c# - 让 log4net 工作

Question

我已经为使用记录器编写了一个包装器类，并且因为我以前从未使用过 log4net(我在工作中使用 log4c++，但它已经配置好了，我从来不需要弄乱它)，
我不知道如何正确配置它并使其正常工作...

这是包装类的当前源代码:

using System.Text;
using log4net;
using log4net.Appender;
using log4net.Config;
using log4net.Layout;

namespace GotLoggingService
{
    public sealed partial class LoggerManager
    {
        private ILog Logger { get; }

        #region Info Methods

        public void Info(string message)
        {
            Logger.Info(message);
        }

        public void InfoFormat(string format, params object[] args)
        {
            Logger.InfoFormat(format, args);
        }

        #endregion

        #region Debug Methods

        public void Debug(string message)
        {
            Logger.Debug(message);
        }

        public void DebugFormat(string format, params object[] args)
        {
            Logger.DebugFormat(format, args);
        }

        #endregion

        #region Warn Methods

        public void Warn(string message)
        {
            Logger.Warn(message);
        }

        public void WarnFormat(string format, params object[] args)
        {
            Logger.WarnFormat(format, args);
        }

        #endregion

        #region Error Methods

        public void Error(string message)
        {
            Logger.Error(message);
        }

        public void ErrorFormat(string format, params object[] args)
        {
            Logger.ErrorFormat(format, args);
        }

        #endregion

        #region Fatal Methods

        public void Fatal(string message)
        {
            Logger.Fatal(message);
        }

        public void FatalFormat(string format, params object[] args)
        {
            Logger.FatalFormat(format, args);
        }

        #endregion

        #region Getters

        public static LoggerManager GetLogger(string name)
        {
            return new LoggerManager(name);
        }

        public static LoggerManager GetLogger(string name, LoggerManager parent)
        {
            return new LoggerManager(name, parent);
        }

        public static LoggerManager GetRootLogger()
        {
            return RootLooger;
        }

        #endregion
    }

    // Manage stuff here
    public sealed partial class LoggerManager
    {
        private const string FORMAT = "%timestamp  %-5level %logger %ndc - %ndc %message%newline";

        // Initializes root logger
        private LoggerManager()
        {
            Logger = LogManager.GetLogger(ROOT_LOGGER_NAME);
            BasicConfigurator.Configure(new FileAppender
            {
                AppendToFile = true,
                Encoding = Encoding.UTF8,
                File = "C:/log.txt",
                ImmediateFlush = true,
                Layout = new PatternLayout(FORMAT)
            });
        }

        private LoggerManager(string name) : this(name, GetRootLogger())
        {
        }

        private LoggerManager(string name, LoggerManager parent)
        {
            Logger = GetILog(name, parent);
        }

        private const string ROOT_LOGGER_NAME = "root";

        private static readonly LoggerManager RootLooger = new LoggerManager();

        private static ILog GetILog(string name, LoggerManager parent)
        {
            return LogManager.GetLogger(GetLoggerName(name, parent.Logger.Logger.Name));
        }

        private static string GetLoggerName(string name, string parent = ROOT_LOGGER_NAME)
        {
            StringBuilder nameBuilder = new StringBuilder();
            nameBuilder.AppendFormat("{0}.{1}", LogManager.GetLogger(parent).Logger.Name, name);
            return nameBuilder.ToString();
        }
    }
}

如您所见，我已尝试使用 BasicConfigurator 进行配置，并为其提供 FileAppender。我试过记录东西，但它没有向文件添加任何内容……这是我如何使用记录器包装器的一个简短示例:

using GotLoggingService;

namespace trythelog
{
    class LoggerTry
    {
        private LoggerManager logger;

        public static void Main(string[] args)
        {
            LoggerTry logger = new LoggerTry();
        }

        public LoggerTry()
        {
            logger = LoggerManager.GetLogger("some-logger");
            logger.Info("this is a log message");
        }
    }
}

基本上我要说的就是这些...感谢阅读，如果你能指出我搞砸的地方，我会很高兴。

我现在使用 App.Config 而不是 BasicConfigurator

这是 app.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
    </startup>

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

  <log4net>

      <level value="DEBUG"/>
      <appender-ref ref="RollingLogFileAppender"/>

        <conversionPattern value="%date %-5level %logger %ndc - %ndc %message%newline" />
      </layout>
    </appender>

  </log4net>
</configuration>

尝试:

代码

using log4net;
...

 static void Main(string[] args)
        {
            log4net.Config.XmlConfigurator.Configure(); // Missing!!?

            ILog log = LogManager.GetLogger("MyLogger");
            log.Info("message");

App.Config 或 Web.Config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>   <!-- must be the first child -->
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
  </configSections>

   ...

  <log4net>
    <logger name="MyLogger">
      <level value="INFO" />
      <appender-ref ref="RollingLogFileAppender" />
    </logger>


    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <file value="logs/" /> <!--YOUR PATH-->
      <datePattern value="yyyyMMdd'.log'" />
      <staticLogFileName value="false" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="5MB" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
      </layout>
    </appender>

  </log4net>


</configuration>
