Voici un exemple d'une classe permettant d'afficher un triangle Pascal écrit en C# (C Sharp):

using System; using System.Collections.Generic; using System.Text; namespace triangle {     class Program     {         static void Main(string[] args)         {             // Triangle de nombre de Pascal             for ( int i = 0; i < 10; i++) {                  for ( int j =0; j <= i; j++) {                      Console.Write(" "+j*i);                  }              Console.WriteLine();          }              // Dessin Triangle         for ( int i = 0; i < 13; i++) {              for ( int j = 0; j <= 13-i; j++) Console.Write(" ");             Console.Write("< ");              for ( int j = 0; j <= i+i; j++) Console.Write("x ");              Console.WriteLine("*");         }    }      } }

on obtiendra le résultat suivant:

0 0 1 0 2 4 0 3 6 9 0 4 8 12 16 0 5 10 15 20 25 0 6 12 18 24 30 36 0 7 14 21 28 35 42 49 0 8 16 24 32 40 48 56 64 0 9 18 27 36 45 54 63 72 81                             < x *                           < x x x *                         < x x x x x *                       < x x x x x x x *                     < x x x x x x x x x *                   < x x x x x x x x x x x *                 < x x x x x x x x x x x x x *               < x x x x x x x x x x x x x x x *             < x x x x x x x x x x x x x x x x x *           < x x x x x x x x x x x x x x x x x x x *         < x x x x x x x x x x x x x x x x x x x x x *       < x x x x x x x x x x x x x x x x x x x x x x x *     < x x x x x x x x x x x x x x x x x x x x x x x x x *
