Get route value in a View and in a ASP tag helper

Hello,

On an ASP.NET MVC 6 project I have the following:

[Route("help/how-it-works")]
public IActionResult HowItWorks() {
   return View();
}

How can I get the route, e.g. "help/how-it-works" in the View and on an ASP Tag Helper?

Thank You,

Miguel
