ASP.NET MVC3数据绑定到VIEW的方式

1、     指定页面数据的强类型Module

数据类型是强类型，编译时报错，运行效率高

Action:

      public ActionResult Index()

      {

        var _instructors = new List<Instructor>(

           new Instructor[]

           {

              new Instructor

              {

                 Name = "Nimane1",

                 TwitterHandler = "@fasdd",

                 HtmlDescription = "This"

              }

              , new Instructor

              {

                 Name = "Nimane2",

                 TwitterHandler = "@fasdd",

                 HtmlDescription = "This"

              }

           }

        );

        ViewBag.Message = "Welcome to ASP.NET MVC!";

        return this.View(_instructors);

      }

View:

@using MvcApplication1.Models

@model IEnumerable<Instructor>

@{

    ViewBag.Title = "Index";

    Layout = "~/Views/Shared/_Layout.cshtml";

}

<h2>@ViewBag.Message</h2>

<div>

    @foreach (var item in Model)

    {

        @Html.Partial("InstructorView", item)

    }

</div>

InstructorView:

@model MvcApplication1.Models.Instructor

<fieldset>

    <legend>Instructor</legend>

    <div class="display-label">

        Name</div>

    <div class="display-field">

        @Model.Name

    </div>

    <div class="display-label">

        TwitterHandler</div>

    <div class="display-field">

        @Model.TwitterHandler

    </div>

    <div class="display-label">

        HtmlDescription</div>

    <div class="display-field">

        @Html.Raw(@Model.HtmlDescription)</div>

</fieldset>

<p>

    @Html.ActionLink("Edit", "Edit", new { })

    @Html.ActionLink("Back to list", "Index")

</p>

2、     使用ViewData绑定到页面

数据类型是object，运行时报错，在 页面中需要对数据进行显示转换，运行效率低

Action：

      public ActionResult ViewData ()

      {

        List<string> colors = new List<string>(

           new string[]

           {

              "red","green","blue"

           }

        );

        ViewData["listColors"] = colors;

        ViewData["dateNow"] = DateTime.Now;

        ViewData["name"] = "Nicoles";

        ViewData["age"] = 24;

        return this.View();

      }

View：

    <div>

        <p>section for viewdata display:</p>

        <p>my name is :

            <b>@ViewData["name"]</b>

            <b>@ViewData["age"]</b> years old.

            <br/>

            I like the colors:

        </p>

        <ul >

            @foreach (var color in ViewData["listColors"] as List<string>)

            {

                <li>

                    <font color="@color">@color</font>

                </li>

            }

            <li></li>

        </ul>

    </div>

3、     使用ViewBag绑定到页面

数据类型是dynamic，运行时报错，运行效率中

      public ActionResult ViewBag()

      {

        List<string> colors = new List<string>(

           new string[]

           {

              "red","green","blue"

           }

        );

        ViewBag.ListColors = colors;

        ViewBag.DateNow = DateTime.Now;

        ViewBag.Name = "Nicoles";

        ViewBag.Age = 24;

        return this.View();

      }

View:

<div>

        <p>section for viewbag display:</p>

        <p>my name is :

            <b>@ViewBag.Name</b>

            <b>@ViewBag.Age</b> years old.

            <br/>

            I like the colors:

        </p>

        <ul >

            @foreach (var color in @ViewBag.ListColors)

            {

                <li>

                    <font color="@color">@color</font>

                </li>

            }

            <li></li>

        </ul>

    </div>
