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
SqlHelper.ClearBiaoRen();
//插入B的idB1  nameB1..
int numsA = 1;

//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
while (numsA <= 12)
{
//获取文本框名为idB1到idB12的值
int idA = int.Parse(Request["idA" + numsA]);
//获取文本框名为nameB1到nameB12的值
string name = Request["nameA" + numsA];

//排除name为空的情况
if (string.IsNullOrEmpty(name))
{
numsA++;
continue;
}
else
{
//name不为空插入 idB1  nameA1等进数据库

string sql = "insert into PersonA values(" + idA + ",'" + name + "')";
int a = SqlHelper.ExecuteNonQuery(sql, null);
if (a > 0)
{
ViewBag.IsSuccessA = "";
}
else
{
ViewBag.IsSuccessA = "A插入失败，未知错误";
}
}
numsA++;
}
//插入B的idB1  nameB1..
int numsB = 1;

//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
while (numsB <= 12)
{
//获取文本框名为idB1到idB12的值
int idB = int.Parse(Request["idB" + numsB]);
//获取文本框名为nameB1到nameB12的值

}
//string teamAName = Request["teamAName"];

StringBuilder sb = new StringBuilder();

return View("AddScore");
}

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

Admin Action方法

public ActionResult Admin()

ViewBag.teamBName = teamBName;
//获取是哪一个球员
string teamYuan = Request["teamYuan"];
//获取它是哪一种状态
string teamTai = Request["teamTai"];
//获取当前状态是否得分
string teamIsFen = Request["teamIsFen"];
