排球计分Controller的实现

Posted 2020-09-24

1.首先实现的是Vollerballs的控制器：

利用entity framework自动生成控制器，用实体类VolleyballDB为模型和VolleyballContext为上下文自动创建Controller的方法和增删改查的视图。

2.之后再自定义一个Home控制器，实现把排球计分信息传入数据库，如下：

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
    {
        private VolleyballContext db = new VolleyballContext();
        public ActionResult Index()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Play(VolleyballDB db)
        {
            ViewData.Add("nameGame", db.gameName);
            ViewData.Add("nameA", db.teamA);
            ViewData.Add("nameB", db.teamB);
            return View();
        }
        [HttpPost]
        public ActionResult PlayRe(VolleyballDB volleyballdb)
        {
            if (ModelState.IsValid)
            {
                db.Volleyballs.Add(volleyballdb);
                db.SaveChanges();
                return RedirectToAction("../Volleyballs/Index");
            }
            return View("Play", volleyballdb);
        }

        public ActionResult About()
        {
            ViewBag.Message = "Your app description page.";

            return View();
        }

        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";

            return View();
        }
    }
}

3.把自动生成的Create视图和对应Action删除，并且修改相应指向。
