Question

I am trying to inherit from Dictionary<K,V>, but my problem is, that when the Dictionary.Keys are being queried, I want to override them. (that is, the KeyCollection) of the dictionary.

How can that be solved?

thanks

Answer 1

• Encapsulate Dictionary<K,V>

and

• Implement IDictionary<K,V>.

---

or

public new YourType Keys
{
    get
    {
        return yourVersion;
    }
}

Note:

• IDictionary<K,V>.Keys has type ICollection<Key>

• Dictionary<K,V>.Keys has type Dictionary<K, V>.KeyCollection but it’s marked as sealed so you will not be able to inherit it, so option 1 seems to be more realistic.
