Best practice to implement a sort property

I have an api Get method which accepts sort property as a string. What is a best solution to handle it without using switch statement?

public ActionResult Index(string sortOrder)
{
   var students = from s in db.Students
                  select s;
   switch (sortOrder)
   {
      case "LastName":
         students = students.OrderByDescending(s => s.LastName);
         break;
      case "EnrollmentDate":
         students = students.OrderBy(s => s.EnrollmentDate);
         break;
      case "Birthday":
         students = students.OrderBy(s => s.Birthday);
         break;
      default:
         students = students.OrderBy(s => s.LastName);
         break;
   }
   return View(students.ToList());
}

Following code I found on microsoft's page, but I believe there is should be more elegant way to do it.
