BeforeUninstall Event

Installer.BeforeUninstall Event

Occurs before the installers in the Installers property perform their uninstall operations.

Namespace: System.Configuration.Install
Assembly: System.Configuration.Install (in system.configuration.install.dll)

public event InstallEventHandler BeforeUninstall
/** @event */
public void add_BeforeUninstall (InstallEventHandler value)

/** @event */
public void remove_BeforeUninstall (InstallEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

The following example demonstrates the BeforeUninstall event. It is raised by the OnBeforeUninstall method.

// MyInstaller is derived from the class 'Installer'.
MyInstaller() : base()
{
   BeforeUninstall += new InstallEventHandler(BeforeUninstallEventHandler);
}
private void BeforeUninstallEventHandler(object sender, InstallEventArgs e)
{
   // Add steps to perform any actions before the Uninstall process.
   Console.WriteLine("Code for BeforeUninstallEventHandler"); 
}

// MyInstaller is derived from the class 'Installer'.
MyInstaller()
{
    this.add_BeforeUninstall(
        new InstallEventHandler(BeforeUninstallEventHandler));
} //MyInstaller

private void BeforeUninstallEventHandler(Object sender, InstallEventArgs e)
{
    // Add steps to perform any actions before the Uninstall process.
    Console.WriteLine("Code for BeforeUninstallEventHandler");
} //BeforeUninstallEventHandler
