Did you try this?:

    return RedirectToAction(&quot;action&quot;, &quot;controller&quot;, new { area = &quot;area&quot; });

Your answer was helpful to me. Just wanted to add below:

If you want to redirect from one area to another area, above code works well.

And, if you want to redirect from one area to a controller/view which is not there in the area folder (i.e. in most cases, your front end), you can specify area = &quot;&quot;.

i.e.

    return RedirectToAction(&quot;action&quot;, &quot;controller&quot;, new { area = &quot;&quot; });

Try this 

    return RedirectToAction(&quot;ActionName&quot;, &quot;AreaName/ControllerName&quot;);

This is a simplified version of the code in question, one generic class uses another class with generic type parameters and needs to pass one of the generic types to a method with varargs parameters:

    class Assembler&lt;X, Y&gt; {
        void assemble(X container, Y... args) { ... }
    }

    class Component&lt;T&gt; {
        void useAssembler(T something) {

            Assembler&lt;String, T&gt; assembler = new Assembler&lt;String, T&gt;();

            //generates warning:
            // Type safety : A generic array of T is
            // created for a varargs parameter
            assembler.assemble(&quot;hello&quot;, something);
        }
}

Is there any correct way to pass along the generic parameter to a varargs method without encountering this warning?

Of course something like 

    assembler.assemble(&quot;hello&quot;, new T[] { something });

does not work since you cannot create generic arrays.

Is it possible to solve the &quot;A generic array of T is created for a varargs parameter&quot; compiler warning?

I am having one problem with the PHP json_encode function. It encodes numbers as strings, e.g. 

    array(&#39;id&#39; =&gt; 3)

becomes

    &quot;{ [&quot;id&quot;: &quot;3&quot;, ...)

When js encounters these values, it interprets them as strings and numeric operations fail on them. Does anyone know some way to prevent `json_encode` from encoding numbers as strings? Thank you!

Can anyone please make a comparison of `ASP.NET MVC` vs `Spring MVC`. 

Which technology is better in performance, productivity, maintenance, features,...

ASP.NET MVC vs Spring MVC

I have a POCO class that is being sent to the browser as a JSON string in .NET 3.5 sp1.  I am just using the default JSON serialization and I have some fields that I want to ignore.  I want to put an attribute similar to [System.Xml.Serialization.XmlIgnore] on them so that they are not serialized.

Ignoring a field during .NET JSON serialization; similar to [XmlIgnore]?

I&#39;m basing this question on Fowler PoEAA. Given your familiarity with this text, aren&#39;t the  ViewModels used in ASP.NET MVC the same as DTOs? Why or why not? Thank you.

I have an existing database with a users table, and we are planning to take the database and use it for a new system built in ASP.NET MVC. However, what I am uncertain about is whether or not I am able to create a login system that doesn&#39;t use the built in account controller or a regular membership provider so that we can still use the existing table structure.

So my question is, would this be possible? Or even particularly difficult to do if it is?

What is the most widely accepted way of doing things and the simplest?

I have a shared master page which I am using from 2 different areas in my mvc 2 app.  The master page has an action link which currently specifies the controller and action, but of course the link doesn&#39;t work if I&#39;m in the wrong area.  I see no overload for actionlink that takes an area parameter, is it possible to do?

How to specify an area name in an action link?

    The view &#39;Index&#39; or its master was not found. The following locations were searched:
    ~/Views/ControllerName/Index.aspx
	~/Views/ControllerName/Index.ascx
	~/Views/Shared/Index.aspx
	~/Views/Shared/Index.ascx

I got this error when using ASP.Net mvc area. The area controller action are invoked, but it seems to look for the view in the &#39;base&#39; project views instead of in the area views folder.

I&#39;ve an Admin area and I want only Admins to enter the area. I considered adding the Authorized attribute to every controller in the Admin area. Isn&#39;t there an elegant solution or is this feature not there in the framework itself?

EDIT:
I&#39;m sorry, I should to have mentioned this before. I&#39;m using a custom AuthorizedAttribute derived from AuthorizeAttribute.

How can we set authorization for a whole area in ASP.NET MVC?

I am running into the following error with my ASP.NET MVC 3 project:

&gt; Multiple types were found that match
&gt; the controller named &#39;Home&#39;. This can
&gt; happen if the route that services this
&gt; request (&#39;Home/{action}/{id}&#39;) does
&gt; not specify namespaces to search for a
&gt; controller that matches the request.
&gt; If this is the case, register this
&gt; route by calling an overload of the
&gt; &#39;MapRoute&#39; method that takes a
&gt; &#39;namespaces&#39; parameter.
&gt; 
&gt; The request for &#39;Home&#39; has found the
&gt; following matching controllers:
&gt; MyCompany.MyProject.WebMvc.Controllers.HomeController
&gt; MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController

I have a HomeController in my default controller folder, with a class name of MyCompany.MyProject.WebMvc.Controllers.HomeController.  

My RegisterRoutes method, in my global.asax, looks like:


        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute(&quot;{resource}.axd/{*pathInfo}&quot;);

            routes.MapRoute(
                &quot;Default&quot;, // Route name
                &quot;{controller}/{action}/{id}&quot;, // URL with parameters
                new { controller = &quot;Home&quot;, action = &quot;Index&quot;, id = UrlParameter.Optional } // Parameter defaults
            );
        }

I then have an area called Company, with a HomeController in the default controller folder for the area, with a class name of MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController.

The RegisterArea method in the CompanyAreaRegistration file looks like:

       public override void RegisterArea(AreaRegistrationContext context)
        {
            context.MapRoute(
                &quot;Company_default&quot;,
                &quot;Company/{controller}/{action}/{id}&quot;,
                new { area = &quot;Company&quot;, action = &quot;Index&quot;, id = UrlParameter.Optional }
            );
        }

This is all leading the error I highlighted at the beginning of this post. I am struggling trying to piece together a solution from various other posts, with **NO LUCK**. 

Is it possible to have a HomeController in the default controllers folder and then one in EACH area? If so, do I need to make (assuming I do) changes to my configuration file to make this work? 

Any help would be much appreciated!



Having issue with multiple controllers of the same name in my project

I have added a new Area to my MVC3 project and I am trying to link from the _Layout page to the new Area. I have added an Area called &#39;Admin&#39; that has a controller &#39;Meets&#39;.

I used the visual studio designer to add the area so it has the correct area registration class etc, and the global.asax file is registering all areas.

However, when I use the following 2 action links in a page in the root, I run into a few problems:

    @Html.ActionLink(&quot;Admin&quot;, &quot;Index&quot;, &quot;Meets&quot;, new { area = &quot;Admin&quot; }, null)
    @Html.ActionLink(&quot;Admin&quot;, &quot;Index&quot;, &quot;Meets&quot;, new { area = &quot;&quot; }, null)

When clicking both links, I am taken to the Meets controller in the Admin area, where the application then proceeds to throw an error saying it cannot find the Index page (even though the Index page is present in the Views folder in the Area sub-directory.

The href for the 1st link looks like this:

`http://localhost/BCC/Meets?area=Admin`

And the href for the 2nd link looks like this:

`http://localhost/BCC/Meets`

Also if I hit the link that I expect to be created:

`http://localhost/BCC/Admin/Meets`

I just get a resource cannot be found error.  All very perplexing!  I hope someone can help...


ASP.NET MVC `Html.ActionLink` between &quot;Areas&quot;

I have the following two action methods (simplified for question):

    [HttpGet]
    public ActionResult Create(string uniqueUri)
    {
       // get some stuff based on uniqueuri, set in ViewData.  
       return View();
    }
    
    [HttpPost]
    public ActionResult Create(Review review)
    {
       // validate review
       if (validatedOk)
       {
          return RedirectToAction(&quot;Details&quot;, new { postId = review.PostId});
       }  
       else
       {
          ModelState.AddModelError(&quot;ReviewErrors&quot;, &quot;some error occured&quot;);
          return RedirectToAction(&quot;Create&quot;, new { uniqueUri = Request.RequestContext.RouteData.Values[&quot;uniqueUri&quot;]});
       }   
    }

So, if the validation passes, i redirect to another page (confirmation).

If an error occurs, i need to display the same page with the error.

If i do `return View()`, the error is displayed, but if i do `return RedirectToAction` (as above), it loses the Model errors.

I&#39;m not surprised by the issue, just wondering how you guys handle this?

I could of course just return the same View instead of the redirect, but i have logic in the &quot;Create&quot; method which populates the view data, which i&#39;d have to duplicate.

Any suggestions?

ASP.NET MVC - How to Preserve ModelState Errors Across RedirectToAction?

I have two controllers, both called `AccountController`.  One of them, lets call it `Controller A`, is in an `Area` called `Admin` and the other, lets call it `Controller B`, is not in any `Area` (I guess that means it&#39;s in the default `Area`?).  `Controller B` has an `action method` called `Login`.  I have an `action method` in `Controller A`, which has this line

    return RedirectToAction(&quot;LogIn&quot;, &quot;Account&quot;);

The problem is that I get a `404` when this line gets executed because an attempt is made to redirect to a non-existent `action` in `Controller A`.  I want to call the `action method` in `Controller B`.  Is this possible?
