How can you inherit from a sealed class using reflection in .Net?

It MIGHT (would increase the size if I could). According to the guys on freenode, it would involved modifying the byte code, using Reflection.Emit, and handing the JIT a new set of byte code.

Not that I KNOW how ... it was just what they thought.

Create a new class called GenericKeyValueBase

put this in it

  public class GenericKeyValueBase<TKey,TValue>
    {
        public TKey Key;
        public TValue Value;

        public GenericKeyValueBase(TKey ItemKey, TValue ItemValue)
        {
            Key = ItemKey;
            Value = ItemValue;
        }
    }

And inherit from that plus you can add additional extension methods for Add/Remove (AddAt and RemoveAt) to your new derived class (and make it a collection/dictionary) if you are feeling really cool.

A simple implentation example where you would use a normal System.Collections.Generic.KeyValuePair for a base, but instead can use the above code

  class GenericCookieItem<TCookieKey, TCookieValue> : GenericKeyValueBase<TCookieKey,TCookieValue>
    {
        public GenericCookieItem(TCookieKey KeyValue, TCookieValue ItemValue) : base(KeyValue, ItemValue)
        {
        }
    }
