Populate EntitySet from List<int>

Question

Hello

I have a model that looks like this:

public class UserAdminEditViewModel
{
    public User User { get; set; }
    public IEnumerable<Usergroup> Usergroups { get; set; }
    public IList<int> UsergroupID { get; set; }
    public IEnumerable<User> Users { get; set; }

    public UserAdminEditViewModel() {}
}

And in my post-action in my controller I got:

        [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult UserEdit(UserAdminEditViewModel userobj)
    {
        if (ModelState.IsValid)
        {
            try
            {
                // userobj.User.UsersUsergroups is EnitySet<UsersUsergroups> User.UsersUsergroups
                userobj.User.UsersUsergroups = userobj.UsergroupID;  //  IList<int> UserAdminEditViewModel.UsergroupID

                us.SaveUser(userobj.User);
            }
            catch
            {
                ModelState.AddModelError("SomeError", "errrrrrrrrror");
            }
        }

How can I populate userobj.User.UsersUsergroups with the list of int's that resides in userobj.UsergroupID?

I get:

"Cannot implicitly convert type 'System.Collections.Generic.IList' to 'System.Data.Linq.EntitySet`1'"

Thanks in advance /M

Why not try

for each(var usergroup in userobj.UsergroupID)
{
   userobj.User.UsersUsergroups.Add(usergroup)
}

instead of

userobj.User.UsersUsergroups = userobj.UsergroupID;  //  IList<int> UserAdminEditViewModel.UsergroupID

HTH,
