ASP.NET MVC4不会在不同的程序集中加载视图

标签： asp.net view .net-assembly

我需要将不同的项目区域分成单独的组合......我在解决视图方面遇到了问题。 我有一个主要项目，它是一个带有razor和StructureMap for IoC的mvc4项目，我创建了另一个MVC4项目，我删除了配置文件和App_Start foler ...在Controllers文件夹下创建了一个名为AdminController的测试类，在Views \ Admin下一个名为Index.cshtml的文件......

AdminController.cs：

public class AdminController : Controller
{
    //
    // GET: /Admin/

    public ActionResult Index()
    {
        return View();
    }
[...omiss...]
}

Index.cshtml：

@{
ViewBag.Title = "Index";
}

<h2>Index</h2>
That's the admin view

我的Global.asax：

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RouteConfig.RegisterRoutes(RouteTable.Routes);

        //WebApiConfig.Register(GlobalConfiguration.Configuration);
        //FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);


        WireUpDependencyInjection();
        ControllerBuilder.Current.SetControllerFactory(new ControllerFactory());
    }

    private void WireUpDependencyInjection()
    {

        ObjectFactory.Initialize(registry => registry.Scan(x =>
        {
            x.AssembliesFromApplicationBaseDirectory();
            x.WithDefaultConventions();
        }));
    }
}

当我去/ Admin我有

我不想将视图放在主项目中...以获得可伸缩性...我希望将它们保留在程序集中，或者更好地保存在另一个程序集中（可能使用RazorGenerator）

任何人都可以帮助我完成加载视图的第一步吗？ 感谢

答案 0 :(得分：1)

除非在Visual Studio中将每个视图文件的“构建操作”设置为“嵌入式资源”，否则您的视图不会在程序集中结束（右键单击该文件，选择属性）。但是运行时仍然无法找到视图，因为默认行为是在磁盘上查找视图，而不是在程序集内查找视图。但是这种行为可以改变。

因此，如果你真的开始在程序集中嵌入视图，那么你必须实现VirtualPathProvider并在主应用程序启动时注册它。所有提供者都有机会提供“虚拟文件”，因此您的提供者将有机会将视图文件流出程序集（如果运行时请求视图）。

另一种方法是在二级项目中添加一个post build事件，它只是将Views文件夹中的所有内容复制到主项目中。在这种情况下，我建议您使用MVC areas，以防止复制文件时发生任何冲突。这意味着您不必记住嵌入视图文件，也不必编写虚拟路径提供程序。

使用可以使用RazorGenerator以便在不同的程序集中拥有（预编译的）视图。请查看Usage in a View Library以了解具体方法。

基本上，诀窍就是消耗RazorGenerator.Mvc NuGet，它会注册一个视图引擎，并为你做一些VirtualPathProvider。
