家庭控制器中的重载方法和ASP.NET MVC中的路由问题 [英] Method over loading in homecontroller and routing issue in asp.net mvc

问题描述

我有家庭控制器.我的家庭控制器有两种索引方法，一种没有参数，另一种带有参数.就像

i have home controller. my home controller has two index method one with no parameter and one with parameter. it is like

    public ActionResult Index()
    {
        ViewData["Message"] = "Welcome to ASP.NET MVC!";
        return View("index");
    }

    public ActionResult Index(int a)
    {
        ViewData["Message"] = "Welcome to ASP.NET MVC! and Your Age is " + a;
        return View();
    }

我在global.asax中仅定义了两个路由条目，例如

i have define only two route entry in global.asax like

            routes.MapRoute(
                "Default1", // Route name
                "{Home}/{ID}", // URL with parameters
                new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

            routes.MapRoute(
                "Default", // Route name
                "{controller}", // URL with parameters
                new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

我希望当我输入 http://localhost:7221 或 http://localhost:7221/home 之类的url时，再使用没有参数的index()方法家用控制器的控制器应触发并

I want that when i type url like http://localhost:7221 or http://localhost:7221/home then index() method with no param of home controller should fire and

当我键入 http://localhost:7221/home/77 时，应该触发带有home控制器参数的index(int a)方法.但是我收到错误提示，为什么我输入两种指定的网址.错误消息是在以下操作方法之间，当前对控制器类型"HomeController"的索引"操作请求是不明确的:类型BeginnerMVC.Controllers.HomeController上的System.Web.Mvc.ActionResult Index()类型BeginnerMVC.Controllers.HomeController上的System.Web.Mvc.ActionResult Index(Int32)

when i type http://localhost:7221/home/77 then index(int a) method with param of home controller should fire. but i am getting error why i type two kind of url i specified. the error message is The current request for action 'Index' on controller type 'HomeController' is ambiguous between the following action methods: System.Web.Mvc.ActionResult Index() on type BeginnerMVC.Controllers.HomeController System.Web.Mvc.ActionResult Index(Int32) on type BeginnerMVC.Controllers.HomeController

我无法捕获该错误.我的路由代码有什么问题.请帮忙.谢谢

i am not being able to catch the error. what is wrong in my routing code. please help. thanks

推荐答案

您不能在MVC中将方法重载与操作一起使用.如果您详细说明了要实现的目标，则将获得有关如何做到这一点的建议.

You can not use method overloading with actions in MVC. If you elaborate what you're trying to achieve, you would get advices on how to do that.
