EventLogInstaller.Uninstall Method

Removes an installation by removing event log information from the registry.

Namespace:  System.Diagnostics
Assembly:  System.Configuration.Install (in System.Configuration.Install.dll)

public override void Uninstall(
	IDictionary savedState


Type: System.Collections.IDictionary
An IDictionary that contains the pre-installation state of the computer.

If the UninstallAction property value is Remove, the Uninstall method deletes the source and the associated log that the installer created if the Log and Source properties specified the creation of a new event log and source.

Typically, you do not call the methods of the EventLogInstaller from within your code; they are generally called only by the Installutil.exe (Installer Tool) in uninstall mode. The tool automatically calls the Uninstall method to restore the parts of the system that were affected by the installation to their pre-installation states. This includes deleting registry information that is associated with the event log being uninstalled.

An application's uninstall routine uses the project installer's Installer.Context property to automatically maintain information about the components that have already been uninstalled. This state information, which is passed to Uninstall as the savedState parameter, is continuously updated as the tool uninstalls each EventLogInstaller. Usually, it is not necessary for your code to explicitly modify this state information.
