Sets

What is translated > Types > Sets

A Delphi set is simulated in the C# VCL by the class TSet in DelphiSets.cs.

public class TSet : IEnumerable

Every TSet consists of 256 bits, which can be set or unset.

var

CharSet: set Of 'a'..'z';

NumberSet: set Of 1..10;

->

private static TSet CharSet = new TSet();

private static TSet NumberSet = new TSet();

A set is created on the fly, if there is no explicit type-declaration of a set, as e.g. in:

MySet := ['a','b','c'];

->

MySet = new TSet() << 'a' << 'b' << 'c';

An example of a set constant is:

type

  TDay = (dMon, dTue, dWed, dThu, dFri, dSat, dSun);

const

  cDays: set Of TDay = [dMon .. dSun];

-> 

public enum TDay {dMon,

           dTue,

           dWed,

           dThu,

           dFri,

           dSat,

           dSun };

public static TSet cDays = TSet() << 

          (int) dMon << (int) dTue << (int) dWed << (int) dThu << (int) dFri << (int) dSat << 

          (int) dSun;
