Except between two table with entity freamwork in asp.net MVC

Question

I have three table A , B , C;

//Table A
 public class Question
    {
        [Key]
        public int ID { get; set; }

        [Required]        
        public string Name { get; set; }

     }
//Table B
public class Answer
    {
        [Key]
        public int ID { get; set; }

        [Required]        
        public string Name { get; set; }

        [Required]        
        public int QusetionID { get; set; }

        [Required]        
        public int LocalID { get; set; }

     }

//Table C
public class Local
    {
        [Key]
        public int ID { get; set; }

        [Required]        
        public string Name { get; set; }

        [Required]        
        public int Localip { get; set; }
     }

What is the desired query Questions that are not answered by the Local How do you use except in the two matrices using ? With Entity Framework In Asp.net MVC I want to show a list of questions that are not answered?

string ip = Request.UserHostAddress;
var answerip = db.Answer.Where(l => l.Local.Localip == ip );
var quslist = db.Qustions.Except(answerip);

Answer 1

List<int> tempIdList = answeripE.Select(q => q.ID).ToList();
var quslist = db.Qustion.Where(q => !tempIdList.Contains(q.ID));
