从Log4Net配置获取值 [英] Getting values from Log4Net configuration

问题描述

我已经通过扩展AppenderSkeleton类实现了自定义log4net附加程序.它就像任何人都可以要求的那样简单，并且运行良好.

I have implement a custom log4net appender by extending the AppenderSkeleton-class. It was as simple as anyone could ask for and works perfectly.

我的问题是我必须对一些值进行硬编码，我想将它们从我的代码中删除到附加程序的配置中.由于log4net知道它是如何配置的，因此我认为应该有一种方法可以询问log4net的配置.

My problem is that I had to hardcode a few values and I'd like to remove them from my code to the configuration of the appender. Since log4net knows how it is configured I think there should be a way to ask log4net for it's configuraion.

我的附加程序可能看起来像这样:

My appender could look something like this:

<appender name="MyLogAppender" type="xxx.yyy.zzz.MyLogAppender">
      <MyProperty1>property</MyProperty1>
      <MyProperty2>property</MyProperty2>
      <MyProperty3>property</MyProperty3>
</appender>

如何获取MyProperty1-3的值，以便可以在Appender中使用它?

How to get the value of MyProperty1-3 so I can use it inside my Appender?

先谢谢了 罗恩(Roalnd)

Thanks in advance Roalnd

推荐答案

这取决于类型，但是对于简单类型，您可以执行以下操作:

It depends a bit on the type but for simple types you can do the following:

定义这样的属性:

// the value you assign to the field will be the default value for the property
private TimeSpan flushInterval = new TimeSpan(0, 5, 0);

public TimeSpan FlushInterval
{
     get { return this.flushInterval; }
     set { this.flushInterval = value; }
}

您可以进行以下配置:

<appender name="MyLogAppender" type="xxx.yyy.zzz.MyLogAppender">
    <flushInterval value="02:45:10" />
</appender>

这当然适用于字符串，布尔值，整数和时间跨度.

This certainly works for string, bool, int and TimeSpan.

注意:如果您的设置需要激活某些逻辑(例如创建计时器)，则可以在ActivateOptions方法中实现.

Note: If your settings requires some logic to be activated (e.g. create a timer) then you can implement this in the ActivateOptions method.
