ASP.NET 如何使用 OWIN 注册自定义视图引擎

Question

我正在尝试实现自定义视图引擎，它可以让我指定额外的视图路径，如下所示：

public class CustomViewEngine : RazorViewEngine
{
    public CustomViewEngine()
    {
        ViewLocationFormats = new[]
        {
            "~/Views/{1}/{0}.cshtml", "~/Views/{1}/{0}.vbhtml",
            "~/Views/Shared/{0}.cshtml", "~/Views/Shared/{0}.vbhtml"
        };
        MasterLocationFormats = new[]
            {
            "~/Views/{1}/{0}.cshtml", "~/Views/{1}/{0}.vbhtml",
            "~/Views/Shared/{0}.cshtml", "~/Views/Shared/{0}.vbhtml"
        };
        PartialViewLocationFormats = new[]
            {
            "~/Views/{1}/{0}.cshtml", "~/Views/{1}/{0}.vbhtml",
            "~/Views/Shared/{0}.cshtml", "~/Views/Shared/{0}.vbhtml",
            "~/Views/Partials/Widgets/{0}.cshtml", "~/Views/Partials/Widgets/{0}.vbhtml"
        };

    }
}

Global.asax.cs 中有很多如何使用它的源代码，例如：Can I specify a custom location to "search for views" in ASP.NET MVC? 但是没有任何来源可以说明在使用 OWIN 时如何注册此引擎。怎么做？

试试这个：

Startup.cs

using System.Web.Mvc;
using Microsoft.Owin;
using Owin;

[assembly: OwinStartup(typeof(WebApplication2.Startup))]

namespace WebApplication2
{
   public class Startup
   {
      public void Configuration(IAppBuilder app)
      {
         ViewEngines.Engines.Clear();
         ViewEngines.Engines.Add(new CustomViewEngine());
      }
   }
}
