How to Serialize collection

Question

I have class with property of type ISet. I want to serialize that class but don't know how to do with ISet.

[Serializable]    
class Question: ISerializable
{
  private int id;
  public int Id
  {
    get{return id;}
    set{id = value;}
  }

  private ISet answerChoice;
  public ISet AnswerChoices
  {
   get{return answerChoices;}
   set { answerChoices = value; }
  }

  public Question(SerializationInfo info, StreamingContext context)
  {
       id = info.GetInt32("id");
       answerChoices = //how to deserialize this collection
  }

  void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
  {
       info.AddValue("id", id);
       info.AddValue("ac", answerChoices);
  }
}

Do anyone try to make the same? Please, help me.

Are you talking about the ISet generic interface introduced in .Net 4.0? http://msdn.microsoft.com/en-us/library/dd412081.aspx — Daniel A.A. Pelsmaeker, Aug 26 '10 at 12:05
I mean Iesi.Collections.ISet from NHibernate, but If you change ISet to IList my question don't change. — Kate, Aug 26 '10 at 12:11

How about:

info.GetValue("ac",...);

And why do you implement you own serialization if you do not add any additional value?

And why do you implement you own serialization if you do not add any additional value? --- To add object to ViewState you should implement ISerializable interface - it is a rule! How about: info.GetValue("ac",...); --- What I should write in place of ellipsis? – Kate Aug 26 '10 at 12:19
No you do not, you just need to mark it as serializable(and make sure it is serializable) – Alex Reitbort Aug 26 '10 at 12:33

@Kate, info.GetValue("ac", typeof(ISet)) should work. @Alex, @Kate - note that for serialization to work as above, type implementing ISet has to be serializable. – VinayC Aug 26 '10 at 12:50
Thank you very mutch. It is so simple, why i don't think about it! – Kate Aug 26 '10 at 13:18
