoleAppender"/>
    </logger>
  </log4net>


</configuration>

在我的课堂上，我有：

protected static readonly ILog log = LogManager.GetLogger(typeof(TemplateController));

在我的方法中，我有：

log4net.Config.XmlConfigurator.Configure();

                //————————–
                log.Error("sadi the great");
                log.Info("sadi the great");

但我有错误：

Rolling File appender 的工作配置如下：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    </configSections>
    <log4net>
         <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
             <file value="logger.log" />
             <appendToFile value="true" />
             <maximumFileSize value="100KB" />
             <maxSizeRollBackups value="2" />
             <layout type="log4net.Layout.PatternLayout">
             <conversionPattern value="%date %logger [%thread] [%ndc] (%file:%line) %level- %message%newline"/>
             </layout>
         </appender>

  <root>
      <level value="DEBUG" />      
  <appender-ref ref="RollingFile" />
  </root>
  </log4net>
</configuration>

并且您应该将目标框架更改为“.net framework 4”（在我的情况下默认情况下是不同的）检查这个会有用

在 AppConfig 文件中使用

<log4net debug="true">
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
  <layout type="log4net.Layout.XMLLayout" />
  <param name="File" value="BackgroundCheckLog/BackgroundCheckLog.log" />
  <param name="AppendToFile" value="true" />
  <param name="maximumFileSize" value="1000KB" />
  <param name="maxSizeRollBaenter code here`ckups" value="-1" />
  <layout type="log4net.Layout.PatternLayout">
    <header type="log4net.Util.PatternString" value="[START LOG] %newline" />
    <footer type="log4net.Util.PatternString" value="[END LOG] %newline" />
    <conversionPattern value="%d [%t] %-5p (%file:%line) - %m%n" />
  </layout>
</appender>
<root>
  <level value="ALL" />
  <appender-ref ref="RollingFile" />
</root>


protected static readonly ILog log = LogManager.GetLogger(typeof(TemplateController));

采用

internal static ILog log = LogManager.GetLogger(typeof(TemplateController));

确保您已[assembly: log4net.Config.XmlConfigurator]在 AssemblyInfo.cs 中列出

我发现在不添加该行的情况下，一切似乎都可以与 Log4Net 一起使用，但没有任何记录。

这是我的 Log4Net 配置。我使用彩色控制台附加程序以及滚动文件附加程序。

  <log4net>
        <appender name="Console" type="log4net.Appender.ColoredConsoleAppender">

            <mapping>
                <level value="INFO" />
                <foreColor value="Green,HighIntensity"/>
            </mapping>

            <mapping>
                <level value="DEBUG" />
                <foreColor value="Cyan,HighIntensity"/>
            </mapping>

            <mapping>
                <level value="WARN" />
                <foreColor value="Purple,HighIntensity"/>
            </mapping>

            <mapping>
                <level value="ERROR" />
                <foreColor value="Red,HighIntensity"/>
            </mapping>

            <mapping>
                <level value="FATAL" />
                <foreColor value="Yellow,HighIntensity"/>
            </mapping>

            <layout type="log4net.Layout.PatternLayout">
                <!-- Pattern to output the caller's file name and line number -->
                <conversionPattern value="%date,%5level,(%file:%line),%message%newline" />
            </layout>
        </appender>

        <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
            <file value="LOG.csv" />
            <appendToFile value="true" />
            <maximumFileSize value="1024MB" />
            <rollingStyle value="Date" />
            <datePattern value="yyyyMMdd" />

            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date,%5level,(%file:%line),%message%newline"  />
            </layout>
        </appender>

        <root>
            <level value="DEBUG" />
            <appender-ref ref="Console" />
            <appender-ref ref="RollingFile" />
        </root>
    </log4net>

请特别注意我的根元素是如何列出的 - 我认为您的配置文件问题可能存在。

试试我的配置，看看它是否适合你。如果它仍然不起作用，则需要解决其他问题。
