override this.IsEquivalentInstaller : System.Configuration.Install.ComponentInstaller -> bool
Public Overridable Function IsEquivalentInstaller (otherInstaller As ComponentInstaller) As Boolean

Parâmetros

otherInstaller
ComponentInstaller

O instalador a comparar.

Exemplos

O exemplo a seguir define uma classe MyInstallClass, que cria o log de eventos e copia as propriedades do componente de log de eventos para o EventLogInstaller objeto . Ele também verifica se ServiceInstaller o objeto pode lidar com o mesmo tipo de instalação EventLogInstallerque .

ServiceInstaller^ myServiceInstaller = gcnew ServiceInstaller;
// Check whether 'ServiceInstaller' object can handle the same
// kind of installation as 'EventLogInstaller' object.
if ( myEventLogInstaller->IsEquivalentInstaller( myServiceInstaller ) )
{
   Console::WriteLine( "'ServiceInstaller' can handle the same kind " +
      "of installation as EventLogInstaller" );
}
else
{
   Console::WriteLine( "'ServiceInstaller' can't handle the same " +
      "kind of installation as 'EventLogInstaller'" );
}

ServiceInstaller myServiceInstaller = new  ServiceInstaller();
// Check whether 'ServiceInstaller' object can handle the same
// kind of installation as 'EventLogInstaller' object.
if(myEventLogInstaller.IsEquivalentInstaller(myServiceInstaller))
{
   Console.WriteLine("'ServiceInstaller' can handle the same kind"
                     +" of installation as EventLogInstaller");
}
else
{
    Console.WriteLine("'ServiceInstaller' can't handle the same"
                 +" kind of installation as 'EventLogInstaller'");
}

Dim myServiceInstaller As New ServiceInstaller()
' Check whether 'ServiceInstaller' object can handle the same 
' kind of installation as 'EventLogInstaller' object.
If myEventLogInstaller.IsEquivalentInstaller(myServiceInstaller) Then
   Console.WriteLine("'ServiceInstaller' can handle the same kind" + _
                              " of installation as EventLogInstaller")
Else
   Console.WriteLine("'ServiceInstaller' can't handle the same" + _
                        " kind of installation as 'EventLogInstaller'")
End If

Comentários

Normalmente, IsEquivalentInstaller retornará true somente se esse instalador e o instalador especificados pelo otherInstaller parâmetro instalarem o mesmo objeto. Nesse caso, chamar o Install método ou Uninstall em qualquer instalador resulta no mesmo estado do sistema.
