未创建日志文件

本文关键字:文件 日志 创建 | 更新日期: 2023-09-27 18:00:19

我需要在本地文件夹中生成日志文件。我在控制台应用程序中使用以下代码生成日志文件。但日志文件没有创建。是否需要任何更改?

我在应用程序配置文件中使用以下代码

<?xml version="1.0" encoding="utf-8" ?>    
<configuration>    
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
  <!-- <log4net configSource="log4net.config" /> -->
  <log4net>
    <appender name="FileAppender" type="log4net.Appender.FileAppender">
      <file value="Log4NetApplicationLog.log" />
      <appendToFile value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
      <layout type="log4net.Layout.PatternLayout">
        <param name="Header" value="[Header]'r'n" />
        <param name="Footer" value="[Footer]'r'n" />
        <param name="ConversionPattern" value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>
    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="Log4NetApplicationRollingLog.log" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="1MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
      </layout>
    </appender>
    <root>
      <level value="ALL" />
      <appender-ref ref="FileAppender" />
      <appender-ref ref="ConsoleAppender"/>
      <appender-ref ref="RollingFileAppender"/>
    </root>
  </log4net>
  <appSettings>
    <add key="KeyOne" value="ValueOne"/>
  </appSettings>
</configuration>

我将以下文件用于类文件

 class Program
    {
        private static readonly ILog Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
        static void Main(string[] args)
        {
            XmlConfigurator.Configure(); //only once
            Log.Debug("Application is starting");
            Console.WriteLine("Test Line");
            var testClass = new TestClass();
            testClass.LogSomething();
            Log.Debug("Application is ending");
            Console.Read();
        }
        public class TestClass
        {
            private static readonly ILog Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
            public void LogSomething()
            {
                for (int i = 0; i < 2; i++)
                {
                    Log.InfoFormat("CurrentTime is [{0}]", DateTime.Now.ToString("yyyy.MM.dd-hh.mm.ss~fff"));
                }
            }
        }
    }

未创建日志文件

我把这个书签放在手边,当我无法让日志记录工作时,我会引用它——它通常会成为一个配置问题。。。

基本上,你可以将其添加到你的appSettings 中

<add key="log4net.Internal.Debug" value="true"/>

然后在</configuration> 之前添加以下内容

<system.diagnostics>
  <trace autoflush="true">
    <listeners>
      <add 
        name="textWriterTraceListener" 
        type="System.Diagnostics.TextWriterTraceListener" 
        initializeData="C:'temp'log4net.txt" />
    </listeners>
  </trace>
</system.diagnostics>

运行您的应用程序,然后转到C:''temp''log4net.txt,查看log4net是否抛出任何错误。这通常有助于查明问题的原因。
