Question

我的webapp中有一些链接如下：

localhost:12345/?something=1
localhost:12345/?something=2
localhost:12345/?something=3
localhost:12345/?something=4

最后的每个数字都是一个id，我需要传递给我的控制器以显示与之相关的信息。

我知道我需要在routes.MapRoute页面中创建一个新的global.asax，但我不太确定如何去做。我试过这个：

routes.MapRoute(
    "Id", // Route name
    "{controller}/{action}/{*Id}", // URL with parameters
    new { controller = "Home", action = "Id", Id = "" } // Parameter defaults
);

--- --- EDIT

我只是通过以下方式成功让每个人都喜欢显示：

routes.MapRoute(
    "IdRoute", // Route name
    "{Id}", // URL with parameters
    new { controller = "Home", action = "Index", id = 1 } // Parameter defaults
);

这确实有效，但是，这仅适用于一个id（特别是1）。我不太清楚如何解决这个问题，但我需要我：

localhost:12345/?something=1

显示id 1的信息，

localhost:12345/?something=2

显示id 2的信息，

localhost:12345/?something=3

显示id 3的信息。

我将会有数百个ID，因此编写某些内容并不是一个方便的选择。到目前为止我没有运气。任何帮助将非常感激！谢谢！

        routes.MapRouteWithName(
            "RootName",
            "{id}",
            new { controller = "Home", action = "Index", id = 1 });

这将生成类似localhost / 1的链接如果你想要这种链接localhost /？id = 1 然后：

        routes.MapRouteWithName(
            "RootName",
            String.Empty,
            new { controller = "Home", action = "Index"});


public ActionResult Index(int id)
    {
        //do something with id, make query to database whatever

        // u usually have model class so you would fill model with your data
        var model = new YourModel();
        //...
        return View("Index", model);
    }

如果你有以下Action，比如HomeController：

public ActionResult SomeAction(int Id)
    {
        return View()
    }

您可以使用以下任何一种途径：

//* For Id = 3 this will return path "Home/SomeAction/3" 
routes.MapRoute(
                name: "First",
                url: "{controller}/{action}/{Id}",
                defaults: new { controller = "Home", action = "SomeAction", Id= UrlParameter.Optional}
            );


//* For Id = 3 this will return path "SomeAction/3" 
routes.MapRoute(
                name: "First",
                url: "{action}/{Id}",
                defaults: new { controller = "Home", action = "SomeAction", Id= UrlParameter.Optional}
            );

//* For Id = 3 this will return path "Home/SomeAction(3)" 
routes.MapRoute(
                name: "First",
                url: "{controller}/{action}({Id})",
                defaults: new { controller = "Home", action = "SomeAction", Id= UrlParameter.Optional}
            );


//* For Id = 3 this will return path "LadyGaga/SomeAction/3" 
routes.MapRoute(
                name: "First",
                url: "LadyGaga/{action}/{Id}",
                defaults: new { controller = "Home", action = "SomeAction", Id= UrlParameter.Optional}
            );

使用global.asax路由时出现问题
