asp.net-mvc - Ext.NET 未与 ASP.NET MVC 4 集成

Question

我在 VS 2012 中创建了一个 MVC 4 Web 应用程序。
通过 NuGet 下载 Ext.Net 2。
在我的 view/home/index.cshtml 文件中，我尝试输入:

@Html.X().ResourceManager()

当我运行时，我得到以下信息:

CS1061: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'X' and no extension method 'X' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)

这是我的 web.config

Answer 1

将 Ext.Net 添加到 <system.web> 中的程序集

 <compilation debug="true" targetFramework="4.0">
      <assemblies>
        ....
          <add assembly="Ext.Net"/>
      </assemblies>
 </compilation>

在 <system.web> 中添加命名空间

<pages>
  <namespaces>
     ....
    <add namespace="Ext.Net"/>
    <add namespace="Ext.Net.MVC"/>
  </namespaces>
</pages>

像 geoffrey.mcgill 帖子

中的正确组装绑定(bind)

在 Views 文件夹的 web.config 中添加命名空间(在 <system.web.webPages.razor> 部分)

<pages pageBaseType="System.Web.Mvc.WebViewPage">
    <namespaces>
       ....
       <add namespace="Ext.Net" />
       <add namespace="Ext.Net.MVC" />
    </namespaces>
 </pages>

在 Views 文件夹的 web.config 中添加 Ext.Net 程序集(在 <system.web> 部分)

 <pages ....>
    <controls>
        ....
       <add assembly="Ext.Net" namespace="Ext.Net" tagPrefix="ext" />
    </controls>
 </pages>
