Installer::OnBeforeInstall Method
Raises the BeforeInstall event.
Assembly: System.Configuration.Install (in System.Configuration.Install.dll)
Parameters
- savedState
- Type: System.Collections::IDictionary
An IDictionary that contains the state of the computer before the installers in the Installers property are installed. This IDictionary object should be empty at this point.
This method is called before the Install methods of the installers in this instance's InstallerCollection are called.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnBeforeInstall 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 InheritorsWhen overriding OnBeforeInstall in a derived class, be sure to call the base class's OnBeforeInstall method so that registered delegates receive the event.
