Installer.AfterRollback Event

Occurs after the installations of all the installers in the Installers property are rolled back.

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

public event InstallEventHandler AfterRollback

The following example demonstrates the AfterRollback event. It overrides the Install method and explicitly throws an ArgumentException so that the Rollback method is called. When the Rollback is completed, the AfterRollback event occurs and a message is displayed.

using System;
using System.Collections;
using System.ComponentModel;
using System.Configuration.Install;

// Set 'RunInstaller' attribute to true.
[RunInstaller(true)]
public class MyInstallerClass: Installer
{

   public MyInstallerClass() :base()
   {
      // Attach the 'AfterRollback' event. 
      this.AfterRollback += new InstallEventHandler(MyInstaller_AfterRollBack);
   }
   // Event handler for 'AfterRollback' event. 
   private void MyInstaller_AfterRollBack(object sender, InstallEventArgs e)
   {
      Console.WriteLine("AfterRollBack Event occured.");
   }

   // Override the 'Install' method. 
   public override void Install(IDictionary savedState)
   {
      base.Install(savedState);
      // Explicitly throw an exception so that roll back is called. 
      throw new ArgumentException("Arg Exception");
   }
   // Override the 'Commit' method. 
   public override void Commit(IDictionary savedState)
   {
      base.Commit(savedState);
   }
   // Override the 'Rollback' method. 
   public override void Rollback(IDictionary savedState)
   {
      base.Rollback(savedState);
   }
   public static void Main()
   {
      Console.WriteLine("Usage : installutil.exe Installer_AfterRollback.exe ");
   }
}
