返璞归真asp.net mvc 1.0(5) - Action Filter, UpdateModel, ModelBinder, Ajax, Unit Test【转】

介绍
asp.net mvc 之 Action Filter, UpdateModel, ModelBinder, Ajax, Unit Test

Action Filter - 在 Controller 层对信息做过滤。如何实现自定义的 Action Filter
UpdateModel - 根据参数自动为对象的属性赋值
ModelBinder - 定义如何绑定 Model，DefaultModelBinder 实现了 IModelBinder ，其可以根据名称自动将参数赋值到对象对应的属性上
Ajax - 在 asp.net mvc 中使用 ajax
Unit Test - 在 asp.net mvc 中使用单元测试

示例
1、asp.net mvc 自带的 Action Filter 的演示
FilterDemoController.cs

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

using MVC.Models;

namespace MVC.Controllers

自定的 Action Filter 的实现
MyFilter.cs

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

using System.Web.Mvc;

namespace MVC

Details.aspx

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Details
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<%= Html.AntiForgeryToken() %>
<h2>
Details</h2>
<p>
<strong>ProductID:</strong>
<%= Html.Encode(Model.ProductID) %>
</p>
<p>
<strong>ProductName:</strong>
<%= Html.Encode(Model.ProductName) %>
</p>
<p>
<input type="submit" name="btnSubmit" value="submit" />
</p>
</asp:Content>

2、应用 UpdateModel 的 Demo
UpdateModelController.cs

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

namespace MVC.Controllers

Details.aspx

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Details
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>
Details</h2>
<p>
<strong>UserId:</strong>
<%= Model.ID %>
</p>
<p>
<strong>Name:</strong>
<%= Model.Name%>
</p>
<p>
<strong>Age:</strong>
<%= Model.Age%>
</p>
</asp:Content>

3、演示什么是 ModelBinder
ModelBinderController.cs

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

namespace MVC.Controllers

Details.aspx

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Details
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>
Details</h2>
<p>
<strong>UserId:</strong>
<%= model.ID %>
</p>
<p>
<strong>Name:</strong>
<%= model.Name %>
</p>
<p>
<strong>Age:</strong>
<%= model.Age %>
</p>
<p>
<strong>error:</strong>
<%= ViewData["errorMsg"] %>
</p>
</asp:Content>

4、使用 ajax 的 Demo

<p>
Ajax

<script src="http://www.cnblogs.com/Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="http://www.cnblogs.com/Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>

<br />

<!-- AjaxHelper 简要说明 -->
<%= Ajax.ActionLink(
"ProductId 为 1 的详情页",
"Details",
"Product",
new { id = 1 },
new AjaxOptions { UpdateTargetId = "ajax" }
)
%>
</p>
<div id="ajax" />

5、在 VS 中做单元测试
ProductControllerTest.cs

using MVC.Controllers;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Microsoft.VisualStudio.TestTools.UnitTesting.Web;
using System.Web.Mvc;

using MVC.Models;
using System.Collections.Generic;

namespace MVC.Tests
