我可以指定一个自定义位置来“搜索视图"吗?在 ASP.NET MVC 中? [英] Can I specify a custom location to "search for views" in ASP.NET MVC?

问题描述

我的 mvc 项目具有以下布局:

I have the following layout for my mvc project:

• /控制器
  • /演示
  • /Demo/DemoArea1Controller
  • /Demo/DemoArea2Controller
  • 等等...
  • /演示
  • /Demo/DemoArea1/Index.aspx
  • /Demo/DemoArea2/Index.aspx

  但是，当我为 DemoArea1Controller 设置这个时:

  However, when I have this for DemoArea1Controller:

  public class DemoArea1Controller : Controller
  {
      public ActionResult Index()
      {
          return View();
      }
  }
  

  我收到无法找到视图‘索引’或其主视图"错误，以及通常的搜索位置.

  I get the "The view 'index' or its master could not be found" error, with the usual search locations.

  如何在Demo"视图子文件夹中的Demo"命名空间搜索中指定控制器?

  How can I specify that controllers in the "Demo" namespace search in the "Demo" view subfolder?

  推荐答案

  您可以轻松扩展 WebFormViewEngine 以指定要查找的所有位置:

  You can easily extend the WebFormViewEngine to specify all the locations you want to look in:

  public class CustomViewEngine : WebFormViewEngine
  {
      public CustomViewEngine()
      {
          var viewLocations =  new[] {  
              "~/Views/{1}/{0}.aspx",  
              "~/Views/{1}/{0}.ascx",  
              "~/Views/Shared/{0}.aspx",  
              "~/Views/Shared/{0}.ascx",  
              "~/AnotherPath/Views/{0}.ascx"
              // etc
          };
  
          this.PartialViewLocationFormats = viewLocations;
          this.ViewLocationFormats = viewLocations;
      }
  }
  

  确保您记得通过修改 Global.asax.cs 中的 Application_Start 方法来注册视图引擎

  Make sure you remember to register the view engine by modifying the Application_Start method in your Global.asax.cs

  protected void Application_Start()
  {
      ViewEngines.Engines.Clear();
      ViewEngines.Engines.Add(new CustomViewEngine());
  }
