具有相同 Action 名称和不同参数的 C# MVC 路由

Question

我在 SurveyController 中有两个方法:

public ActionResult Index(string surveyId, string surveyWaveId, string programId)

和

public ActionResult Index(string hash)

我希望能够去:

调查/索引/{string} 或调查/索引/{string}/{string}/{string}

并根据提供的参数数量路由到正确的操作。这在 MVC5 中可行吗？我的 RouteConfig 中也有这个。

routes.MapRoute(
            name: "SurveyEmailLink",
            url: "Survey/Index/{hash}",
            defaults: new { controller = "Survey", action = "Index"},
            namespaces: new[] { "Cobalt.Controllers" }
            );

        routes.MapRoute(
            name: "SurveyIconLink",
            url: "Survey/Index/{surveyId}/{surveyWaveId}/{programId}",
            defaults: new { controller = "Survey", action = "Index" },
            namespaces: new[] { "Cobalt.Controllers" }
            );

        routes.MapRoute(
             name: "Default",
             url: "{controller}/{action}/{id}",
             defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
             namespaces: new[] { "Cobalt.Controllers" }
             );

提前致谢!

最好(也是最简单)的选择是为您的操作命名，以更多地说明它们的用途...除非 Index 确实是这两者的合适名称。

    routes.MapRoute(
        name: "SurveyIconLink",
        url: "Survey/Icon/{surveyId}/{surveyWaveId}/{programId}",
        defaults: new { controller = "Survey", action = "Index" },
        namespaces: new[] { "Cobalt.Controllers" }
        );

    routes.MapRoute(
        name: "SurveyEmailLink",
        url: "Survey/Email/{hash}",
        defaults: new { controller = "Survey", action = "Index"},
        namespaces: new[] { "Cobalt.Controllers" }
        );
