The Standard Poker Hand Evaluator generates an internal list of every possible 5 card poker hand rank (there are 7,462 of them), and associates each of those hands with an ordered list of prime numbers which can be looked up by multiplying the prime numbers associated with each of the 5 cards in the hand. Each possible hand also has an associated rank which is used to compare hands to determine winners and losers in a given round.

Usage is relatively simple. The programmer creats a 'Deck', deals 5 cards to each of one or more 'Hand's, and then compares (or sorts) the hands to rank them from best to worst.

No, the really,.really. efficient way to do poker hand evaluation is the one I linked to in the 4th comment. But understanding that method requires you to understand some serious math. My method is less efficient, but more understandable. April 10, 2009 at 8:53 AM. Question: Hi, So I Need Help With Visual Basic Programming When The Poker Hands 1) Flush Any Five Cards Of The Same Suit, But Not In A Sequence, 2) Straight Five Cards In A Sequence, But Not Of The Same Suit, 3) Royal Flush A, K, Q, J, 10, All The Same Suit, 4) Four Of A Kind All Four Cards Of The Same Rank, 5) Full House Three Of A Kind With A Pair. Here's the start of a poker hand evaluation project. So far it will tell you the cards that were dealt and if they included 4 of a kind, 3 of a kind, or a pair. Code could be added tell the rank of those (like '3 kings') and of course the other hand possibilities. Mar 11, 2017 VB poker hand evaluator closed Ask Question 0. My class programming project is to create a program that allows you to input numbers and letters to specify a card number and suit (e.g. 2 and D = 2 of Diamonds). Then you just have to count the number of pairs, quads and trips to get the result for a bunch of hands. Poker Hand evaluation.

The hands and individual cards have custom 'ToString' formats to accomodate short or verbose hand or card descriptions. For example, a hand might be displayed as 'AhAsAcAdKc' or 'Ace of Hearts, Ace of Spades, Ace of Clubs, Ace of Diamonds, King of Clubs' or 'Four Aces', depending on how the ToString method is called.

Testing on a gaming laptop was easily able to do the following steps 100,000 times in 1 second:Create and shuffle a deck of cards.Deal 10 hands, 5 cards each.Sort the hands from best to worst.

Basic usage example:

I'm writing a game of Texas Hold'Em in VB.NET and C#, and need to build some logic on calculating the resulting poker hand from a player's two cards and the cards on the table (totalling 7 in Texas Hold'Em).
For example:
Players cards: 7H, JS
Cards on table: TD, 2H, 8H, 7C, 9S
In this case the player has a Jack high straight - 7H, 8H, 9S, TD, JS. The algorithm also has to discern that even though the player also has a pair (7H, 7C) the real hand is the straight.
I tried writing my own logic, but it ended up being 250+ lines of code by the time it could detect a royal flush. I've seen some code around that is meant to do it, but most of it is either in C/C++ or for other versions of poker. Hand

I can write my own logic to discern a winner from a list of hands (i.e. that 3 of a kind beats two pair, and that an ace high straight beats a ten high straight). However, what I'm looking for is a function (or class) written in C# or VB.NET to return a poker hand (e.g. 'Two Pair - 3s and Jacks' or 'Four Aces') from a set of cards.

I've attached the VB.NET code for my structures and enums, but I can easily convert from another result format.
