ASP.NET MVC 排球计分程序 （六）HomeController代码和一些解释

Index Action方法 （默认进入的主页）

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

AddPerson Action方法（单击主页提交 将交到AddPerson里来处理数据，并将队员 名字插入数据库）

 

 public ActionResult AddPerson()
        {
            //获取填入的衣服编号和名字 并将其写入数据库
            //编号idA1  nameA1

            //将十二个队员全部插入数据库 总共有十二个文本框 执行<=12次的循环 插入值

这个Action主要写了插入名字到对应的PersonA  PersonB 数据库 

弹出新的界面应显示的一些内容 

如队名 根据自己在数据库中插入的内容而生成的下拉列表  队名的传递也可以使用Cookie 和session这里不做解释

ViewBag.名字 可以用来传递数据

在视图中用@VieWBag名字  可以获取到自己传递的值 详情可以了解一下Rezor语法等
