How to remove empty parameters in querystring asp.net mvc

Question

So, I have a method that accepts a string and an object, the object has values that MVC translates into querystring parameters, my question is where and how can I get rid of the parameters that are empty so my url is cleaner.

Form:

  @using (@Html.BeginForm("Index", "ControllerName", FormMethod.Get, 
    new { enctype = "multipart/form-data", id = "form2" }))

   //Should I do a check in here for null values before getting the request?

Routing Link:

     routes.MapRoute
        (
            "Default",
            "{controller}/{action}/{id}",
            new {controller = "Home", action =        "Index", id = UrlParameter.Optional }
        );

Class:

class formModel{

 public string name {get;set;}
 public int? age {get;set;}
 public Guid? jobId{get;set;}
 public string Fullname {get;set;}

 }

Object properties:

     formModel{
                  name: "Mike",
                  age: 29,
                  jobId: null,
                  Fullname: ""
              }

Controller action:

    [HttpGet]
    public ActionResult Index(string sortByText, SearchFormModel formModel)
    {
        var model = new SomeViewModel();
        model.FormModel = formModel;
        //etc

        return View(model);
    }

Url:

example: http://www.domain.com/mycontroller?name=Mike&age=29&jobId=&Fullname=&Find=Find

How can I get rid of jobId and Fullname and Find?

One possibility is to make it nullable and not pass it. Another is to pass a dummy value like 0. — Dave Alperovich

I am looking into the routing of Global.asax now to see if I can do something there. — Rayshawn

It's not so much in the route as your Action Methods params. Accept a nullable id, or make id optional by defaulting it to 0. — Dave Alperovich

Yup, it works using an object, but I just want to get rid of the extra parameters that the user did not input in the search. — Rayshawn

I ended up filtering the form data with client-side javascript instead which avoids any unnecessary or empty query parameters.
