新的项目需要运行在WIN2003上,又不想用ASPX了,只好用回ASP.NET MVC4.0了,可是在VS2017中已经没有MVC4的模板了,网上下载的安装了也没有,只好把以前的MVC4的项目拿 出来看了一下,看看怎么由空白项目建立起来,步骤如下:
1.VS2017中建立空白的WEB项目,记得选择.NET 4.0版本的
2.NUGET包中搜索ASP.NET MVC,不要下5.0的那个版本,要下4.0的那个版本
3.自己手动建立Controllers文件夹,里面建立HomeController.cs类文件,文件内容
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Web.Http;
using System.Web.Mvc;
namespace WebApplication1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index() {
ViewBag.mes = "niunan hahaha ...";
return View(); }
}
}
4.自己手动建立Views文件夹,里面建立Home文件夹,里面建立Index.cshtml文件,文件内容:
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title></title>
</head>
<body>
<div>
这是MVC示例页
@ViewBag.mes
</div>
</body>
</html>
5.在Views文件夹下建立Web.config文件,内容:
<?xml version="1.0"?>
<configuration>
<configSections>
<sectionGroup name="system.web.webPages.razor"
type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup,
System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35">
<section name="host"
type="System.Web.WebPages.Razor.Configuration.HostSection,
System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
<section name="pages"
type="System.Web.WebPages.Razor.Configuration.RazorPagesSection,
System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>
</configSections>
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory,
System.Web.Mvc, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
</namespaces>
</pages>
</system.web.webPages.razor>
<appSettings>
<!--<add key="webpages:Enabled" value="false" />-->
<add key="webpages:Version" value="2.0.0.0" />
</appSettings>
<system.web>
<httpHandlers>
<add path="*" verb="*" type="System.Web.HttpNotFoundHandler"/>
</httpHandlers>
<!--
Enabling request validation in view pages would cause validation to occur
after the input has already been processed by the controller. By default
MVC performs request validation before a controller processes the input.
To change this behavior apply the ValidateInputAttribute to a
controller or action.
-->
<pages
validateRequest="false"
pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter,
System.Web.Mvc, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35"
pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc,
Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
userControlBaseType="System.Web.Mvc.ViewUserControl,
System.Web.Mvc, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35">
<controls>
<add assembly="System.Web.Mvc, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=31BF3856AD364E35"
namespace="System.Web.Mvc" tagPrefix="mvc" />
</controls>
</pages>
</system.web>
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<remove name="BlockViewHandler"/>
<add name="BlockViewHandler" path="*" verb="*"
preCondition="integratedMode" type="System.Web.HttpNotFoundHandler"
/>
</handlers>
</system.webServer>
</configuration>
感觉和默认的MVC5建立的出来的一样的,只是把版本号从5.0.0.0改为4.0.0.0了。。。
6.建立App_Start目录,里面建立FilterConfig.cs文件,内容:
using System.Web;
using System.Web.Mvc;
namespace WebApplication1
{
public class FilterConfig
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
}
}
感觉好像没有这个文件也不要紧
7.App_Start目录中建立RouteConfig.cs文件,内容:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
namespace WebApplication1
{
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
}
要用到MVC的,这个文件是最主要的话,用到MVC的路由创建
8.项目根目录下建立Global.asax文件,在Application_Start中注册一下上面建立的二个类,主要内容:
protected void Application_Start(object sender, EventArgs e)
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
9.运行项目,就可以看到界面出来了,不过好像在CSHTML中的智能提示是没有的,不知道怎么弄,先这样吧!!!
