MVC routing - specify id without action

I would like to specify an id without having to include the index action.
Here is what I have tried:
routes.MapRoute("Upload", "Upload/{id}",new { controller = "Upload", action = "Index" });
This gives a 404 error. The url will be something like site.com/Upload/123

Probably you need to put the code before the Default route. MVC check routes from the any route after default won't work

C# MVC utilising parameter on default route

I'm using MVC 4.
My default route on my site is Home/Index so when the user enters the URL www.example.com it goes to that route.
Could you let me know if it is also possible to receive a parameter appended to that URL i.e. www.example.com/param? It works if I use www.example.com/Home/Index/param but that's not ideal.
I'm guessing its something I need to add to the Global.asax but I can't find examples anywhere.

context.MapRoute(
"Home_all",
"/{*actions}",
new { controller = "Home", action = "Index"}
);
But be aware that route will match all urls , so you need to register it at last :) That Routing will be called like this in your Home Controller for example... Actions will be a part from the url, and you can even add some parameter in the query string
public ActionResult Index(string actions, string id)
{
}

How do I change the route of an ASP.NET MVC controller?

I have a typical ASP.NET MVC controller, but I just want to change its route. The default route now is:
Blog/{controller}/{action}/{id}
I want to change the route of a specific controller to
Blog/Admin/{controller}/{action}/{id}"
I tried to achieve this by adding the Route, RouteArea and RoutePrefix attributes to the controller but without any success.
How can I achieve this?

Add this route prior to the default
routes.MapRoute(
name: "BlogAdmin",
url: "Blog/Admin/{action}/{id}",
defaults: new { controller = "YourSpecificControllerName", action = "Index or other default action name", id= UrlParameter.Optional });
Since this is for a specific you don't need {controller} part in your url. If you still want to specify it change the url argument to "Blog/Admin/YourSpecificControllerName/{action}/{id}" where YourSpecificControllerName is the name of your controller.
Also since the order of rote registration matters make sure that this route registered prior to the the default one

How can I route requests to a page controller for routes that don't exists in ASP.NET MVC 4

How can I route requests to a default PageController for routes that do not map to a controller or action? But for routes that do match a controller or action, have those behave as normal, using ASP.NET MVC?
Basically I have a CMS backend that I have developed and I need to be able to inspect the route, to see if it matches a route for a page, stored in the database and if so, forward the request to the default PageController, which handles loading the pages content from the database. There are also CORE pages, that do have their own Controllers and Actions defined, and if you enter a route that doesn't match a pages route in the database, I need it to revert to the default behavior of ASP.NET MVC and look for the {controller}/{action}.
I have searched and searched online, with not much luck finding how I could do this. Any help would be greatly appreciated.

Set your routes up so the ones for existing controllers and actions are first, then have a catchall that maps to your PageController:
// More specific routes go here
routes.MapRoute(
null,
"{controller}/{action}/{id}", // URL with parameters
new { action = "Index", id = UrlParameter.Optional }, // Don't put a default for controller here
// You need to constrain this rule to all of your controllers, so replace "ControllerA" with an actual controller name, etc
new { controller = "ControllerA|ControllerB|ControllerC" }
);
routes.MapRoute(
null,
"{*path}",
new { controller = "Page", action = "Index" }
);
Anything that isn't matched by the first rule and any rules you put before it will fall back to your page controller, with the path in a path parameter on your index action method.

Understanding routing in ASP.NET MVC

I'm trying to wrap my mind around the way ASP.NET MVC implements routing.
From what is my current understanding, it seems my route string much have a "{controller}" and "{action}", otherwise it doesn't work?
How would I define the route that using a SearchController and Search action taking both SearchKeywords and SearchCaseSensitive arguments had the following URL?
domain/SearchKeywords/CaseSensitive
Even simpler, how do I map domain to controller SearchController and to Search?

Values for the controller and action tokens are required. You have 2 options for providing the values:
1) Using {controller} and {action} tokens on the URL template. e.g.:
routes.MapRoute(null, "{controller}/{action}");
2) Using default values for controller and action. e.g.:
routes.MapRoute(null, "some-url",
new { controller = "Search", action = "Search" }
);
How would I define the route that
using a SearchController and Search
action taking both SearchKeywords and
SearchCaseSensitive arguments had the
following URL?
domain/SearchKeywords/CaseSensitive
The URL host (or domain) is not considered by the routing system, only the application relative path. You can do this:
routes.MapRoute(null, "{SearchKeywords}/{CaseSensitive}",
new { controller = "Search", action = "Search" }
);
You can also provide defaults for SearchKeywords and CaseSensitive, if you want to make either of them optional.

You can add controller = "Search", action = "Search" to the defaults (the last parameter).
The routing engine will use values in defaults to fill in for parameters that aren't in the URL.

If you want to have a 'domain' parameter in your route, you must put this at the top of the route registration. The 'domain' parameter in the second anonymous object is a constraint and here is set to be a regular expression that tests to see if the domain is either of the possible domains "DefaultDomain" or "OtherDomain".
routes.MapRoute("DomainRoute", "{domain}/{controller}/{action}",
new {domain = "DefaultDomain", controller = "Search", action = "Search"},
new {domain = "DefaultDomain|OtherDomain"});
