AspNet MVC4 教学-25:Asp.Net MVC4 强弱类型View等技术高速对照Demo

Posted 2020-09-24

A.创建Basic类型项目.

B.Model文件夹下创建4个类文件:

Teacher.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MvcViewModelTest.Models
{
    public class Teacher
    {
        public string Name
        {
            get
            {
                return "马老师";
            }
        }
        public string Remark
        {
            get
            {
                return "计算机教师";
            }
        }
    }
}

Student.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MvcViewModelTest.Models
{
    public class Student
    {
        public string Name
        {
            get
            {
                return "张三";
            }
        }
        public string Remark
        {
            get
            {
                return "电商学生";
            }
        }
    }

AllPersons.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MvcViewModelTest.Models
{
    public class AllPersons
    {
        public Teacher tea=new Teacher();
        public Student stu=new Student();       
      
    }
}

Other.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MvcViewModelTest.Models
{
    public class Other
    {
        public string Name
        {
            get
            {
                return "李四";
            }
        }
        public string Remark
        {
            get
            {
                return "后勤人员";
            }
        }
    }
}


}

C.创建HomeController.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MvcViewModelTest.Models;

namespace MvcViewModelTest.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/

        public ActionResult Index()
        {
            ViewBag.Other = new Other();
            return View(new AllPersons());
        }
   
    }
}

D.View/Home/创建1个文件:

Index.cshtml:

@using MvcViewModelTest.Models
@model AllPersons
@{
    ViewBag.Title = "Index";
    
}
<h2>
    Index</h2>
<fieldset>
    <legend>Teacher-利用Model编辑时有智能感应</legend>
    <h2>@Model.tea.Name</h2>
    <h2>@Model.tea.Remark</h2>
</fieldset>
<fieldset>
    <legend>Teacher-利用DisplayFor编辑时有智能感应</legend>
    <h2>@Html.DisplayFor(m => m.tea.Name)</h2>
    <h2>@Html.DisplayFor(m => m.tea.Remark)</h2>
</fieldset>
<fieldset>
    <legend>Teacher-TextBox的4种显示技术</legend>

    <h2>HTML: <input id="tea_Name" name="tea.Name" type="text" value="马老师" /></h2>
    <h2>TextBox: @Html.TextBox("tea.Name", Model.tea.Name)</h2>
    <h2>TextBoxFor: @Html.TextBoxFor(m => m.tea.Name)</h2>
    <h2>EditorFor: @Html.EditorFor(m => m.tea.Name)</h2>
</fieldset>
<fieldset>
    <legend>Student-利用Model编辑时有智能感应</legend>
    <h2>@Model.stu.Name</h2>
    <h2>@Model.stu.Remark</h2>
</fieldset>
<fieldset>
    <legend>Student-利用DisplayFor编辑时有智能感应</legend>
    <h2>@Html.DisplayFor(m => m.stu.Name)</h2>
    <h2>@Html.DisplayFor(m => m.stu.Remark)</h2>
</fieldset>
<fieldset>
    <legend>Other-编辑时没有智能感应</legend>
    <h2>@ViewBag.Other.Name</h2>
    <h2>@ViewBag.Other.Remark</h2>
</fieldset>
@{    
    var ot = ViewBag.Other as Other;    
}
<fieldset>
    <legend>Other-编辑时有智能感应</legend>
    <h2>@ot.Name</h2>
    <h2>@ot.Remark</h2>
</fieldset>
