如何从 Asp.net MVC 中的 bin 文件夹加载视图文件

Question

我在 asp.net mvc 项目上工作，我将一些视图文件传输到其他项目并为它们启用 "copy always"（复制到主项目的 bin 文件夹中）。

我创建了一个自定义视图引擎：

public class CMSViewEngine : WebFormViewEngine
    {
        public CMSViewEngine()
        {
            MasterLocationFormats = new string[]
            {
            "~/bin/Views/{1}/{0}.master",
            "~/bin/Views/Shared/{0}.master"
            };

            ViewLocationFormats = new string[]
            {
            "~/bin/Views/{1}/{0}.cshtml",
            "~/bin/Views/{1}/{0}.vbhtml",
            "~/bin/Views/Shared/{0}.cshtml",
            "~/bin/Views/Shared/{0}.vbhtml",
            "~/bin/Views/{1}/{0}.aspx",
            "~/bin/Views/{1}/{0}.ascx",
            "~/bin/Views/Shared/{0}.aspx",
            "~/bin/Views/Shared/{0}.ascx"
            };
        }
    }

然后添加到 global.ascx 中的 mvc ViewEngine

        ViewEngines.Engines.Add(new CMSViewEngine());

        AreaRegistration.RegisterAllAreas();
        RouteConfig.RegisterRoutes(RouteTable.Routes);

但我的问题是：显示视图时出现异常：

The view at '~/bin/Views/Forms/Index.cshtml' must derive from ViewPage, ViewPage, ViewUserControl, or ViewUserControl.

我尝试添加 web.config 来查看文件夹，也尝试添加 @inherits System.Web.Mvc.WebViewPage 来查看文件，但没有成功。

我的 web.config 用于 bin 视图文件的文件是：

<?xml version="1.0"?>

<configuration>
  <configSections>
    <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>
  </configSections>

  <system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, 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="TestProj.ContactFormApp" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>

  <appSettings>
    <add key="webpages:Enabled" value="false" />
  </appSettings>

  <system.webServer>
    <handlers>
      <remove name="BlockViewHandler"/>
      <add name="BlockViewHandler" path="*" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" />
    </handlers>
  </system.webServer>

  <system.web>
    <compilation>
      <assemblies>
        <add assembly="System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
      </assemblies>
    </compilation>
  </system.web>
</configuration>

如何解决加载视图文件的问题？

已解决：

我必须从 RazorViewEngine class（而不是 WebFormViewEngine）扩展 CMSViewEngine class 才能正常工作。

Answer 1

看起来您正在使用 WebFormViewEngine，如果是这种情况，您不应该在 WebFormViewEngine 中注册 razor 视图文件，您的 CMSViewEngine class 应该只包含基于 WebForm 的视图文件扩展名，例如：

public class CMSViewEngine : WebFormViewEngine
{
    public CMSViewEngine()
    {
        MasterLocationFormats = new string[]
        {
        "~/bin/Views/{1}/{0}.master",
        "~/bin/Views/Shared/{0}.master"
        };

        ViewLocationFormats = new string[]
        {
        "~/bin/Views/{1}/{0}.aspx",
        "~/bin/Views/{1}/{0}.ascx",
        "~/bin/Views/Shared/{0}.aspx",
        "~/bin/Views/Shared/{0}.ascx"
        };
    }
}

以防万一您使用 .NET Core 执行此操作，您可以将视图的路径放在 bin 文件夹中并传递您的模型。

 return View(@"bin\Debug\netcoreapp1.0\Views\Test.cshtml", new ReportLibrary.Person());
