C# 关于MVC框架的简单实例（计算器）
一、需求分析
實(shí)現(xiàn)效果
?
二、實(shí)現(xiàn)步驟
?
步驟一：新建項(xiàng)目--->Web---->空模板
?
步驟二：添加控制器
步驟三：根據(jù)控制器名稱(chēng)添加視圖
步驟四：添加Models模型? 編寫(xiě)具體的方法
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;
??????? }
??? }
}
步驟五：編寫(xiě)視圖，具體展示的內(nèi)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">
??????? 計(jì)算平均成績(jī)<br/>
??????? 總成績(jī)：<input type="text" name="sumScore" /> <br/>
??????? 總科目：<input type="text" name="sumSubject" /><br/>
??????? <input type="submit"? value="開(kāi)始計(jì)算"/><br/>
??????? @ViewData["avgScore"] ?
??? </form>
? ?
</body>
</html>
步驟六：編寫(xiě)控制器活動(dòng)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]獲取數(shù)據(jù)
??????????? int sumScore = Convert.ToInt32(Request.Params["sumScore"]);
??????????? int sumSubject = Convert.ToInt32(Request.Params["sumSubject"]);
??????????? //[2]處理數(shù)據(jù)
??????????? Calculator objCal = new Calculator();
??????????? int avgScore = objCal.getAVG(sumScore, sumSubject);
??????????? //[3]返回?cái)?shù)據(jù)
??????????? ViewData["avgScore"] = "平均成績(jī)?yōu)?#xff1a;" + avgScore;
??????????? return View("CalculatorView");
??????? }
??? }
}
步驟七：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 }
??????????? );
??????? }
??? }
}
