c# User.IsInRole Namespace

Question

Note, I am using c# MVC 3, I am trying to use this within a class, NOT a controller.

I have the following at top of my program

    using System.Web.Security;

I tried to do the following but get the message:

The name 'User' does not exist in the current context.

Here is my partial code:

     using System.Web.Security;
     ....
     ....

     if (User.IsInRole("Admin"))  
     {

     }

I am thinking that is has to do something with the namespace but looking at the documentation, all I should need is System.Web.Security.

`User` is part of the context or `Page`, where are you trying to access `User`? — Mark Coleman, Jan 09 '13 at 21:03
Sorry, is this an MVC web project? If so add `using System.Web.Mvc;` — Forty-Two, Jan 09 '13 at 21:03
Where is this code? Inside a Controller method? Inside a class? — levelnis, Jan 09 '13 at 21:06
@Forty-Two, Thanks, I am using MVC. I tried to do using System.Web.Mvc but my pogram didn't recognize it. I believe I need a reference. Where do I find the reference at? — Nate Pet, Jan 09 '13 at 21:07
Get yourself a copy of ReSharper - it'll prompt you to add missing using statements automatically (amongst a great many other things) — levelnis, Jan 09 '13 at 21:07
See [How to: Add or Remove References By Using the Add Reference Dialog Box](http://msdn.microsoft.com/en-us/library/wkze6zky.aspx). But if a reference does not already exist, then I doubt this will fix your problem. — JDB, Jan 09 '13 at 21:09

Try first : while executing the view, check the following in controller HttpContext.Current.User.IsInRole("Admin") - this line check your value.

It should return a bool value if you have current HttpContext loaded.

Solution #2: Look at the default mvc3 project:

Context.User.IsInRole("Admin")

instead of Page.User.IsInRole("Admin").

In addition: you may check this post about how to set usage of roles - User.IsInRole(" ") without using Membership.

Look for the following usage with ASP.NET MVC Membership classes :

Thanks. I do not see Context.User.IsInRole("Admin"). Note that I am using MVC and this code is not a controller but a class file. Please advise. Thanks – Nate Pet Jan 09 '13 at 21:26
You would need to use `Membership` in order to be able to do Role checks in class. – Yusubov Jan 09 '13 at 21:40
Where can I find out more on Membership. – Nate Pet Jan 09 '13 at 21:43
i have provided references in my answer, check them – Yusubov Jan 09 '13 at 21:44

add using System.Web.Mvc; That should do it

So based on your comment, I'm going to assume you are working in a class that is not a Controller, but is inside your MVC project. So you should be able to do what you are attempting like so

if(HttpContext.Current.User.IsInRole("Admin"))
    {
      //...         
    }

Right click `references` in solution explorer and choose "add reference". Click .NET tab and find the System.Web.Mvc component name – Forty-Two Jan 09 '13 at 21:10
If you have to add a reference to System.Web.Mvc, then I don't think that you are working with a standard MVC project. Is it possible this code is in a Model layer that is a code library? – JDB Jan 09 '13 at 21:12
@Cyborgx37 - I am using MVC but this code is inside of a class. Please advise. Thank you. – Nate Pet Jan 09 '13 at 21:25

You say you are using MVC, but System.Web.Mvc should have been referenced by default (otherwise an MVC project wouldn't compile). Did you add a class library to your solution (perhaps as a DataTier or Model or whatchamacallit)? – JDB Jan 09 '13 at 21:39

Use System.Web.HttpContext.Current.User.IsInRole("yourRole")

Hope it will help :)
