【问题描述】:
为了制作更复杂的日志,我决定将 Log4Net 用于我的 WPF 桌面应用程序。它完美地工作,在“输出”处创建“调试”消息并将所有日志写入文件...
但是,如果我部署/安装它(使用 Visual Studio 的向导创建 .MSI 设置),它将停止工作。我在文件夹或计算机上的任何位置都找不到任何文件。
我正在使用 Caliburn.Micro 来组织我的代码。为了获得日志,我使用名为“Logging.cs”的公共静态类来“集中”它。
“Initialize()”中的代码现在是作为一种尝试的方式放置的,但它似乎没有做任何事情。
public static class Logging
{
//Declaration of the logger
/// <summary>
/// Logger for the Logging manager.
/// </summary>
private static log4net.ILog Logger = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
public static void Initialize()
{
log4net.Config.XmlConfigurator.Configure();
}

public static void Fatal(string message, Exception error, Type senderType)
{
//Defines 'type' in the log.
Logger = log4net.LogManager.GetLogger(senderType);
Logger.Fatal(message, error);
}

Logger.Fatal(message);

另外,这是我的 log4net 配置文件:
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="console" />
<appender-ref ref="file" />
</root>
<appender name="console" type="log4net.Appender.ColoredConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level %logger - [%message] // %exception%newline" />
</layout>
</appender>
<appender name="file" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="DesktopApp.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - [%message] // %exception%newline" />
</layout>
</appender>
<appender name="FileAppender" type="log4net.Appender.FileAppender">
<file value="log-file.txt" />
<appendToFile value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
</log4net>
在 AssemblyInfo.cs 中,我只是在末尾插入了这个:
[assembly: log4net.Config.XmlConfigurator(Watch = true,ConfigFile ="log4net.config")]
感谢您的宝贵时间,如果我可以添加更多详细信息,请发表评论。
P.S.:该软件安装在 AppData 中,因此不会出现文件权限问题,因为我正在使用另一个框架来自动更新应用程序。
P.S.2:我使用了 DebugView,在大部分看似随机的信息中,我发现了一个错误:
[5480] 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" />
还没有尝试修复它,只是保持这个问题是最新的。 (感谢瓦伦!)
【问题讨论】:
-
目标机器上无法创建DesktopApp.log有什么原因吗?
-
该软件安装在 Appdata 的本地文件夹中,因此不会出现权限/文件写入问题。我之前使用的是“手动”日志,并且运行顺利。
-
您可以使用 log4net 调试内部发生的事情。它可能会给您一些见解 关注此链接 - logging.apache.org/log4net/release/faq.html#internalDebug

谢谢。将检查出来。如果我发现任何新内容,我会更新。
