Change route string url of blog from controller/action/{*Url} to {*Url} - c#

I have my personal blog site which was done using Asp.Net MVC and C# language.
As I have configured RouteConfig with "controller/action/{*Url}" for blog URL where {*Url} could be any text.
Now I want to change the Url pattern from "controller/action/{*Url}" to {*Url}.
Example:
From below Url
https://abcd.co.in/home/newsdetail/abcd-xyz-opqr-stu
To
https://abcd.co.in/abcd-xyz-opqr-stu
I have done the following changes
routes.MapRoute("", "mycontroller/myactionmethod/{*Url}", new { controller = "Home", action = "NewsDetail", Url = "" });
But it is calling every time URL hits my domain.
Please suggest what are the possible solutions that will not affect other functionality or URLs and it should fulfill my requirements.
Thanks in advance.

After a few google search and R&D on Attribute-based routing I have come up with one solution:
Steps:
Need to define that I am using Attribute routing
routes.MapMvcAttributeRoutes();
Remove existing route entry for the Action method.
Set Attribute route entry path above the Action method.
[Route("{Url}")]
Just update the URL in href from previous to just URL.
From
<a href="/home/newsdetail/#item.Url">
To
<a href="/#item.Url">

ActionLink and relative path

I can't find out how to solve this. I have two URLs. These are /my-url-1 and /my-url-2. Both going to different views.
The thing is that I have an ActionLink on /my-url-1's view which should make /my-url-2 and go to that view.
The problem is that ActionLink makes /my-url-1/my-url-2 as the URL and not just /my-url-2.
I was searching two days about how to fix it but couldn't find anything.
PD: I'm not using Areas so please don't tell me that I just should put the "area" parameter as a "".
These are two urls which goes to different controllers and different actions.
View which has the ActionLink (URL:/my-url-1) :
<div class="btn-index-container">
#Html.ActionLink("Url 2", "MyAction", "MyController")
</div>
This ActionLink should render:
Url 2
But it's rendering:
Url 2
where /my-url-1 is my current URL
Route Config
routes.MapRoute(
name: "route1",
url: "my-url-2", //without parameters
defaults: new { controller = "MyController", action = "MyAction" },
);
routes.MapRoute(
name: "route2",
url: "my-url-1", //without parameters too
defaults: new { controller = "MyController2", action = "MyAction2" }
);
So, when I go to localhost:port/my-url-1 it loads MyAction2 which renders a view. This view has inside an ActionLink(described above) which should render a /my-url-2 link.
Well, I've worked inside the MVC framework and I could told you about how Url.RouteUrl or Html.RouteLink works. At the end, the method which create the URL is GetVirtualPathForArea (this method is called before UrlUtil.GenerateClientUrl, which receive the VirtualPathData.cs created by GetVirtualPathForArea, as a parameter) from System.Web.Routing.RouteCollection.cs.
Here I left a link to the MVC source code:
https://github.com/aspnet/AspNetWebStack/blob/master/src/System.Web.Mvc
I found that, my Request.ApplicationPath was changing when I loaded /my-url-1. It was crazy because the application path was /.
At last, the problem was that the /my-url-1 was pointing to a virtual directory created on the IIS some time ago by error.
To know where your IIS configuration file is, please follow the link below:
remove virtual directory in IIS Express created in error
The solution was remove the .vs directory (which contains the config .vs\config\applicationhost.config) and rebuild
I think most of the Helpers that render URLs works more or less in the same way, so I hope it'll useful for all of you!
In your case, maybe no its necesary, just pass the parameters with null values, E.G.
#Html.ActionLink("Español", null, null, new { Lng = "es" }, null)
In this way, the parameters change, and the view is relative, depending on where you are.

Change url (redirection) in asp .NET

I am working on a C# mvc application. In my site I have this url abc.com/About/WhoWeAre, where 'About' is the Controller and 'WhoWeAre' is the action name. But i want this url to be returned as abc.com/About/who-we-are. The problem is I can't name the action containing '-' in it. I tried Url Redirection using HttpContext Response but couldn't find a solution.
If I handle the request in Route Config for 'About/who-we-are' and route it to 'About/WhoWeAre' it is working with the required url in the address bar. But when I make request for 'About/WhoWeAre' it returns the page with the same('About/WhoWeAre') url in the address bar, which duplicates the url. How can I redirect?
Feel free to ask any questions.
Use ActionName Attribute to map the Url. Below is the example
public class AboutController : Controller
{
[ActionName("Who-we-are")]
public ActionResult WhoWeAre()
{
return View();
}
}
You can use the ActionName attribute to rename your actions with characters that are disallowed in C# method names.

MVC manipulate URL (routing), is it possible?

I have a website that use this pattern.
http://www.domain.com/product/...
My question is now, i need to create a subsite that going to be with this URL pattern, i have tried to change the routing without success.
http://www.domain.com/companyname/product/...
How can i inject the companyname in the URL without breaking my current routing?
Thanks
Niden
Three ways:
If it's relatively static, you can follow Andy's advice in the comments and publish the site in a virtual directory, companyname. Assuming you've properly used the UrlHelper extensions to generate URLs, instead of just hard-coding paths, then everything will just work.
You can create a "companyname" area. The default routing for an area is /area/controller/action. So that would get you the URL structure you want. However, areas are somewhat segregated, so you would need to copy controllers and views to the area's directory. Although, you could subclass controllers from the main app in the area to reuse code.
Just change the default route/add a new route:
routes.MapRoute(
"CompanyDefault",
"{company}/{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = "" }
);
// default route here

How to ignore all characters after "controller/action" in an ASP.NET MVC route?

I would like my ASP.NET MVC4 application to only serve the base HTML markup for a specific page, and after that I'm processing everything else on client-side with knockout.js/history.js/AJAX, including the initial page load.
So when someone refers to URL http://example.com/products/list/food/fruits, the MVC router should simply ignore everything what is behind "products/list" and route the request to ProductsController and List action. Then on client-side I will handle the rest and load the requested data accordingly.
I was playing with the route definitions, I tried to completely skip the "products/list" route, I also tried to add a "products/list/*" route, but didn't have success yet.
You can use an asterisk as part of the last variable in a route. For example, when configuring your routes:
routes.MapRoute(
"ProductRoute",
"products/list/{*otherArgs}",
new { controller = "Products", action = "List" });
You can learn more in MSDN's Documentation on routing under the section "Handling a Variable Number of Segments in a URL Pattern"
You will need to create your own route.
Something like this should do the trick:
routes.MapRoute("Products", "Products/{List}",
new {controller = "Products", action = "List"}
);
Note: I´m not sure if the other parameters are required in the route.

route not mapping mvc 3

I am new in mvc and I have a situation where I am convinced that I am mapping a route correctly although it is not.
it is a very basic login form with the option of passing in parameters.
this is the html
<li>Login</li>
and this is the action method in the 'Home' controller
public ViewResult LoginForm(string userName)
{
return View();
}
This is how is my attempt at mapping the route
routes.MapRoute(
null,
"Login/{userName}",
new { controller = "Home ", action = "LoginForm", UrlParameter.Optional }
);
The url is however displaying as follow
/Home/LoginForm?loginUser=user
my aim would be the following
Login/user
Advice perhaps as to why it is not mapping correctly. I have already registered a number of routes in the Global.asax.cs file. Could it have something to do with the order with which they were registered?
Try this:
<li>Login</li>
change the parameter loginUser to userName.
Use userName instead of loginUser
<li><a href='#Url.Action("LoginForm", "Home", new {userName="user"})'>Login</a></li>
You are hitting a different address than the one specified in MapRoute. The mapped route will not fire. Change both the parameter and the action name.
<li>Login</li>
You need to access /Home/Login not /Home/LoginForm. The routing is done automatically if the right address is accessed.
EDIT:
Following your address edit:
As far as I know, you cannot generate a link such as Login/{userName} using Url.Action; if you don't specify a controller, this defaults to Home controller
You can however access the Login/{userName} link directly from the browser (due to the mapped route)
You can create a "static" (i.e. classic) link, passing a hard-coded address:
<li>Login</li>
Please note that the userName added/removed per JavaScript.
