Log4Net错误: log4net中基于文件的登录无法工作

Question

我正在尝试将log4net记录器实现到我的基于application.file的WPF登录，而不是为我工作。

我读过很多其他的问题和答案，但我还没能解决.这就是我遇到的错误：

log4net:ERROR Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the <log4net> and <configSections> elements. The configuration section should look like: <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />

log4net.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <log4net>
    <root>
      <level value="ALL" />
      <appender-ref ref="console" />
      <appender-ref ref="file" />      
    </root>
    <appender name="console" type="log4net.Appender.ConsoleAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date %level %logger - %message%newline" />
      </layout>
    </appender>
    <appender name="file" type="log4net.Appender.RollingFileAppender">
      <file value="${LocalAppData}//myapp//Logs//myappplog.log" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="5" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date - %message%newline" />
      </layout>
    </appender>  
  </log4net>
</configuration>

Assemblyinfo.cs

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

App.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
        <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </configSections>
    <log4net configSource="log4net.config" />
  <entityFramework>

mainview.xaml.cs公共部分类MainView : UserControl {

   private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
    
    public MainView()
    {
        InitializeComponent();
        Getloaded();
    }
    public void Getloaded()
    {
        log4net.Config.XmlConfigurator.Configure();
        try
        {
            log.Info("        =============  Started Application  =============        ");

        }
        catch(Exception ex)
        {
        }
    }

您正在声明log4net，但没有添加它。它会导致.net上升这个错误。您应该从配置文件中删除log4net节声明，并将配置文件名(log4net.config)传递到log4net.Config.XmlConfigurator.Configure("log4net.config");方法中，或者直接将log4net配置部分添加到App.config中(<log4net configSource="log4net.config" /> )。我相信第二种方式对你来说是最好的。

下面是配置在本例中的样子。

<configSections>
     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />     
      <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<log4net configSource="log4net.config" />
...
