Remove specific cards in a deck

Question

So I made a deck of cards with enums. But now I need to delete all the cards from 2 to 6 in the different suits through a List<T> . This piece of the code is given:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    var d = new Deck();
    Log(Converteer.ToString(d), "NIEUWE DEK");
     // this works

   d.RemoveNonManilleCards();
   Log(Converteer.ToString(d, 8), "MANILLE-DECK");
    // should be ->
    // ♠A -  ♠7 -  ♠8 -  ♠9 - ♠10 -  ♠B -  ♠D -  ♠H
    // ♥A -  ♥7 -  ♥8 -  ♥9 - ♥10 -  ♥B -  ♥D -  ♥H
    // ♣A -  ♣7 -  ♣8 -  ♣9 - ♣10 -  ♣B -  ♣D -  ♣H
   // ♦A -  ♦7 -  ♦8 -  ♦9 - ♦10 -  ♦B -  ♦D -  ♦H

And this is the deck being created and the void for deleting the cards. But I think I'm doing it completely wrong.

public partial class Deck : List<Card>
{
    public Deck()
    {
        MakeDeck();
    }
    protected virtual void MakeDeck()
    {
        foreach (Suit k in System.Enum.GetValues(typeof(Suit)))
        {
            foreach (Rank n in System.Enum.GetValues(typeof(Rank)))
            {
                this.Add(new Card(k, n));
            }
        }
    }

    public void RemoveNonManilleCards()
    {
        foreach (Suit k in System.Enum.GetValues(typeof(Suit)))
        {
            foreach (Rank n in System.Enum.GetValues(typeof(Rank)))
            {
                this.RemoveRange(1, 5);
            }
        }

    }

Can some of you point me in the right direction?

Answer 1

I think that I found how to fix the problem

public void RemoveNonManilleCards()
{
  for (int index = Count - 1; index >= 0; --index)
  {
    Kaart kaart = this[index];
    if (card.rank>= Rank.Two&& card.Rank<= Rank.Zes)
      this.RemoveAt(index);
  }

Thanks for the answers!
