asp.net-mvc - T4MVC 和不同区域的重复 Controller 名称

Question

在我的应用程序中，我有一个名为 Snippets 的 Controller 在默认区域(在应用程序根目录中)和我的区域中都称为 Manage .我使用 T4MVC 和自定义路由，如下所示:

routes.MapRoute(
    "Feed",
    "feed/",
    MVC.Snippets.Rss()
);

我得到这个错误:

Multiple types were found that match the controller named 'snippets'. This can happen if the route that services this request ('{controller}/{action}/{id}/') does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter.

The request for 'snippets' has found the following matching controllers: Snippets.Controllers.SnippetsController Snippets.Areas.Manage.Controllers.SnippetsController

我知道 MapRoute 存在过载需要namespaces论点，但 T4MVC 支持没有这样的重载。可能是我错过了什么？可能的语法可以是:

routes.MapRoute(
    "Feed",
    "feed/",
    MVC.Snippets.Rss(),
    new string[] {"Snippets.Controllers"}           
);

或者，将命名空间作为 T4MVC 属性对我来说似乎很好:

routes.MapRoute(
    "Feed",
    "feed/",
    MVC.Snippets.Rss(),
    new string[] {MVC.Snippets.Namespace}           
);

提前致谢!

说得通。我猜你只是第一个遇到这种情况的人。尝试将 T4MVC.tt 中的所有 MapRoute 方法替换为以下内容:

    public static Route MapRoute(this RouteCollection routes, string name, string url, ActionResult result) {
        return MapRoute(routes, name, url, result, null /*namespaces*/);
    }

    public static Route MapRoute(this RouteCollection routes, string name, string url, ActionResult result, object defaults) {
        return MapRoute(routes, name, url, result, defaults, null /*constraints*/, null /*namespaces*/);
    }

    public static Route MapRoute(this RouteCollection routes, string name, string url, ActionResult result, string[] namespaces) {
        return MapRoute(routes, name, url, result, null /*defaults*/, namespaces);
    }

    public static Route MapRoute(this RouteCollection routes, string name, string url, ActionResult result, object defaults, object constraints) {
        return MapRoute(routes, name, url, result, defaults, constraints, null /*namespaces*/);
    }

    public static Route MapRoute(this RouteCollection routes, string name, string url, ActionResult result, object defaults, string[] namespaces) {
        return MapRoute(routes, name, url, result, defaults, null /*constraints*/, namespaces);
    }

    public static Route MapRoute(this RouteCollection routes, string name, string url, ActionResult result, object defaults, object constraints, string[] namespaces) {
        // Start by adding the default values from the anonymous object (if any)
        var routeValues = new RouteValueDictionary(defaults);

        // Then add the Controller/Action names and the parameters from the call
        foreach (var pair in result.GetRouteValueDictionary()) {
            routeValues.Add(pair.Key, pair.Value);
        }

        var routeConstraints = new RouteValueDictionary(constraints);

        // Create and add the route
        var route = new Route(url, routeValues, routeConstraints, new MvcRouteHandler());

        if (namespaces != null && namespaces.Length > 0) {
            route.DataTokens = new RouteValueDictionary();
            route.DataTokens["Namespaces"] = namespaces;
        }

        routes.Add(name, route);
        return route;
    }

请注意，无需 T4MVC 的帮助，您只需编写以下代码即可在 Controller 命名空间上获得强类型:

 string[] { typeof(MyApplication.Controllers.SnippetsController).Namespace }

理想情况下，我应该补充一点，您根本不必传递命名空间，因为在 MVC.Snippets.Rss() 调用中已经捕获了您针对特定 Controller 的意图。但是，如果不对 T4MVC 进行重大更改，我无法找到一种明显的方法来完成这项工作。

无论如何，请查看并测试更改，然后让我知道它是如何为您工作的。好看的话我就入手了

谢谢!
