如何在querystring asp.net mvc中删除空参数

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?

我最终使用客户端javascript过滤表单数据，这避免了任何不必要或空的查询参数。
