The LoggingEvent type exposes the following members.

	Name	Description
	LoggingEvent(LoggingEventData)	Initializes a new instance of the LoggingEvent class using specific data.
	LoggingEvent(SerializationInfo, StreamingContext)	Serialization constructor
	LoggingEvent(Type, ILoggerRepository, LoggingEventData)	Initializes a new instance of the LoggingEvent class using specific data.
	LoggingEvent(Type, ILoggerRepository, LoggingEventData, FixFlags)	Initializes a new instance of the LoggingEvent class using specific data.
	LoggingEvent(Type, ILoggerRepository, String, Level, Object, Exception)	Initializes a new instance of the LoggingEvent class from the supplied parameters.

	Name	Description
	Domain	Gets the AppDomain friendly name.
	ExceptionObject	Gets the exception object used to initialize this event.
	Fix	The fixed fields in this event
	Identity	Gets the identity of the current thread principal.
	Level	Gets the Level of the logging event.
	LocationInformation	Gets the location information for this logging event.
	LoggerName	Gets the name of the logger that logged the event.
	MessageObject	Gets the message object used to initialize this event.
	Properties	Additional event specific properties.
	RenderedMessage	Gets the message, rendered through the RendererMap.
	Repository	The ILoggerRepository that this event was created in.
	StartTime	Gets the time when the current process started.
	StartTimeUtc	Gets the UTC time when the current process started.
	ThreadName	Gets the name of the current thread.
	TimeStamp	Gets the time of the logging event.
	TimeStampUtc	Gets UTC the time of the logging event.
	UserName	Gets the name of the current user.

	Name	Description
	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.)
	FixVolatileData	Obsolete. Fix instance fields that hold volatile data.
	FixVolatileData(Boolean)	Obsolete. Fixes instance fields that hold volatile data.
	FixVolatileData(FixFlags)	Fix the fields specified by the FixFlags parameter
	GetExceptionString	Returns this event's exception's rendered using the RendererMap.
	GetExceptionStrRep	Obsolete. Returns this event's exception's rendered using the RendererMap.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLoggingEventData	Gets the portable data for this LoggingEvent.
	GetLoggingEventData(FixFlags)	Gets the portable data for this LoggingEvent.
	GetObjectData	Serializes this object into the SerializationInfo provided.
	GetProperties	Get all the composite properties in this event
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	LookupProperty	Lookup a composite property in this event
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)
	WriteRenderedMessage	Write the rendered message to a TextWriter

	Name	Description
	HostNameProperty	The key into the Properties map for the host name value.
	IdentityProperty	The key into the Properties map for the thread identity value.
	UserNameProperty	The key into the Properties map for the user name value.

When an affirmative decision is made to log then a LoggingEvent instance is created. This instance is passed around to the different log4net components.

This class is of concern to those wishing to extend log4net.

Some of the values in instances of LoggingEvent are considered volatile, that is the values are correct at the time the event is delivered to appenders, but will not be consistent at any time afterwards. If an event is to be stored and then processed at a later time these volatile values must be fixed by calling [M:FixVolatileData()]. There is a performance penalty for incurred by calling [M:FixVolatileData()] but it is essential to maintaining data consistency.
