“System.Web.WebPages.Html.HtmlHelper'不包含'ActionLink的定义

本文介绍了“System.Web.WebPages.Html.HtmlHelper'不包含'ActionLink的定义的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

首先 - 我已经走遍SO 并发现有很多问题问同样的事情，虽然简单地添加＆LT;添加命名空间=System.Web.Mvc.Html/＆GT ; 在我的web.config没治好这个问题...

好了，我已经开始了一个新的项目，基于模板的角SPA - 链接是在这里：

http://visualstudiogallery.msdn.microsoft.com/5af151b2-9ed2-4809-bfe8-27566bfe7d83

我已经升级了MVC 5版＆安培;在的WebAPI到版本2 - 下跌与溶液中的其他项目行

现在，在SPA网站我试图使用 @ Html.ActionLink 帮手_layout页面，虽然不断收到错误 System.Web.WebPages.Html.HtmlHelper'不包含定义'ActionLink的

我相信这是所有到一些web.config配置 - 某种冲突的什么包我已经安装了，哪些是从模板的配置设置。

。

在具体地，该部分：

 ＆LT; system.web.webPages.razor＆GT;
    ＆LT;主机factoryType =System.Web.WebPages.Razor.WebRazorHostFactory，System.Web.WebPages.Razor，版本= 3.0.0.0，文化=中性公钥= 31BF3856AD364E35/＆GT;
    ＆LT;页面pageBaseType =System.Web.WebPages.WebPage＆GT;
      ＆LT;＆命名空间GT;
        ＆LT;添加命名空间=System.Web.Helpers/＆GT;
        ＆LT;添加命名空间=System.Web.Mvc/＆GT;
        ＆LT;添加命名空间=System.Web.Mvc.Ajax/＆GT;
        ＆LT;添加命名空间=System.Web.Mvc.Html/＆GT;
        ＆LT;添加命名空间=System.Web.Optimization/＆GT;
        ＆LT;添加命名空间=System.Web.Routing/＆GT;
        ＆LT;添加命名空间=System.Web.WebPages/＆GT;
      ＆LT; /命名空间＆GT;
    ＆LT; /页＆GT;
  ＆LT; /system.web.webPages.razor>

如果我改变了用5版本，那么我得到错误的组件（V5）无法定位等。

我运行了关于如何解决这个矛盾的想法。

下面是从我的SPA web.config中配置部分

 ＆LT; sectionGroup NAME =system.web.webPages.razorTYPE =System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup，System.Web.WebPages.Razor，版本= 3.0.0.0，文化=中性公钥= 31BF3856AD364E35＆GT;
      ＆lt;节名称=主机TYPE =System.Web.WebPages.Razor.Configuration.HostSection，System.Web.WebPages.Razor，版本= 3.0.0.0，文化=中性公钥= 31BF3856AD364E35requirePermission =假 /＆GT;
      ＆lt;节名称=页面TYPE =System.Web.WebPages.Razor.Configuration.RazorPagesSection，System.Web.WebPages.Razor，版本= 3.0.0.0，文化=中性公钥= 31BF3856AD364E35requirePermission =假 /＆GT;
    ＆LT; / sectionGroup＆GT;

如果我更改版本5，我得到以下错误：

解决方案

我与VS 2013的工作临更新2.这是我工作：


  1. 关闭Visual Studio中

  2. 删除bin和OBJ文件夹

  3. 重新打开您的解决方案，重建

  4. 在视图中没有更多的错误

BTW，没有必要改变对配置文件什么，简单的清洁和重建的解决方案是行不通的。

Firstly - I have scoured SO and found many questions asking the same thing, though simply adding <add namespace="System.Web.Mvc.Html" /> in my web.config didn't cure the issue...

Ok, so I have started a new project, based on the template Angular SPA - link is here:

http://visualstudiogallery.msdn.microsoft.com/5af151b2-9ed2-4809-bfe8-27566bfe7d83

I have upgraded the MVC to version 5 & the webApi to version 2 - to fall in line with other projects in the solution.

Now, in the _layout page of the SPA site I am trying to use the @Html.ActionLink helper, though keep getting the error 'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'ActionLink

I am sure this is all down to some web.config configuration - some kind of conflict between what packages I have installed and what is setup in the config from the template.

In particular, this part:

<system.web.webPages.razor>
    <host factoryType="System.Web.WebPages.Razor.WebRazorHostFactory, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <pages pageBaseType="System.Web.WebPages.WebPage">
      <namespaces>
        <add namespace="System.Web.Helpers" />
        <add namespace="System.Web.Mvc" />
        <add namespace="System.Web.Mvc.Ajax" />
        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Optimization" />
        <add namespace="System.Web.Routing" />
        <add namespace="System.Web.WebPages" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>

If I change this to use version 5 then I get the error that the assembly (v5) could not be located etc.

I am running out of ideas on how to resolve this conflict.

Here are the config sections from my SPA web.config

<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
      <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
      <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    </sectionGroup>

If I change the version to 5, I get the error below:

解决方案

I'm working with VS 2013 Pro Update 2. This is what worked for me:

  1. Close Visual Studio
  2. Delete bin and obj folders
  3. Reopen your solution and rebuild
  4. No more errors on the view

BTW there is no need to change anything on configuration files and a simple clean and rebuild solution does not work.
