Public Methods

Method	Description
DatabaseTarget ( ) : System	Initializes a new instance of the DatabaseTarget class.
DatabaseTarget ( string name ) : System	Initializes a new instance of the DatabaseTarget class.
Install ( InstallationContext installationContext ) : void	Performs installation which requires administrative permissions.
IsInstalled ( InstallationContext installationContext ) : bool?	Determines whether the item is installed.
Uninstall ( InstallationContext installationContext ) : void	Performs uninstallation which requires administrative permissions.

Protected Methods

Method	Description
BuildConnectionString ( LogEventInfo logEvent ) : string	Build the connectionstring from the properties. Using ConnectionString at first, and falls back to the properties DBHost, DBUserName, DBPassword and DBDatabase
CloseTarget ( ) : void	Closes the target and releases any unmanaged resources.
Write ( AsyncLogEventInfo logEvents ) : void	Writes an array of logging events to the log target. By default it iterates on all events and passes them to "Write" method. Inheriting classes can use this method to optimize batch writes.
Write ( LogEventInfo logEvent ) : void	Writes the specified logging event to the database. It creates a new database command, prepares parameters for it by calculating layouts and executes the command.
