query IEnumerable array and select all x.profilenames

Question

ok so this is maybe very simple but I just can not see where I am going wrong so any help is grateful

I have a model of this:

public IEnumerable<SelectedProfiels> profiles { get; set; }
public class SelectedProfiels
{
    public int Identifer { get; set; }
    public string ProfileName { get; set; }
}

and then I am trying to read from this

i am then building an array called selectedProfiles,

I then have this code

 var pro = from s in selectedProfiles select s;

What im wanting to do is find all the ProfileName's and assigned them there on ViewBag.[i] or just there own string variable

I have a model collection like this

var userd = new User()
            {
                ID = i.FirstOrDefault(),
                Type = t.FirstOrDefault(),                
                AuthorityLevel = a.FirstOrDefault(),
                Language = l.FirstOrDefault(),               
                Profiles = pro,               

            };


public IEnumerable<SelectedProfiels> profiles { get; set; }

public class SelectedProfiels
{
    public int Identifer { get; set; }
    public string ProfileName { get; set; }
}

I then pass userd to a new page:

return RedirectToAction("test", "Account", userd);

 public ActionResult test (Userm)
        {
            ViewBag.d = m.profiles;

            return View();
        }

any help please

So, given your linq query:

 var pro = from s in 
           selectedProfiles 
           select s;

You can use Linq to generate an IEnumerable from pro, like:

var selectedProfiles = pro.Select(p => p.ProfileName).ToList();

Then, you can use selectedProfiles to populate the array you desire:

string[] newStrings = selectedProfiles.ToArray();

I understand what you have put here full but I get cannot implicitly convert 'generic list to IEnumerable – Mich Jun 18 '15 at 14:01
Since you're only interested in the `ProfileName`, did you try to just make `profiles` be `IEnumerable`? – Mark C. Jun 18 '15 at 14:02
I have added extra code as to how the collection is built – Mich Jun 18 '15 at 14:05
this 'string[] newStrings = selectedProfiles.ToArray();' works outside of the 'var used = new user()' if say i try 'Profiles = selectedProfiles.ToArray();' – Mich Jun 18 '15 at 14:09
I don't see how `User` is involved with this at all. Your question was very explicit, how to get the `ProfileName` values from an `IEnumberable` into an array..This is the code that does it. If something else doesn't work then that's another question. – Mark C. Jun 18 '15 at 14:11
yes but im want to pass back userd to to the return method without the profiles being within this passing them in to a need array is ok but it needs to be within userd – Mich Jun 18 '15 at 14:17
It sounds like you need to add a property on your ViewModel for the array (or another List) – Mark C. Jun 18 '15 at 14:20
I think I am finally getting there :) – Mich Jun 18 '15 at 14:25
Good! I'm glad to hear it. I hope you do get it. – Mark C. Jun 18 '15 at 14:25
I am thanks a lot closer to doing what I want it to do now so big thanks :) – Mich Jun 18 '15 at 14:52

Instead of

select s

Just use

select s.ProfileName

yes but when you trying to assign that to a string you get cannon implicitly convert type IEnumerable generic string to IEnumerable selectedprofiles – Mich Jun 18 '15 at 13:05
@Mich Can you show us exactly what it is you're trying to do with the IEnumerable? – Drew Kennedy Jun 18 '15 at 13:12
the result is an IEnumerable, that's what the OP wanted, or not? – LInsoDeTeh Jun 18 '15 at 13:13
I think he wants to pass the `ProfileName` for each item in the `IEnumerable` into an array.. (from `pro`) – Mark C. Jun 18 '15 at 13:16
@MarkC. iv added the other c# im trying to use – Mich Jun 18 '15 at 13:51
