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

OK
