Remove object from generic list by id

Question

I have a domain class like this:

public class DomainClass
{
  public virtual string name{get;set;}
  public virtual IList Notes{get;set;}
}
         


        

Answer 1

If you can change the datastructure I would suggest using a Dictionary. Than you can go with:

public class DomainClass
{
  public virtual string name{get;set;}
  public virtual IDictionary Notes {get; set;}

  //Helper property to get the notes in the dictionary
  public IEnumerable AllNotes
  {
    get
    {
      return notes.Select (n => n.Value);
    }
  }

  public virtual void RemoveNote(int id)
  {
     Notes.Remove(id);
  }

}

If ID is not unique use IDictionary> instead.
