In asp.net-mvc, Is there a way to do "reverse" model binding to convert my C# object back to "querystring" text?

I have a custom javascript on the client side that I use to build up a querystring and pass over to my asp.net-mvc controller

   var templateQueryString = BuildTemplate();

    $.ajax({
      url: '/MyController/Save?' + templateQueryString,
      type: 'post',
      dataType: 'json',
      success: function (data) {
      }
    }

and on my controller all of the properties leverage the model binding so it comes in as a single object on the server side. NOTE: that this is a pretty complex object with arrays and arrays of sub objects:

public ActionResult Save(MyTemplate template)
{
}

the issue now is that I need to be able to convert from my C# object back to a string that represents "myTemplateQueryString" on the client side.

Is there any recommended way to take an object and do the "reverse" model binding. They key here is that it generates a string that I could use as a query string again in the future to pass into another asp.ent-mvc controller action.
