The Logger type exposes the following members.

	Name	Description
	Logger	This constructor created a new Logger instance and sets its name.

	Name	Description
	Additivity	Gets or sets a value indicating if child loggers inherit their parent's appenders.
	Appenders	Get the appenders contained in this logger as an ICollection.
	EffectiveLevel	Gets the effective level for this logger.
	Hierarchy	Gets or sets the Hierarchy where this Logger instance is attached to.
	Level	Gets or sets the assigned Level, if any, for this Logger.
	Name	Gets the logger name.
	Parent	Gets or sets the parent logger in the hierarchy.
	Repository	Gets the ILoggerRepository where this Logger instance is attached to.

	Name	Description
	AddAppender	Add newAppender to the list of appenders of this Logger instance.
	CallAppenders	Deliver the LoggingEvent to the attached appenders.
	CloseNestedAppenders	Closes all attached appenders implementing the IAppenderAttachable interface.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	ForcedLog(LoggingEvent)	Creates a new logging event and logs the event without further checks.
	ForcedLog(Type, Level, Object, Exception)	Creates a new logging event and logs the event without further checks.
	GetAppender	Look for the appender named as name
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsEnabledFor	Checks if this logger is enabled for a given Level passed as parameter.
	Log(LoggingEvent)	This is the most generic printing method that is intended to be used by wrappers.
	Log(Level, Object, Exception)	This is the most generic printing method. This generic form is intended to be used by wrappers
	Log(Type, Level, Object, Exception)	This generic form is intended to be used by wrappers.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RemoveAllAppenders	Remove all previously added appenders from this Logger instance.
	RemoveAppender(String)	Remove the appender passed as parameter form the list of appenders.
	RemoveAppender(IAppender)	Remove the appender passed as parameter form the list of appenders.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Internal class used to provide implementation of ILogger interface. Applications should use LogManager to get logger instances.

This is one of the central classes in the log4net implementation. One of the distinctive features of log4net are hierarchical loggers and their evaluation. The Hierarchy organizes the Logger instances into a rooted tree hierarchy.

The Logger class is abstract. Only concrete subclasses of Logger can be created. The ILoggerFactory is used to create instances of this type for the Hierarchy.
