如何通过路由或URL重写更改URL名称？

Question

This is my original website when user browse it http://test/Template/PreviewWebPage/7 where the 7 is the id that passed into the database and get the data and display the webpage

I would like to ask how can I change the 7 into another name such as http://test/Template/PreviewWebPage/Hello where the word Hello still act as an id which will get the data from database.

The Hello word is also can be set by the user and change it such as Food or any other word which the user input

I am using asp.net mvc.

Here are my code for the PreviewWebPage

  public ActionResult PreviewWebPage(ShowSectionViewModel model, int id)
    {
        var item = dc.SECTION.Where(x => x.TEMPLATEID == id).OrderBy(x=>x.ORDERINDEX).ToList();
        var item2 = dc.SLIDESHOW.ToList();

        List<slideShowClass> slideShowClassList = new List<slideShowClass>();
        List<sectionClass> sectionClassList = new List<sectionClass>();
        sectionClass sc = new sectionClass();
        slideShowClass ssc = new slideShowClass();
        for (int i=0; i < item.Count(); i++){
            if (item[i].SECTIONTYPE != "Slide Show")
            {

                sc.SECTIONID = item[i].SECTIONID;
                sc.SECTIONIMAGE = item[i].SECTIONIMAGE;
                sc.SECTIONNAME = item[i].SECTIONNAME;
                sc.SECTIONTEXT = item[i].SECTIONTEXT;
                sectionClassList.Add(sc);
            }
            else
            {   
                for (int j = 0; j < item2.Count(); j++) {
                    if (item[i].SECTIONID == item2[j].SECTIONID)
                    {
                        ssc.SECTIONID = item[i].SECTIONID;
                        ssc.IMAGEFILE = item2[j].IMAGEFILE;
                        slideShowClassList.Add(ssc);
                    }

                }
            }
        }

        return View(new ShowSectionViewModel()
        {
            TemplateId = id,
            Sections = item,
            SlideShow = item2,
            sc = sectionClassList,
            ssc=slideShowClassList,

        });

    }

Sorry for my messy question as this is the first time I ask question at stakoverflow

Here are my code for the route config

routes.MapRoute( name: "PreviewWebPage", url: "Template/PreviewWebPage/{id}", defaults: new { controller = "Template", action = "PreviewWebPage", id =""} );

before start rewriting url you need to set up your work environnement : the a2enmod rewrite could perhaps be usefull in your case : https://www.digitalocean.com/community/tutorials/how-to-rewrite-urls-with-mod_rewrite-for-apache-on-ubuntu-16-04 . (That's for linux on which system are you ?)
