How to get the Route Name ?

Hello:
In ASP .NET Core 1.x, I have the following:

 [HttpGet]
        [Route("GetLookupInfo"), Authorize("Bearer")]
        public IActionResult GetLookupInfo(string lookupName)
        {
            try
            {
...

Inside the method, I would like to get the Route name .. How would I get that programatically?
