log4net'not working' - 在子目录中配置

Question

My log4net configuration is stored in a config file located in a subdirectory of the application root.

Config\logging.config

The file is marked as an application content with attribute "Copy Always". Additionaly, in my AssemblyInfo.cs, I've declared the following line:

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Config\\logging.config", Watch = true)]

However, log4net doesn't log anything and it doesn't look like its initialized. How can I tell log4net where my configuration file is so it can initialize its components correctly?

Log4Net is designed to fail silently, on the grounds that no logging is preferable to taking down the application.

Most problems with log4net are (in my experience) related to file and permissions issues.

• Does the account under which your app runs have read access to the entire path to the config file?

• Is the "current working directory" what you think it is at the time the log4net config file is loaded?

To find out what the underlying problem is, use log4net's internall debugging:
