Comentarios

Si la llamada al Contains método devuelve true, puede tener acceso al elemento especificado en la colección mediante la sintaxis DtsProperties[index]. Si Contains el método devuelve false, esta propiedad produce una excepción. En C#, esta propiedad es el indizador para la clase DtsProperties.
