ASP.NET MVC强类型部分视图,给出无法加载类型错误

Question

我正在尝试使用Html.RenderPartial()呈现带有"MVC View User Control"的强类型视图.我的ascx文件的顶部如下所示:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.Collections.IEnumerable<string>>" %>

目前,此页面上没有其他内容.

当我执行应用程序并加载呈现此控件的页面时,我收到以下错误:

 Could not load type 'System.Web.Mvc.ViewUserControl<System.Collections.IEnumerable<string>>'.

那么,我简化了它:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<String>" %>

然后,以防万一需要完全合格:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.String>" %>

每次我得到相同的错误(替换类型).我在这做错了什么？我在.NET 3.5上使用ASP.NET MVC 1.0 RTM.

Answer 1

我搞定了.我按照http://www.codewrecks.com/blog/index.php/2009/04/05/could-not-load-type-systemwebmvcviewpage/上的说明操作,这对我来说很有用.我应该注意到,我还是从2010年3月17日开始升级到ASP.NET MVC 2.0 RC.在我按照该页面上的说明操作之前,问题仍然存在.我不确定一个新的MVC项目现在是否适合你.

如果引用的页面消失,解决方案是将Web.config添加到我的Views目录,并将其放入其中:

<?xml version="1.0"?>
<configuration>
  <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=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
    pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
    userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
  <controls>
    <add assembly="System.Web.Mvc, Version=2.0.0.0, 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>

我还要注意,对于MVC 2.0,您需要更新配置中的版本#.
