ASP.MVC 4 - Using First QueryString Parameter & Append to Action in Url - c#

I'd like to tidy this url if at all possible.
Curently it looks like this which is returned from an ActionResult GET
http://localhost/Controller/Action?City=SomeCity&GeoLat=00.000&GeoLong=-0.00000494
Here's what I'm trying to achieve
http://localhost/Controller/Action/SomeCity?GeoLat=00.000&GeoLong=-0.00000494
The City parameter isn't used for anything, so manually editing the first url into the second does indeed return the correct data.
I've even tried appending int the City variable to the action, not really ideal.
routes.MapRoute(
"Default",
"{controller}/{action}-{City}/",
new { controller = "House", action = "Location", City = UrlParameter.Optional }
);
Thanks!

You were almost there with the routing change. Add this code BEFORE the default route
routes.MapRoute(
"CityRoute",
"{controller}/{action}/{City}",
new { controller = "House", action = "Location" }
);
Note that I change the url format slightly and removed the optional parameter part (it's not needed)

as I correct understand, this will be solution for you:
routes.MapRoute(
name: "City",
url: "House/Location/{City}",
defaults: new { controller = "House", action = "Location" }
);
Controller:
[HttpGet]
public ActionResult Location(string City, string GeoLat, string GeoLong){ }
what is more - you have to add this before default route:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Account", action = "Index", id = UrlParameter.Optional }
);
at least, now you will be able to achieve GeoLat and GeoLong value, as also City parametr, in your controller method.

To get the url you're after in MVC 4 you have two options
Map a route with a city param:
routes.MapRoute(
"City",
"{controller}/{action}/{city}",
new { controller = "House", action = "Location", city = UrlParameter.Optional }
);
Rename you city param to id and use the default route mapping.
(MVC 5 introduces the RouteAttribute class that allows you to specify mappings on individual Actions.)

Changes to query string in the url

I have an action method that looks like this
public ActionResult MethodName(int num)
{
viewmodel model = GetDetails(num)
return View(model);
}
route config looks like this
routes.MapRoute(
name: "MethodName",
url: "{ControllerName}/{MethodName}",
defaults: new {controller = "controllerName", action="MethodName"}
);
My issue is it gives the URL of
www.mysite.com/controller/Method?message= 78545
I would like to have it as
www.mysite.com/controller/Method/78545
Can anyone please help me with this? How can I achieve this? I have tried making changes to route config with no help. Do I need to make any URL rewriting or will there be a small fix for this in route config?
Thanks.
Change your route mapping to have an optional num parameter:
routes.MapRoute(
"MethodName",
"{ControllerName}/{MethodName}/{num}",
new { controller = "controllerName", action = "MethodName", num= UrlParameter.Optional }
);
If you don't want your parameters to result in a querystring, you need to add optional parameters to your MapRoute. Then you load the parameter with the value you want to pass to the action result.
In the example below, you can access the method by calling it with "controller/action/op1" or "controller/action/op1/op2", you get the idea. (if op1 equals the value 1, the url will look like 'controller/action/1', same for the other parameters)
[ Add Optional Parameters ]
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{op1}/{op2}/{op3}",
defaults: new { controller = "Home", action = "Index", op1 = UrlParameter.Optional, op2 = UrlParameter.Optional, op3 = UrlParameter.Optional }
);

MVC Routing Parameter Not Being Passed

I am trying to do some MVC routing, following online tutorials, but for some reason the routing is not working.
I am trying to do http://www.website.com/news/news-title
The route I am trying to do is below.
routes.MapRoute(
"News",
"{controller}/{url}",
new { controller = "News", action = "Index", url = "" }
);
Within my NewsController I have the following ActionResult.
public ActionResult Index(String url)
{
return View();
}
However, when stepping thorough the code, url is not being populated.
Thanks
== Update ==
Thank you all for your replies.
I have no amended the Route to below
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.LowercaseUrls = true;
routes.Add(new SubdomainRoute());
routes.MapRoute(
"News",
"News/{action}/{slug}",
new { controller = "News", action = "Index" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
This URL works: /news/index/?slug=test-news-title
But this URL does not: /news/index/test-news-title
=== Further Edit ===
It appears my subdomain route is messing with it. If i remove the subdomain route it works fine.
Thanks.
Most likely, your route is too broad. But it depends on how the rest of your routes are configured. You would need to post your entire route configuration (including area routes and attribute routing) in order to reasonably get an answer what is wrong with your route.
However, you can be more specific with this route because you know that it needs to start with /News.
routes.MapRoute(
"News",
"News/{url}",
new { controller = "News", action = "Index" }
);
Also, it probably doesn't make sense to make the URL parameter optional by providing a default value. If you remove url = "", the url parameter is required in the URL. If configured as above, if you just pass /News, it won't match this route. However, as you have it this URL will match.
Finally, make sure this route is placed in the right order. It should be placed before your default route (if you still have it).
You have set for the parameter url the empty string. you should use instead UrlParameter.Optional (or removing it at all if is mandatory):
routes.MapRoute(
"News",
"{controller}/{url}",
new { controller = "News", action = "Index", url = UrlParameter.Optional }
);
You are missing the action part in the MapRoute
routes.MapRoute(
"News",
"{controller}/{action}/{url}",
new { controller = "News", action = "Index", url = "" }
);
Hope this help

default routing not working

In my MVC application, I have following route configuration,
routes.MapRoute(
name: "ProductRoute",
url: "{productName}/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
Now if i give some thing like this, localhost:56789/prd1/Home/Index
The first routing is working.
However if i directly access localhost:56789/Home/Index or any other controller action, like localhost:56789/Account/Login the routing is not working.
Is it because I have a {productName} defined?
For testing purpose how can I add few products like prd1, prd2 along with routing?
Routes are matched against the request in the order they are defined. When a route matching the request is found, no further routes are considered. Thus, you need to list your routes in order of decreasing specificity.
However, your first route matches more requests than your second route, i.e. it is less specific than the second route:
When ASP.NET MVC tries to match the request for Home/Index to your routes, it will match the first route because it will consider Home to be the productName, it will consider Index to be the controller name and the rest of the parameters are not required.
You need to reorder your routes or make the first route more specific. This could be done by putting constraints on the productName parameter.
UPDATE
Without knowing anything about your products and their names, it is impossible for me to suggest an appropriate constraint. Maybe you could use a numeric SKU and have a constraint like
routes.MapRoute(
name: "ProductRoute",
url: "{productName}/{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new { productName = #"\d+" }
);
forcing productName to be numeric.
Alternatively, you could change the url to
"products/{productName}/{controller}/{action}/{id}"
For more on constraints see this link or use Google.
For route configuration
routes.MapRoute(
name: "ProductRoute",
url: "{productName}/{controller}/{action}/{id}",
defaults: new { productName = 'put your method name to get productName over here', controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new string[] { "your namespace of controller" });
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional });

MVC3 maproute without showing action?

If I have the following MapRoute:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
I can have an url like:
blabla.com/Home/Index/123
But what kind of MapRoute do I need to create to be able to do this:
blabla.com/Home/123 or blabla.com/Home/DEADBEEF?
I imagine it involves something along the lines of
"{controller}/{id}/{action}"
Action and id are reversed, and maybe there should be a default action. But how will the MapRoute know which controller should be treated like this?
You probably need something along these lines.
routes.MapRoute(
name: "DefaultRoute",
url: "Home/{action}",
defaults: new { controller = "Home", action = "Index" },
constraints: new { action = "[A-Za-z]*" }
);
or without an action
routes.MapRoute(
name: "DefaultRoute",
url: "Home/{id}",
defaults: new { controller = "Home", action = "Index", id = "" },
constraints: new { id = "[A-Za-z]*" }
);
You will need to make sure that the route name is different than any other routes you have setup and pay attention to the ordering of the routes as other routes that are similar can override each other. In this case make sure you would probably want this before the default route but be aware that it will override it.
As for the not having controller or even the action you can set defaults and do not need them within the route.
As for constraints you can simply add the constraints parameter to the route to set a regular expression for a certain attribute as shown above.
EDIT:
Here are some useful links for more info on routing if you need it.

http://weblogs.asp.net/scottgu/archive/2007/12/03/asp-net-mvc-framework-part-2-url-routing.aspx
Advanced ASP Routing tutorials and examples
You can add a route like this:
routes.MapRoute(
"CustomRoute",
"Home/{id}",
new { controller = "Home", action = "Index", id = "" });
Make sure you place it above the default route. However this route will block all the other actions in HomeController. Since we don't have a constraint on id parameter, the framework can't possibly know if you are referring to an action or an id in your URL. Since this route comes first, it will map it to id parameter.

How can I create a friendly URL in ASP.NET MVC?

How do I generate friendly URLs within the ASP.NET MVC Framework? For example, we've got a URL that looks like this:
http://site/catalogue/BrowseByStyleLevel/1
The 1 is Id of the study level (Higher in this case) to browse, but I'l like to reformat the URL in the same way StackOverflow does it.
For example, these two URLs will take you to the same place:
https://stackoverflow.com/questions/119323/nested-for-loops-in-different-languages
https://stackoverflow.com/questions/119323/
EDIT: The friendly part of the url is referred to as a slug.
There are two steps to solve this problem. First, create a new route or change the default route to accept an additional parameter:
routes.MapRoute( "Default", // Route name
"{controller}/{action}/{id}/{ignoreThisBit}",
new { controller = "Home",
action = "Index",
id = "",
ignoreThisBit = ""} // Parameter defaults )
Now you can type whatever you want to at the end of your URI and the application will ignore it.
When you render the links, you need to add the "friendly" text:
<%= Html.ActionLink("Link text", "ActionName", "ControllerName",
new { id = 1234, ignoreThisBit="friendly-text-here" });
This is how I have implemented the slug URL on my application.
Note: The default Maproute should not be changed and also the routes are processed in the order in which they're added to the route list.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home",
action = "Index",
id = UrlParameter.Optional
} // Parameter defaults
);
routes.MapRoute("Place", "{controller}/{action}/{id}/{slug}", new { controller = "Place", action = "Details", id = UrlParameter.Optional,slug="" });
you have a route on the global.asax
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = ""}
// Parameter defaults )
you can define your own route like :
controller is the cs class inside the the controllers folder.
you can define your id - with the name you choose.
the system will pass the value to your actionResult method.
you can read more about this step here : http://www.asp.net/learn/mvc/tutorial-05-cs.aspx
