asp.net MVC实现文章的上一篇下一篇

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>
