由于这个东西的原理没有什么难的(只是实现的时候有少量的坑),故直接上代码以便查阅。另:本文给出的Action附送了点击量统计。

public ActionResult SingleNews(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            var news = storeDB.articles.Find(id);

            var prev = storeDB.articles.Where(p => p.ID<id).OrderByDescending(p => p.ID).Take(1).ToList();
            var next = storeDB.articles.Where(p => p.ID>id).Take(1).ToList();
            
            if(prev.Count>0)
            {
                ViewBag.preTitle = prev.ElementAt(0).title;
                ViewBag.preId = prev.ElementAt(0).ID;
            }
            else
            {
                ViewBag.preTitle = "没有了";
                ViewBag.preId = id;
            }

            if (next.Count>0)
            {
                ViewBag.nextTitle = next.ElementAt(0).title;
                ViewBag.nextId = next.ElementAt(0).ID;
            }
            else
            {
                ViewBag.nextTitle = "没有了";
                ViewBag.nextId = id;
            }
            
            //记录点击量
            if(news!=null)
            {
                news.clickCount += 1;
                storeDB.Entry(news).State = EntityState.Modified;
                storeDB.SaveChanges();    
            }
            
            return View(news);
        }

视图中的相关代码:

<div>
  <label>上一篇:</label>@Html.ActionLink((string)ViewBag.preTitle, "NewsContent", new { id=ViewBag.pre})
  <label>下一篇:</label>@Html.ActionLink((string)ViewBag.nextTitle, "NewsContent", new { id=ViewBag.next})
</div>
