我有兩個單獨的xml文件用於配置log4Net。一個是登錄到一個文件，另一個是登錄到控制檯。我控制哪些文件被我的Global.asax.cs文件在Application_Start（）方法來讀取：log4Net沒有按預期記錄到控制檯
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
//Initialize Log4Net
XmlConfigurator.Configure(new System.IO.FileInfo("C:\\temp2\\DataTables_Examples\\DataTables_Examples\\Console.config"));
log.Info("Initializing Log4Net...");
Debug.WriteLine("MvcApplication - Initializing Log4Net...");
}
當我運行使用配置爲寫入文件的XML文件我的web應用程序，它完美罰款給我以下輸出：
2014-10-01 13:34:56,596 [6] ERROR CSED.Database
Error Number: 0
Error Code: -2147467259

這就好了。我故意更改了web.config中連接字符串的密碼，以便拋出此異常。然後我嘗試配置log4Net登錄到控制檯，我期望得到相同的輸出。不！爲控制檯
我的配置文件看起來像這樣：
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<!-- ConsoleAppender uses PatternLayout -->
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d [%t] %-5p %c %m%n" />
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="ConsoleAppender" />
</root>
</log4net>
</configuration>
沒有什麼不尋常那裏。
爲了比較，這是用於登錄到文件的配置。這工作：
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
<log4net>
<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender" >
<file value="C:\\temp2\\DataTables_Examples\\DataTables_Examples\\log.txt"/>
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d [%t] %-5p %c %m%n" />
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="LogFileAppender" />
</root>
</log4net>
</configuration>
然而，當我跑我的web應用程序，我得到如下：

的Console.config文件肯定是被log4net的讀入。那麼，爲什麼不打印輸出到控制檯，就像它在登錄文件時一樣？兩者的conversionPattern都相同。我所得到的只是控制檯底部的一行。我在某處失去了某些東西。
愚蠢的想法，但你有任何機會啓動您的控制檯應用程序的方式，重定向到另一個進程的標準輸出？ ConsoleAppender是唯一受影響的？ – samy 2014-10-01 21:31:47
