Installer.Uninstall Method
Assembly: System.Configuration.Install (in system.configuration.install.dll)
public void Uninstall ( IDictionary savedState )
public function Uninstall ( savedState : IDictionary )
Not applicable.
Parameters
- savedState
An IDictionary that contains the state of the computer after the installation was complete.
-
If you override the Install method in a derived class, be sure to call the base class's Install method first in your derived method. The Install method calls the Install method of each installer contained in the Installers property of this instance. After the contained installers run, this method updates the IDictionary object (specified through the stateSaver parameter) to reflect the status of the installation. The IDictionary should be empty when passed to the Install method. If all the Install methods succeed, the Commit method is called. Otherwise, the Rollback method is called.
-
If you need to add installer instances to the Installers collection in the Install method, be sure to perform the same additions to the collection in the Uninstall method. However, you can avoid maintaining the collection in both methods if you add installer instances to the Installers collection in the class constructor for your custom installer.
The following example demonstrates the Uninstall method of Installer. The Uninstall method is overridden in the derived class of Installer.
// Override 'Uninstall' method of Installer class. public override void Uninstall( IDictionary mySavedState ) { if (mySavedState == null) { Console.WriteLine("Uninstallation Error !"); } else { base.Uninstall( mySavedState ); Console.WriteLine( "The Uninstall method of 'MyInstallerSample' has been called" ); } }
// Override 'Uninstall' method of Installer class.
public void Uninstall(IDictionary mySavedState)
{
if (mySavedState.Equals(null)) {
Console.WriteLine("Uninstallation Error !");
}
else {
super.Uninstall(mySavedState);
Console.WriteLine("The Uninstall method of 'MyInstallerSample'"
+" has been called");
}
} //Uninstall
