Card aceOfSpades = new Card(Suit.Spades, Rank.Ace);
Card fiveOfDiamonds = new Card(Suit.Diamonds, Rank.Five); if (fiveOfDiamonds.Value > aceOfSpades.Value) { Console.WriteLine("Five of Diamonds is worth more than Ace of Spades!"); }In this example, two Card objects are created and their values are compared. The Value property is a calculated numeric value that takes into account the rank and suit of the card. The library is most likely included as a custom library for a specific application or game.
