Model 添加了一个UserInfo类 UserInfo.cs

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace MvcApplication1.Models{    public class UserInfo    {        public string Name { get; set; }        public int Age { get; set; }        public string Gender { get;set; }    }}

控制器 HomeController.cs

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using MvcApplication1.Models;namespace MvcApplication1.Controllers{    public class HomeController : Controller    {        //        // GET: /Home/        public ActionResult Index()        {            return View();        }        public ActionResult UserInfo()        {            List<UserInfo> userinfo = new List<UserInfo>()            {                new UserInfo(){ Name="小w王", Age=18, Gender="女"},                new UserInfo(){ Name = "小李", Age = 19, Gender = "男"}             };            ViewData["userinfo"] = userinfo;            return View();        }    }}

视图：UserInfo.aspx

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %><!--这里是引入UserInfo类所在的的MvcApplication1.Models名称空间--><%@ Import Namespace="MvcApplication1.Models" %><!DOCTYPE html><html><head runat="server">    <meta name="viewport" content="width=device-width" />    <title>UserInfo</title></head><body>    <div>          <table>        <tr><th>姓名</th><th>年龄</th><th>性别</th></tr>      <% List<UserInfo> userinfo = ViewData["UserInfo"] as List<UserInfo>;             foreach(var v in userinfo)             { %>                <tr><td><%:v.Name %> </td><td><%:v.Age %></td><td><%:v.Gender %></td></tr>                            <% }  %>                                  </table>      </div></body></html>

Model 添加了一个UserInfo类 UserInfo.cs

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace MvcApplication1.Models{    public class UserInfo    {        public string Name { get; set; }        public int Age { get; set; }        public string Gender { get;set; }    }}

控制器 HomeController.cs

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using MvcApplication1.Models;namespace MvcApplication1.Controllers{    public class HomeController : Controller    {        //        // GET: /Home/        public ActionResult Index()        {            List<UserInfo> userInfo = new List<UserInfo>(){                new UserInfo(){Name="小鸭子", Age=26, Gender="女"},                new UserInfo(){Name="二狗子", Age=18, Gender="男"},                new UserInfo(){Name="小鱼儿", Age=22, Gender="女"}            };            ViewData.Model = userInfo;            return View();        }        }}

视图 Index.aspx

注意下面的两行非常重要

<!--注意该页面继承了IEnumerable<MvcApplication1.Models.UserInfo>--><%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<IEnumerable<MvcApplication1.Models.UserInfo>>" %><!DOCTYPE html><html><head runat="server">    <meta name="viewport" content="width=device-width" />    <title>这是强类型页面</title></head><body>    <div>               <table>        <tr><th>姓名</th><th>年龄</th><th>性别</th></tr>        <!--ViewData是ViewPage<TModel>泛型类的一个ViewDataDictionary类型的属性；而同时ViewData又是ViewDataDictionary类的一个对象，而ViewDataDictionary类下面又定义了Model属性，所以ViewData可以点Model。在Home控制器的Index方法里用它(ViewData.Model)来接收了一个list对象。所以这里我们就遍历这个Model-->        <% foreach(var v in Model){%>                                      <tr><td><%:v.Name %></td><td><%:v.Age %></td><td><%:v.Gender %></td></tr>                <%} %>       </table>          </div></body></html>
