using System;
using System.Collections.Generic;
using System.Linq;
using eegscreening.Models.ViewModels;
using eegscreening.Models.DB;
using System.Web.Security;


namespace test.Models.ObjectManager
{

     public class RoleManager : RoleProvider
     {
          public override string[] GetRolesForUser(string username)
          {
               if (username != null)
               {
                    using (EEGScreeningEntities db = new EEGScreeningEntities())
                   
                         {
                              var user = db.aspnet_Users.FirstOrDefault(u => u.UserName.Equals(username, StringComparison.CurrentCultureIgnoreCase) || u.Email.Equals(username, StringComparison.CurrentCultureIgnoreCase));

                              var roles = from ur in user.aspnet_Roles
                                          from r in db.User_In_Roles
                                          where ur.RoleId == r.RoleId
                                          select ur.RoleName;
                         
                              if (roles != null)
                                   return roles.ToArray();
                              else
                                   return new string[] { };

                    if (user != null)
                         return roles.Any(r => r.Equals(roleName, StringComparison.CurrentCultureIgnoreCase));
                    else
                         return false;

          }



          public override void AddUsersToRoles(string[] usernames, string[] roleNames)

          }

          public override string[] FindUsersInRole(string roleName, string usernameToMatch)
          {
               throw new NotImplementedException();
          }

          public override string[] GetAllRoles()
