log4net不登录Windows事件查看器

Question

我想使用log4net登录Windows事件查看器.
我创建了一个控制台应用程序(.NET Framework 4),我添加了参考log4net.dll,我将以下代码放在我的App.config中:

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

<log4net>
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
  </layout>
</appender>
<root>
  <level value="ALL"/>
  <appender-ref ref="EventLogAppender"/>
</root>
</log4net>

<startup><supportedRuntime version="v2.0.50727"/></startup>
</configuration>

我把以下代码:

class Program
{
    static void Main(string[] args)
    {
        log4net.ILog log = log4net.LogManager.GetLogger(typeof(Program));
        log.Error("test error", new Exception("error's exception", new Exception("error's innerexception")));

        Console.Read();
    }
}

它没有记录,没有任何反应,为什么？

谢谢

Answer 1

你需要调用configure.

更改:

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

至

[assembly: log4net.Config.XmlConfigurator(Watch = true)] 

当你指定ConfigFile = "App.config"它将寻找App.config但你的文件名将是[FileName].Config.

Answer 2

您需要从log4net库调用XmlConfigurator.Configure来初始化它.(见下文)

class Program
{
    static void Main(string[] args)
    {
        // you need this
        XmlConfigurator.Configure();
        log4net.ILog log = log4net.LogManager.GetLogger(typeof(Program));
        log.Error("test error", new Exception("error's exception", new Exception("error's innerexception")));

        Console.Read();
    }
}
