This is a very basic question, yet I cannot find any clear, simple, direct answers.
I have a basic MVC4 app with 1 HomeController.cs file. I want to create a second Controller.cs file to put more code into so HomeController doesn't turn into spaghetti code.
So obviously step 1 is to add a new controller. I assume the next step is to add some stuff to RouteConfig.cs.
What do I need to add to RouteConfig.cs to utilize a new Controller.cs?
You shouldn't need to add anything. HomeController requires a line of code in your RouteConfig to be set as the default controller (for when users navigate to the site root), but any other controller should be accessible with the default routing.
Just create a controller, add some actions, and you should be able to route to it with the format Controller/Action or using the routing helper functions.
What does your routes file look like?
Normally, there's a default route:
routes.MapRoute("default",
"{controller}/{action}/{id}",
new { controller = "Home", action="Index" }
);
That means that so long as you add a new controller with the Controller suffix, MVC will make sure the routing engine sees your controller, and as long as your URL follows the above structure, requests made in that format will be routed to the appropriate controller.
We normally send it to a different view which submits to different controllers, or add a reference in your current controller if your just wanting to call certain methods in your current home controller.
What you really need first after creating a new controller is to add a new action (if it's not added automatically) and then add a new View for your new action.
You need to touch your routes only if you are about to process some specific parameters which dont match your default settings

I believe this should have been asked and answered somewhere already, or is just a very basic thing, but I did not manage to find anything at all, I am guessing I might be querying my search wrong.
Either way, what I want is to display Index page without any domain paths.
What I want:
http://localhost:50024/
How I was able to make it with domain paths:
http://localhost:50024/Home/Index
I made a HomeController.cs and added a GET method for the Index view... which is in the Home folder under Views folder, and of course that creates domain paths. I do not care if I have to make extra controller or something, I just want it to display my index page without any paths. Thanks in advance!
You must set default values for the parameters in the route configuration in global.asax, similar to this:
routes.MapRoute( "Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults );
So that when the route parameters are missing, the routing system points the request to the desired controller and action.
just tested myself so i know it works
Test
obviously replace with what you have for the defaults in your routing if you have modified them or something
If all you're after is the "root" URL, you can also use ~/, like so:
Home
The Razor engine is smart enough to parse that URL in place, without needing to use the UrlHelper class.
I've created a controller, called ClientController.cs and VS automatically created the necessary View files in /Views/Client. But I wanted to get these pages in a different URL... So, it is /Client but I need it at /admin/client.
What should I change?
Thank you!
It's not clear what your functionality will be in the long run, but here are a few options that allow you to get the URL format you want:
Perhaps you want a controller called "Admin" and an action called "Client". This would give you a path of /Admin/Client by default
Alternatively, you can change your route maps. For example, the following with route /Admin/Client to the Index of your Client controller:
routes.MapRoute(
"Default", // Route name
"Admin/Client/{action}", // URL with parameters
new { controller = "Client", action = "Index" } // Parameter defaults
);
Or maybe even go a far as using "Areas", depending on what you need. Have a Google of that if you're interested in learning more
If you want it to be admin/client, then using the default routing you should create an Admin Controller with an ActionResult method called Client. Your views folder should have an admin folder with your client view inside.
I haven't done a lot of MVC but i believe this is what you do.
I just watched the Pluralsight video on URL routing in ASP.NET MVC 3. I'm still a bit confused.
That image shows how my views are set up. I have a controller for each view. Perhaps I misunderstood something but when I did this I thought by adding the Portfolio view and controller instead of going to /home/portfolio it would just take me to /portfolio but it didn't. Now when I click on the portfolio link it takes me to /portfolio/portfolio.
Am I misunderstanding something about the way routing works in ASP.NET or am I just forgetting something?
It takes you to Portfolio/Portfolio because that is how you named the setup. The first one is the name of your controller (without controller in the name) PortfolioController. The second one is the name of your ActionResult, Portfolio which returns Portfolio.cshtml. If you wish to only see /Portfolio you could always have the PortfolioController use
public ActionResult Index(){ return View(); }
and then rename Portfolio.cshtml to Index.cshtml and you should be good to go.
when you have localhost/portfolio you that will call default action of portfolio which will be Index by default and you will see that view ,since you don't have view for that and you can make one
you can access your portfolio action in your portfolio controller by /portfolio/portfolio
because it follows the default route which is in routConfig.cs in app_start folder
if you want to get the same result for /portfolio/portfolio just with /portfolio you can add a route like this in your routeconfig
routes.MapRoute(
name: "portfolio",
url: "portfolio/{action}",
defaults: new { Controller = "portfolio", Action = "portfolio" }
);
be careful to write that before default route,because when it match the first route it would not check for other
sorry my English is not good
Rename the action and view to Index.
Pretty new to MVC I have a page on an open source application I have downloaded that is at the url...
http://localhost:51930/admin/login?databaseIssue=true
Obviously Im trying to find which controller and view this maps to in the application. How do I work this out? What should I search for and where to look?
Also how do I work out which actions process this view?
This should help you out. This tool is awesome!

This guide should get you started. Basically you work with a collection of routes and their arguments, in the global.asax.cs file. The guide there also has a section on custom routes.
By the defaulting routing rules, it's {controller}/{action}/
Which would make the controller in http://localhost:51930/admin/login?databaseIssue=true admin and the action Login.
By convention, MVC routes are generated in form
{app_base}/{controller}/{action}
Check out this stackoverflow question for more information.
So in your case, you'll want to look for an admin.cs class in your Controllers folder.
global.asax is where the route mapping is defined.
You'll see/set something like:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
so by default, your example maps to admin = {controller} and login = {action} and login action method would take the databaseissue=true bit as a parameter.
All these answers are good, except in the case where someone may have created a custom route to the specific url in question. By default, they are all correct, but if a custom route was setup, it could be going to the StackController and referencing the Overflow action.
Like Jamie R Rytlweski suggested above, reference RouteDebugger in your project, add the hook in your global.asax and try going to that page, it will show you a listing of all the routes defined in your application and then show you which routes the current page matches
In Visual Web Developer when I "run" my Controller (TestApp) I come up with this:
http://postimage.org/image/iggcs6hw/
I've tried adding "/TestApp" on the end of the local host address in the address bar and that gave me this result:
http://postimage.org/image/ih078cf8/
I don't think I've misspelled anything. Forgive me if this question is a stupid one, just trying to get my feet off the ground :D.
Make sure you have renamed the default ~/Views/Home folder that was generated when you created your project into ~/Views/TestApp folder. As far as the first error message is concerned make sure you have modified the default routes in Global.asax to make the TestApp controller the default one instead of Home:
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "TestApp", action = "Index", id = UrlParameter.Optional }
);
So to sum up:
Make sure that you have an Index.aspx view inside the ~/Views/TestApp folder.
Make sure that you have set the TestApp controller in the default route in Global.asax
Make sure that your TestApp controller has an Index action
Now you will be able to call your application like this: http://example.com/ which will automatically call the Index action on TestApp controller which will render the ~/Views/TestApp/Index.aspx view.
Make sure your views are in the /Views directory. MVC follows a strict folder structure and this happens when it can't find something.
When adding a new view or controller to an MVC project, it's best to use the wizard provided for that purpose.
