log4net的输出到我的文档 [英] Log4net output to My Documents

问题描述

在我们的C＃应用​​程序，我们将文件写入 Environment.GetFolderPath（Environment.SpecialFolder.MyDocuments）。我们log4net的日志文件应该去那里了，所以我们定义 application.conf 如下：

In our C# app, we write files to Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments). Our log4net logfile should go there too, so we've defined application.conf as follows:

<appender name="LogFile" type="log4net.Appender.RollingFileAppender">
  <appendToFile value="true"/>
  <file value="%USERPROFILE%\My Documents\MyApp\log.txt"/>
  ...snip...
</appender>

这工作，直到我们有一个非英语Windows的PC上运行英寸因为那样的话， SpecialFolder.MyDocuments 指向文件夹 Mijn Documenten ，而日志还是到我的文档。随之而来的混乱，因为现在我们的文件是在两个地方。

This works, until we run in on a PC which has a non-English Windows. Because then, SpecialFolder.MyDocuments points to the folder Mijn Documenten, while the log still goes to My Documents. Confusion ensues, because now our files are in two places.

我想我的日志写入真正的我的文档文件夹中。我该怎么做呢？

I want to write my log to the "real" My Documents folder. How do I do this?

• 我试图找到像％USERPROFILE％，但似乎并不存在一个我的文档。


• 有一个定义的我的文档的真实位置的注册表项，但它从 application.conf 。



• 我试图以编程方式重写我的appender的文件参数，像这样的：

• I tried to find an environment variable like %USERPROFILE%, but there doesn't seem to exist one for My Documents.
• There's a registry key that defines the true location of My Documents but it's not accessible from application.conf.

• I tried to override the File parameter of my appender programmatically, like this:

public static void ConfigureLogger()
{
    XmlConfigurator.Configure();

    Hierarchy hierarchy = (Hierarchy)log4net.LogManager.GetRepository();
    foreach (var appender in hierarchy.Root.Appenders)
    {
        if (appender is FileAppender)
        {
            var fileAppender = appender as FileAppender;
            var logDirectory = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "MyApp");
            var pathElements = fileAppender.File.Split(Path.DirectorySeparatorChar);
            var logFileName = pathElements.Last();
            var fullLogFilePath = Path.Combine(logDirectory, logFileName);
            fileAppender.File = fullLogFilePath;
        }
    }
}

这也不起作用：当我检查我的记录器的内部，在文件属性高兴地报告 Mijn Documenten ，但在平均时间日志还是去我的文档。

This doesn't work either: when I inspect the internals of my logger, the File property happily reports Mijn Documenten, but in the mean time the logs still go to My Documents.

我运行的想法！

推荐答案

更改行

<file value="%USERPROFILE%\My Documents\MyApp\log.txt"/>

到

to

<file type="log4net.Util.PatternString" value="%envFolderPath{MyDocuments}\MyApp\log.txt" />
