Log4Net File Appender Not Logging

Question

我的FileAppender无法正常工作。这可能不是一个权限的事情，因为我是本地管理员。

我已经启用了内部调试，并且没有从log4net收到任何错误或异常。

我的配置文件如下。 感谢

<log4net> 
     <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" > 
      <layout type="log4net.Layout.PatternLayout"> 
       <conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" /> 
      </layout> 
     </appender> 
     <appender name="FileAppender" type="log4net.Appender.FileAppender"> 
      <file value="C:\log-file.txt" /> 
      <appendToFile value="true" /> 
      <layout type="log4net.Layout.PatternLayout"> 
       <conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" /> 
      </layout> 
     </appender> 
     <root> 
      <level value="DEBUG" /> 
      <appender-ref ref="ConsoleAppender" /> 
      <appender-ref ref="FileAppender" /> 
     </root> 
    </log4net> 

登录的代码实际上是： -

public class Logger 
{ 
    private static readonly ILog defaultLog; 
    static Logger() 
    { 
     BasicConfigurator.Configure(); 
     defaultLog = LogManager.GetLogger("default"); 
    } 

    public static void Log(string errorMessage, Exception exception) 
    { 
     defaultLog.Error(errorMessage, exception); 
    } 
} 

Answer 1

根据您的描述我认为，您所使用的BasicConfigurator（只支持是ConsoleAppender）而不是XmlConfigurator。切换到XmlConfigurator应该可以解决您的问题。

Answer 2

有2个主要选项启用日志记录。有关更多详细信息，请参阅Configuration手册。

1. 使用XmlConfigurator.Configure()
2. 添加[assembly: log4net.Config.XmlConfigurator(Watch=true)]到AssemblyInfo.cs

BasicConfigurator.Configure（）只能写入控制台。

Answer 3

你试过RollingFileAppender吗？

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender" > 
    <file value="C:\log-file.txt" /> 
    <maximumFileSize value="10MB" /> 
    <maxSizeRollBackups value="10" /> 
    <rollingStyle value="Composite" /> 
    <appendToFile value="true" /> 
    <staticLogFileName value="true" /> 
    <layout type="log4net.Layout.PatternLayout"> 
    <conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" /> 
    </layout> 
</appender> 

Answer 4

我创造了这个辅助类

1）你可以启动尽可能多的附加器，你需要在整个应用程序，所以如果一个DLL调用的dll等既可以启动附加目的地和两个附加会工作。 2）你也可以关闭的appender和（如文件附加器的情况下），然后把它作为一个电子邮件
