InstallerOnBeforeUninstall Method

Raises the BeforeUninstall event.

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

protected virtual void OnBeforeUninstall(
	IDictionary savedState
virtual void OnBeforeUninstall(
	IDictionary^ savedState
abstract OnBeforeUninstall : 
        savedState:IDictionary -> unit
override OnBeforeUninstall : 
        savedState:IDictionary -> unit
Protected Overridable Sub OnBeforeUninstall (
	savedState As IDictionary



An IDictionary that contains the state of the computer before the installers in the property uninstall their installations.

This method is called before the Uninstall methods of the installers in this instance's InstallerCollection are uninstalled.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnBeforeUninstall method allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

When overriding OnBeforeUninstall in a derived class, be sure to call the base class's OnBeforeUninstall method so that registered delegates receive the event.
