How to retrieve an actionlink text in a controller?

I have a list of actionlink in my navbar like this

now i need to retrieve the link text in my controller to allocate some value in a property by comparing the value of the link text like this

 [HttpGet] public ActionResult Index() 

{

    Profile profile = new Profile();

    if(linktext=="Customer Profile") 

     {            

          profile.cust_supply_cat_id = 1; 

     } 

      else if (linktext == "Supplier Profile") 

         {

             profile.cust_supply_cat_id = 2;

         } 

      else if (linktext == "Publisher Profile")

          {        

              profile.cust_supply_cat_id = 3;

          } 

       return View(profile); 

}

How can i do it?
