ASP.NET MVC - 找不到区域内的 WEB API

如何解决ASP.NET MVC - 找不到区域内的 WEB API

我有 1 个包含 API 的区域，但我无法调用它，也不明白为什么，这里是代码：

不在区域：WebApiConfig

public static void Register(HttpConfiguration config)
{
    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
                name: "DefaultApi",routeTemplate: "api/{controller}/{action}/{id}",defaults: new { id = RouteParameter.Optional }
            );
    config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html")); //per convertire in .json
}

Global.asax：

protected void Application_Start()
{
     AreaRegistration.RegisterallAreas();
     FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
     RouteConfig.RegisterRoutes(RouteTable.Routes);
     BundleConfig.RegisterBundles(BundleTable.Bundles);
}

然后在区域里面有一个名为 Tyre24AreaRegistration 的文件：

public class Tyre24AreaRegistration : AreaRegistration 
{
        public override string AreaName 
        {
            get 
            {
                return "Tyre24";
            }
        }

        public override void Registerarea(AreaRegistrationContext context) 
        {
            context.MapRoute(
            "Download","Tyre24/api/{controller}/{action}/{id}",new {controller = "Download",id = UrlParameter.Optional }
             ); //not working < 
            context.MapRoute(
                "Tyre24_default","Tyre24/{controller}/{action}/{id}",new { action = "Index",id = UrlParameter.Optional }
            );
        }
}

查看：

<div> @Html.ActionLink("DownloadExportTyres","DownloadExportTyres","Download",new { area = "Tyre24" },null)</div>

控制器：

public class DownloadController : ApiController
    {
        [HttpGet]        
        public IHttpActionResult DownloadExportTyres()
        {
          ......
        }
    }

我实际上尝试了许多在 stackoverflow 中的“解决方案”，但在这种情况下没有任何帮助
