C# 在mvc4中重写动态生成的url

我的方案是重写基于用户登录动态生成的url。例如，我的url是“mywebsite.com/controllername/methodname？id1=venkatesh%2Fevents”，我想将此url更改为“mywebsite.com/venkatesh/events。我尝试了几种方案，但没有找到合适的解决方案。我尝试了下面的代码，但它没有给出正确的答案，请建议

namespace MvcApplication3.Controllers
{

    [RouteArea("area")]
    [RoutePrefix("event",Precedence=1)]
    [RoutePrefix("student", Precedence = 2)]
    public class Default1Controller : Controller
    {
        //
        // GET: /Default1/
        [GET("venkatesh")]
      [GET("venkatesh-event",IgnoreAreaUrl=true)]
        public ActionResult Index()
        {

            ViewBag.info = "This is index method";
            return View();
        }

        //
        // GET: /Default1/Details/5
        [GET("event{id}")]
        public ActionResult Details(int id)
        {
            ViewBag.info = "This is details method"+id;
            return View();
        }
