控制力的代码
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using MvcApplication1.Models; namespace MvcApplication1.Controllers { public class HomeController : Controller { // // GET: /Default1/ public ActionResult Index() { List<News> list = new NewsBF().Select(); return View(list); } public ActionResult Delete(string id) { try { int newsID = Convert.ToInt32(id); new NewsBF().Delete(newsID); return RedirectToAction("Index"); } catch { return RedirectToAction("Index", "Error"); } } public ActionResult Add() { News data = new News(); return View(data); } public ActionResult Insert(News data) { try { data.Time = DateTime.Now; new NewsBF().Insert(data); //送到数据库中去 return RedirectToAction("Index"); } catch { return RedirectToAction("Index", "Error"); } } public ActionResult Edit(string id) { int newsID = 0; try { newsID = Convert.ToInt32(id); News data = new NewsBF().Select(newsID); if (data != null) { return View(data); } else { return RedirectToAction("Index", "Error"); } } catch { return RedirectToAction("Index", "Error"); } } public ActionResult Update(News data) { try { //data.Time = DateTime.Now; new NewsBF().Update(data); return RedirectToAction("Index"); } catch { return RedirectToAction("Index", "Error"); } } } }
