Running an action method on every view - asp.net

I want to show the version info of the current project on every page.
The way I do it in the moment is like this:
Inside the Index method of my homecontroller:
ViewBag.Version = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version;
Inside the _layout.cshtml(masterpage):
#ViewBag.Version
The Problem here is, it will only displayed once, but I want to display the Version on every page/view.
This is my routing configuration:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
Do I have to change something here ?
Ty for helping

Why not just call
#System.Reflection.Assembly.GetExecutingAssembly().GetName().Version;
on the _Layout.cshtml view?
MVC has a different launch context and a work around is needed to text the version:
#typeof(HomeController).Assembly.GetName().Version
HomeController could be replaced with any other type in the assembly the MVC application assembly. See this question for more info.

Just put this in the Layout.
<label>#System.Reflection.Assembly.GetExecutingAssembly().GetName().Version</label>

Some Controllers not going to default Index action

I have a MVC project. I added a few controllers; over time edited in some code some controllers. Might have done something where I landed up in the following problem and now I do not know how to fix it.
Now http://server/Controller1 correctly executes Index action. But http://server/Controller2 does NOT execute the Index action; instead I get "The Web server is configured to not list the contents of this directory." http://server/Controller2/Index works as expected.
I have gone through similar questions. As you can see Controller1/ routing is happening properly. So it is not IIS config. Controller2 has index() function; it is not route config issue as well; I have not added any specific route for Controller1 or Controller2. The route is basically the default route
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
It sounds like you may have a folder in your website called Controller2, as the webserver is trying to list its contents

Trying to display Custom View in MVC app but it says requested URL not found

I am new to azure, MVC and also ASP.NET. I am writing MVC Cloud service with ASP.NET web role. Please help me with this problem
When I create the application there are default views but I wanted to see my view so I set my view as start page. I also changed the values in RegisterRoutes method
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "User", action = "AddUser", id = UrlParameter.Optional }
);
}
When I run the app, it gives HTTP 404 error because it could not find request URL : /Views/User/AddUser.cshtml
In MVC you don't put the view in the URL to get it rendered.
This won't work: /Views/User/AddUser.cshtml
As you've correctly put in your question the default route is {controller}/{action}/{id} with id being optional.
So assuming that User is your controller, i.e. you have a class called UserController, which looks something like:
namespace My.Controllers
{
public class UserController : Controller
{
which has an action on it called AddUser:
public ActionResult AddUser()
{
// implementation logic
return View();
}
Then the default route will display your view when it processes the URL /User/AddUser
In MVC 5, this looks something like:

Every request to be routed to a single controller - MVC

I was asked this question in an interview.
Can someone please let me know the answer for this.
"I have an MVC application and I want all the requests to be targeted to a single controller, which would then decide the actual controller to which the request to be sent to and that controller should actually handle the request. How do I achieve this?"
Thanks,
Vijendra
This seems like a bad idea, but if you wanted to do something like that you would do it like this in RouteConfig.cs
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{action}/{id}",
defaults: new {
controller = "Base",
action = "Index",
id = UrlParameter.Optional }
);
}
}
And you would have a matching BaseController.cs

Make index.html my landing page in asp.net mvc for christmas and new year

I want to put a greeting as front page for some days on my site for Christmas and new year, but its still taking to my asp.net mvc home.
please how to do it, or I need to change my /home/index page for it.
Regards
Open up the properties of the project, and click on the web tab. Select the Specific Page radio button. Simply type in the url you want to use!
Change your landing page in your global.asax file
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}",
defaults: new { controller = "Home", action = "YOUR ACTION" }
);
}
You need to edit the file "RouteConfig.cs" under the folder "App_Start". Then change your controller and action to Home and Index. The RouteConfig.cs file should look like this:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}",
defaults: new { controller = "Home", action = "Index" }
);
}
Rename the existing index.cshtml or index.aspx to index1.cshtml/.aspx which is under views/home. then put your index.html and run the application

default page issue with 4.0 ASP.NET and MVC mixed mode website

I am converting a classic ASP.NET 4.0 site to also use MVC. Over time I am migrating the ASP.NET code to MVC, but during the transition both technologies will be in use.
If I navigate to the default page (ie, http://mywebsite.com/), then MVC routing is taking over and returning the following message.
This request has been blocked because sensitive information could be
disclosed to third party web sites when this is used in a GET request.
To allow GET requests, set JsonRequestBehavior to AllowGet
If I use http://mywebsite.com/default.aspx, then everything works fine.
My route config looks like...
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//ignore aspx pages (web forms take care of these)
routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
Notice I am ignoring .aspx page requests, so these requests get ignored by the MVC pipeline. However, I need 'no page specified' default requests to process default.aspx. How would I change the above code or configure the site/IIS to make this happen?
I removed the default route and now the behavior is as needed.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//ignore aspx pages (web forms take care of these)
routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { id = UrlParameter.Optional }
);
}
