Question

I’m writing myself a class library to manage Active Directory.

I have an interface:

Public Interface ISourceAnnuaire(Of T as {IGroupe, ITop, IUniteOrganisation, IUtilisateur})
    Readonly Property Changements As Dictionary(Of T, HashSet(Of String))
End Interface

This Changements property is used to save in memory the changes that occur on a particular element that is part of the source.

However, I am stuck with .NET Framework 2.0. What would be the closest .NET 2.0 for HashSet(Of String)?

Answer 1

Either use the non-generic Hashtable or hack a dictionary and use it’s key collection.

Public class HashSetHack<T> : //Whatever collection interfaces you need.
{
    private readonly Dictionary<T, object> dict = new Dictionary<T, object>();

    //whatever code you need to wrap the interfaces using dict.Keys eg:

    public void Add(T value)
    {
      dict.add(value, null);
    }
}
