一、需求分析
实现效果
二、实现步骤
步骤一：新建项目--->Web---->空模板
步骤二：添加控制器
步骤三：根据控制器名称添加视图
步骤四：添加Models模型 编写具体的方法
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace MVCDemo.Models
{
public class Calculator
{
public int getAVG(int sumScore,int sumSubject)
{
return sumScore / sumSubject;
}
}
}
步骤五：编写视图，具体展示的内容
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>CalculatorView</title>
</head>
<body>
<form method="post" action="/Calculator/Calculate">
计算平均成绩<br/>
总成绩：<input type="text" name="sumScore" /> <br/>
总科目：<input type="text" name="sumSubject" /><br/>
<input type="submit" value="开始计算"/><br/>
@ViewData["avgScore"]
</form>
</body>
</html>
步骤六：编写控制器活动方法
using MVCDemo.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MVCDemo.Controllers
{
public class CalculatorController : Controller
{
// GET: Calculator
public ActionResult Index()
{
return View("CalculatorView");
}
public ActionResult Calculate()
{
//[1]获取数据
int sumScore = Convert.ToInt32(Request.Params["sumScore"]);
int sumSubject = Convert.ToInt32(Request.Params["sumSubject"]);
//[2]处理数据
Calculator objCal = new Calculator();
int avgScore = objCal.getAVG(sumScore, sumSubject);
//[3]返回数据
ViewData["avgScore"] = "平均成绩为：" + avgScore;
return View("CalculatorView");
}
}
}
步骤七：修改路由
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
namespace MVCDemo
{
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Calculator", action = "Index", id = UrlParameter.Optional }
);
}
}
}
