1.编写控制器
三个步骤：
【1】获取数据
【2】业务处理
【3】返回数据
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MvcLoginDemo.Models;
namespace MvcLoginDemo.Controllers
{
???public class SysAdminController : Controller
???{
???????//
???????// GET: /SysAdmin/
???????public ActionResult Index()
???????{
???????????return View("AdminLogin");
???????}
???????/// <summary>
???????/// 用户登录控制器
???????/// </summary>
???????/// <returns></returns>
???????public ?ActionResult AdminLogin()
???????{
??????????//【1】获取数据 ??????????
???????????SysAdmin objAdmin = new SysAdmin()
???????????{
???????????????LoginId = Convert.ToInt32(Request.Params["loginId"]),
???????????????LoginPwd = Request.Params["loginPwd"]
???????????};
?????????//【2】业务处理
???????????new SysAdminService().AdminLogin(objAdmin);
???????????if(objAdmin!=null)
???????????{
???????????????ViewData["info"] = "欢迎您：" + objAdmin.AdminName;
???????????}
???????????else
???????????{
???????????????ViewData["info"] = "用户名或密码错误";
???????????}
?????????//【3】返回数据
???????????return View();
???????} ?????
???}
}
2.最后编写视图层
asp.net -mvc框架复习（9）-实现用户登录控制器和视图的编写并调试
