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 id="colors">

@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 id="colors_a">

@foreach (var color in @ViewBag.ListColors)

{

<li>

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

</li>

}

<li></li>

</ul>

</div>
