PokerFormationChecker 1.1.0

GenericPokerFormationChecker

A class that can identify poker hands, for .NET 8.0.

Install version 1.1.0 from NuGet:

Install-Package PokerFormationChecker

Example code:

Note that you must call the CheckFormation method before getting any formation information from the formation checker.

using System;
using Winsoft.Gaming.GenericPokerFormationChecker;

namespace ConsoleApplication1;

class Program
{
    static void Main(string[] args)
    {
        //Create a formation checker. Add five cards as string.
        var fm = new FormationChecker("HRT02, SPD03, HRT04, DMN05, CLB06"); //Input. Exception if string contains errors.

        //This will give true the formation is expressed correctly.
        fm.CheckFormation();

        //What is it?
        Console.WriteLine(fm.ToString()); //Output
    }
}

Input in example above:

HRT02, SPD03, HRT04, DMN05, CLB06

Output from example above:

FORMATION=STRAIGHT,SCORE=0420,HAND=HRT02*-SPD03*-HRT04*-DMN05*-CLB06*

Star (*) denotes that the card is included in a formation.

Sample input 2:

CLB06, SPD03, DMN07, DMN05, HRT06

Output from sample input 2:

FORMATION=PAIR,SCORE=0112,HAND=SPD03-DMN05-HRT06*-CLB06*-DMN07

Sample input 3:

SPD08, SPD09, DMN08, DMN09, CLB08

Output from sample input 3:

FORMATION=FULL-HOUSE,SCORE=0642,HAND=DMN08*-CLB08*-SPD08*-DMN09*-SPD09*

Sample input 3:

HRTAC, SPDAC, DMNAC, DMNKN, CLBAC

Output from sample input 3:

FORMATION=4-OF-A-KIND,SCORE=0756,HAND=DMNKN-HRTAC*-DMNAC*-CLBAC*-SPDAC*

Sample input 4:

HRTAC, SPDKN, DMN10, DMNKI, CLBQU

Output from sample input 4:

FORMATION=STRAIGHT,SCORE=0460,HAND=DMN10*-SPDKN*-CLBQU*-DMNKI*-HRTAC*

Sample input 5:

DMN02, DMNKN, CLBAC, HRT05, CLB09

Output from sample input 6:

FORMATION=NOTHING,SCORE=0014,HAND=DMN02-HRT05-CLB09-DMNKN-CLBAC*

Only one present star (*) denotes that no formation was found, and the hand score is equal to the score of the card with the highest score.

In version 1.0.5 or higher is the Hand class is self contained.
