Get role name out on site

Question

I'm trying to show a user profile on my site.

For example: "Rank: Owner" But I don't know how to display the rank name. This is the code I currently have:

<p>@if (Model.Roles.Any() != false)
             {

             <b>@Model.Roles.Any()</b>

             }
             else
             {
                 <b>Member</b>
             }
    </p>

But that does only give me this:

System.Collections.Generic.List`1[Microsoft.AspNet.Identity.EntityFramework.IdentityUserRole]

So what do I need to get my role name out?

`if(Model.Roles.Any()!= null)` is always true. instead `if(Model.Roles.Any())` — tchelidze, Jan 09 '16 at 12:55
@tchelidze I'm doing that because that if it is null then they get member. And it is the ussal structure — UnScope, Jan 09 '16 at 12:58
note that `Model.Roles.Any()` can not be null, since `bool` is not nullable type. If `Model` or `Model.Roles` can be null, use [null propagation ](http://davefancher.com/2014/08/14/c-6-0-null-propagation-operator/) instead `Model?.Roles?.Any()` — tchelidze, Jan 09 '16 at 13:02
I believe its list of roles. Try creating a method to return string representation of array of roles — Anup Sharma, Jan 09 '16 at 13:26

First of all @Model.Roles is a list of type IdentityUserRole. So if you wish to see something from that collection you have to iterate it.

// this will never generate readable output, it will always print something like this: System.Collections.Generic.List`1[Microsoft.AspNet.Identity.EntityFramework.IdentityUserRole]
<b>@Model.Roles</b>

Second: the type IdentityUserRole doesn't contain any property that contains the rolename. Only the roleid and the userid. I think you have to get those from somewhere else

Try this code

public static class Extension
{
   public static string GetRoleList(this List<Microsoft.AspNet.Identity.EntityFramework.IdentityUserRole> roles)
   {
      string rolelist="";
      if(roles.Count==0)
         return "None";
      foreach (var item in roles)
      {
         rolelist+=item+",";
      }
      return rolelist.TrimEnd(',');
   }
}

and then use this in view as

<b>@Model.Roles.GetRoleList()</b>

When i'm adding it it' says: "Non-invocable member 'System.Collections.Generic.List.Count' cannot be used liek a method. – UnScope Jan 09 '16 at 13:51
Sorry My bad. Remove the method specifiers () from count. – Anup Sharma Jan 09 '16 at 13:53
Then it says: Error 1 Extension method must be static – UnScope Jan 09 '16 at 13:55
Yes that's true. Both class and method needs to be static – Anup Sharma Jan 09 '16 at 13:56
So what should i do then? :3 – UnScope Jan 09 '16 at 13:57
please add static modifier in both class and method. I've made necessary changes – Anup Sharma Jan 09 '16 at 13:58
I'm not sure how to do that :/ – UnScope Jan 09 '16 at 13:59
Isn't working, it's right to place it into ManageViewModels right? – UnScope Jan 09 '16 at 14:03
Umm, Best will be to create new Class file and then paste it – Anup Sharma Jan 09 '16 at 14:04
Isn't there annother way to get the role name? :3 – UnScope Jan 09 '16 at 14:08
There are a few more complicated ways. Is it not showing any output? What are you getting when you break-point in method? – Anup Sharma Jan 09 '16 at 14:12
