SimpleObjectAppender

Simple log4net extensions - extract any data that you want from your object.

The idea of the ObjectAppender was originally brought by @eliranmoyal and @DimaRabkin.

This specific project started as a simple and abstract example of how can this be achieved and I decided to upload it.

The SimpleObjectAppender gives you the ability to:

// Say you have this class:classPerson{publicintAge{get;set;}publicstringName{get;set;}}

// So INSTEAD of logging like this:logger.Info(string.Format("Person details - Name:{0}, Age:{1}",person.Name,person.Age))// You would do this:
logger.Info(person);

And choose which properties of the class you want to log and in which format inside your log4net configuration.

Project contains:

• SimpleObjectForwarder - Forwarding Appender.
• SimpleObjectConverter - Layout Converter.
• SimpleObjectConsoleAppender - Console Appender.

---

SimpleObjectForwarder

A log4net forwarding appender (example) which will format your object as string and send it to next appenders.

Usage example:

 <appendername="objectForwarder"type="SimpleObjectAppender.SimpleObjectForwarder, SimpleObjectAppender">
<appender-refref="nextAppenderName" />
<Details>
<Property>Prop1Name</Property>
<Property>Prop2Name</Property>
</Details>
</appender>

More Tags:

• Separator - The separator string between each property. (default: ", ")
• EqualsSymbol - The string which separate between property name and value. (default: ":")
• IgnoreNotExists - Ignore the whole key+value if the property doesn't exists. (default: true)
• Descriptor - If you are pro and want custom property extractor.

SimpleObjectConverter

A log4net pattern layout converter (example of creating and using converter) which will give you the ability to format the message with your own object properties.

Usage example:

 <appendername="MyConsoleAppender"type="log4net.Appender.ConsoleAppender">
<layouttype="log4net.Layout.PatternLayout">
<Converter>
<namevalue="object" />
<typevalue="SimpleObjectAppender.SimpleObjectConverter, SimpleObjectAppender" />
</Converter>
<conversionPatternvalue="%-4timestamp %-5level %logger - Name is:%object{Name}, age:%object{Age}%newline" />
</layout>
</appender>

SimpleObjectConsoleAppender

A log4net console appender (example) - just a console appender, the configuration is exactly as the forwarding appender except that this appender will just write to you console instead of forwarding the message.

Usage example:

 <appendername="objectConsoleAppender"type="SimpleObjectAppender.SimpleObjectConsoleAppender, SimpleObjectAppender">
<Details>
<Property>prop1</Property>
<Property>prop2</Property>
</Details>
</appender>
