如何在日志文件中编写消息？ [英] How do I write a message in my log file?

问题描述

下面是我在DotNet Framework 4.0中的C＃控制台应用程序的代码。它显示没有错误，但消息未写入日志文件。请帮我这里



App.Config： -

Below is my code for a C# console application in DotNet Framework 4.0. It shows no error but the message is not being written to log file. Please help me here

App.Config:-

<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net, Version=1.2.13.0" />
  </configSections>
<log4net>
    <appender name="FileAppender" type="log4net.Appender.FileAppender,log4net">
      <file value="D:\\TestProj\\TestLog.txt" />
      <appendToFile value="true" />
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
      </layout>
      <filter type="log4net.Filter.LevelRangeFilter">
        <levelMin value="INFO" />
        <levelMax value="FATAL" />
      </filter>
    </appender>

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



Class code:-


using log4net;
using log4net.Config;
public class Program
    {
 static void Main(string[] args)
        {
log4net.Config.XmlConfigurator.Configure();
            ILog log = log4net.LogManager.GetLogger(typeof(Program));
            log.Debug("This is a debug message");
            Console.WriteLine("Successfuly written into log !!!");
            Console.ReadLine();


        }
}

Hello Arun，



我不知道这是否是打字错误，但如下所示将配置更改为一个可以解决问题。

Hello Arun,

I don' know whether it's a typing mistake, but changing your configuration to one as shown below should take care of the problem.

<configuration>
    <configSections>
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler" />
    </configSections>
    <log4net>
        <appender name="FileAppender" type="log4net.Appender.FileAppender">
            <file value="D:\\TestProj\\TestLog.txt" />
            <appendtofile value="true" />
            <lockingmodel type="log4net.Appender.FileAppender+MinimalLock" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionpattern value="%date [%thread] %level %logger - %message%newline" />
            </layout>
            <filter type="log4net.Filter.LevelRangeFilter">
                <levelmin value="INFO" />
                <levelmax value="FATAL" />
            </filter>
        </appender>
 
        <root>
            <level value="DEBUG" />
            <appender-ref ref="FileAppender" />
        </root>
    </log4net>
</configuration>
