问题
I am using log4net for logging. My logging configuration is stored in a separate file.
Web.Config:ConfigSections
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
Specifying my config file in AssemblyInfo.cs
[assembly: log4net.Config.XmlConfigurator(ConfigFile="Log4Net.config", Watch = true)]
And when I initialize my LogManager, I get this error
"System.TypeLoadException"
message: Could not load type 'log4net.Config.Log4NetConfigurationSectionHlandler' from assembly 'Log4net'.
Yes it says "Log4NetConfigurationSectionHlandler'", it is not a typo
and later, this error
An error occurred creating the configuration section handler for log4net: Could not load type 'log4net.Config.Log4NetConfigurationSectionHlandler' from assembly 'Log4net'.
Edit: Tried Mauricio Scheffer's suggestion
got
log4net:ERROR XmlConfigurator: 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" />
回答1:
If you have your config in a separate log4net.config file you don't need the sectionHandler. Remove it.
You're also probably calling XmlConfigurator.Configure() somewhere in your code. Remove that as well.
