MVC系列博客之排球计分（六）Controller的实现（二）

上一篇博客没有完整的展现controller的代码，现在展示一下

HomeController

CoachController代码如下

public class CoachController : Controller
    {
        private gDBContext db = new gDBContext();

//

public ActionResult Index()
        {
            return View(db.Students.ToList());
        }

//

public ActionResult Details(int id = 0)
        {
            Score score = db.Students.Find(id);
            if (score == null)
            {
                return HttpNotFound();
            }
            return View(score);
        }

//

public ActionResult Create()
        {
            return View();
        }

//

[HttpPost]
        public ActionResult Create(Score Score)
        {
            if (ModelState.IsValid)
            {
                db.Students.Add(Score);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

return View(Score);
        }

public ActionResult Edit(int id = 0)
        {
            Score score = db.Students.Find(id);
            if (score == null)
            {
                return HttpNotFound();
            }
            return View(score);
        }

[HttpPost]
        public ActionResult Edit(Score score)
        {
            if (ModelState.IsValid)
            {
                db.Entry(score).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(score);
        }

//

public ActionResult Delete(int id = 0)
        {
            Score score = db.Students.Find(id);
            if (score == null)
            {
                return HttpNotFound();
            }
            return View(score);
        }

//

[HttpPost, ActionName("Delete")]
        public ActionResult DeleteConfirmed(int id)
        {
            Score gzscore = db.Students.Find(id);
            db.Students.Remove(score);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

protected override void Dispose(bool disposing)
        {
            db.Dispose();
            base.Dispose(disposing);
        }
    }

至此，controller已全部完成。
