从log4net配置部分访问appSettings配置值 [英] Accessing appSettings config values from log4net config section

问题描述

有人知道是否可以从同一文件中的log4net config部分的配置文件的appSettings部分访问键/值(不使用代码)吗?

Does anyone know if it's possible to access key/values from the appSettings section of a config file from the log4net config section in the same file (without using code)?

例如:

<appSettings>
    <add key="Environment" value="DEV" />
    <!-- etc -->
</appSettings>
<log4net>
    <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
    <file value="${APPDATA}\MyApp\${Environment}\MyApp.log" />
    <!-- etc -->
</log4net>

关于这方面似乎没有任何文档，所以我不希望...如果所有其他方法都失败了，我只需将"DEV"添加到文件值中，然后将其与appSettings的Environment变量一起替换即可

There doesn't seem to be any documentation on this, so I'm not hopeful... If all else fails, I'll just add "DEV" into the file value and subst it alongside the appSettings' Environment variable.

预先感谢

推荐答案

感谢@wageoghe的帮助.最后，我决定再次将环境值添加到配置文件中(为简单起见):

Thanks @wageoghe for your help. In the end, I decided to just add the environment value into the config file again (for simplicity):

<log4net>
    <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
    <file value="${APPDATA}\MyApp\DEV\MyApp.log" />
    <!-- etc -->
</log4net>
