HttpCompileException，CS024名称空间找不到

Question

运行我的项目时，出现“用户代码未处理HttpCompileException”消息。我已经查看了所有与这个问题类似的网站问题，但是没有一个解决方案能够工作。

我曾尝试：

• 重新启动我的电脑。
• 改变了大会类型的.NET Framework 4我所有的项目
• 我重塑了我的项目

时运行它，它用一个错误的代码返回：CS0246。

全部查看经销商代码C＃ASP.NET MVC3。我有一个局部的看法，我试图从我的服务层传递信息。它嵌套在我的共享布局部分中，以提供我的网站结构。我新了一个对象，我打电话给我的部分：

@Html.Partial("Profile", new UserService()) 

好，误差不抛出这个代码，但祖父母类的地方，这是coded.I认为我需要添加我的using语句中的所有父母当前部分的部分。这不起作用，但抛出相同的错误，除了我放置使用语句的位置。

我花了很多时间处理这个错误。在我看来，这不是我问题的答案。任何其他想法或建议？

似乎你的剃刀视图对你尝试使用的类UserService一无所知。请确保您已经添加在这个类是在你的视图的顶部定义的命名空间：

@using AppName.Models 
... 
@Html.Partial("Profile", new UserService()) 

或完全限定它：

@Html.Partial("Profile", new AppName.Models.UserService()) 

或将其添加到您的~/Views/web.config文件的<namespaces>节（推荐为现在这个类型将提供给所有剃刀视图）：

<system.web.webPages.razor> 
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, 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" /> 
      <add namespace="AppName.Models" /> 
     </namespaces> 
    </pages> 
</system.web.webPages.razor>

既然您已通过邮件向我发送了VS2010解决方案，我明白您的问题所在。您的Rizowski.Services和Data.Rizowski项目都是控制台应用程序。你应该将它们转换为类库。右键点击他们每个人，并在属性改变输出方式Class Library：
