Installer.BeforeInstall Event

Occurs before the Install method of each installer in the installer collection has run.

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

public event InstallEventHandler BeforeInstall
/** @event */
public void add_BeforeInstall (InstallEventHandler value)

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

JScript supports the use of events, but not the declaration of new ones.

The following example demonstrates the BeforeInstall event. It is raised by the OnBeforeInstall method.

// MyInstaller is derived from the class 'Installer'.
MyInstaller() : base()
{
   BeforeInstall += new InstallEventHandler(BeforeInstallEventHandler);

private void BeforeInstallEventHandler(object sender, InstallEventArgs e)
{
   // Add steps to perform any actions before the install process.
   Console.WriteLine("Code for BeforeInstallEventHandler"); 


// MyInstaller is derived from the class 'Installer'.
MyInstaller()
{
    this.add_BeforeInstall(
        new InstallEventHandler(BeforeInstallEventHandler));
 //MyInstaller

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