Ext.NET未與ASP.NET MVC集成4

Question

我在VS 2012中創建了MVC 4 Web應用程序。 通過NuGet下載了Ext.Net 2。 在我看來的/ home/index.cshtml文件，我想鍵入：

@Html.X().ResourceManager() 

我正在以下，當我運行：

CS1061：「System.Web.Mvc.HtmlHelper '不包含'X'的定義，並且沒有找到接受'System.Web.Mvc.HtmlHelper'類型的第一個參數的擴展方法'X'（您是否缺少使用指令或程序集引用？）

這是我的web.config

Answer 1

您能否確認您在項目中添加了適當的Ext.Net.dll引用？

編輯：我相信你的<runtime>節點裏面的<system.webserver>是不正確的。應該是以下內容，其中每個大會定義爲單獨的<assemblyBinding>。

<runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
     <dependentAssembly> 
      <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" /> 
      <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" /> 
     </dependentAssembly> 
     <dependentAssembly> 
      <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" /> 
      <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.5.7" /> 
     </dependentAssembly> 
     <dependentAssembly> 
      <assemblyIdentity name="Ext.Net.Utilities" publicKeyToken="2c34ac34702a3c23" /> 
      <bindingRedirect oldVersion="0.0.0.0-2.0.0" newVersion="2.0.1" /> 
     </dependentAssembly> 
     <dependentAssembly> 
      <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> 
      <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" /> 
     </dependentAssembly> 
     <dependentAssembly> 
      <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" /> 
      <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" /> 
     </dependentAssembly> 
    </assemblyBinding> 
</runtime> 

我相信NuGet可能存在缺陷。我們已經看到NuGet在<dependentAssembly>上添加這些彙編配置的其他報告。

如果您對<runtime>進行上述更改，您的項目應該可以正常工作。

1. 在<system.web>

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

2. 正確assemblyBinding在geoffrey.mcgill文章添加Ext.Net到組件中<system.web>

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

3. 添加命名空間像

4. 添加命名空間在web.config中n個視點文件夾（在<system.web.webPages.razor>節）

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

5. 在web.config中添加Ext.Net裝配在瀏覽文件夾（在<system.web>節）

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

Answer 3

請不要使用的NuGet獲得Ext.Net DLL。我相信Ext.Net團隊不會更新Nuget ASAP中的Ext.Net DLL。因爲我發現版本是Nuget 2.1.1.11828，它沒有Ext.Net.Mvc命名空間。但是最新發布版本是2.1.1.18233，它有Ext.Net.Mvc命名空間...
